  - getTypeAnnotation
```
public int getTypeAnnotation()
```
    Get the type annotation
    
    Specified by:
    
    getTypeAnnotation in interface NodeInfo
    
    Overrides:
    
    getTypeAnnotation in class AbstractNodeWrapper
    
    Returns:
    the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated as untypedAtomic for the purposes of obtaining the typed value).
    
    For elements and attributes, this is the type annotation as defined in XDM. For document nodes, it should be one of XS_UNTYPED if the document has not been validated, or XS_ANY_TYPE if validation has taken place (that is, if any node in the document has an annotation other than Untyped or UntypedAtomic).
  - getSchemaType

  - isSameNodeInfo
```
public boolean isSameNodeInfo(NodeInfo other)
```
    Determine whether this is the same node as another node.
    Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)
    
    Specified by:
    
    isSameNodeInfo in interface NodeInfo
    
    Overrides:
    
    isSameNodeInfo in class AbstractNodeWrapper
    
    Parameters:
    other - the node to be compared with this node
    
    Returns:
    true if this Node object and the supplied Node object represent the same node in the tree.
  - equals
```
public boolean equals(Object other)
```
    The equals() method compares nodes for identity. It is defined to give the same result as isSameNodeInfo().
    
    Specified by:
    
    equals in interface NodeInfo
    
    Overrides:
    
    equals in class AbstractNodeWrapper
    
    Parameters:
    other - the node to be compared with this node
    
    Returns:
    true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree.
    Since:
    
    8.7 Previously, the effect of the equals() method was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics. It is safer to use isSameNodeInfo() for this reason. The equals() method has been defined because it is useful in contexts such as a Java Set or HashMap.
  - hashCode
```
public int hashCode()
```
    The hashCode() method obeys the contract for hashCode(): that is, if two objects are equal (represent the same node) then they must have the same hashCode()
    
    Specified by:
    
    hashCode in interface NodeInfo
    
    Overrides:
    
    hashCode in class AbstractNodeWrapper
    
    Since:
    
    8.7 Previously, the effect of the equals() and hashCode() methods was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics.
  - getSystemId
```
public String getSystemId()
```

    Overrides:
    
    getSystemId in class AbstractNodeWrapper
    
    Returns:
    the System Identifier of the entity in the source document containing the node, or null if not known. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot.
  - getBaseURI
```
public String getBaseURI()
```
    Get the Base URI for the node, that is, the URI used for resolving a relative URI contained in the node.
    
    Specified by:
    
    getBaseURI in interface NodeInfo
    
    Overrides:
    
    getBaseURI in class AbstractNodeWrapper

  - compareOrder
```
public int compareOrder(NodeInfo other)
```

    Specified by:
    
    compareOrder in interface NodeInfo
    
    Parameters:
    other - The other node, whose position is to be compared with this node
    
    Returns:
    -1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())
  - comparePosition
```
public int comparePosition(NodeInfo other)
```
    Determine the relative position of this node and another node, in document order, distinguishing whether the first node is a preceding, following, descendant, ancestor, or the same node as the second.
    The other node must always be in the same tree; the effect of calling this method when the two nodes are in different trees is undefined. If either node is a namespace or attribute node, the method should throw UnsupportedOperationException.
    
    Specified by:
    
    comparePosition in interface NodeInfo
    
    Overrides:
    
    comparePosition in class AbstractNodeWrapper

    AxisInfo.PRECEDING if this node is on the preceding axis of the other node; AxisInfo.FOLLOWING if it is on the following axis; AxisInfo.ANCESTOR if the first node is an ancestor of the second; AxisInfo.DESCENDANT if the first is a descendant of the second; AxisInfo.SELF if they are the same node.
    
    Throws:
    
    UnsupportedOperationException - if either node is an attribute or namespace
    Since:
    
    9.5
  - getStringValue
```
public String getStringValue()
```
    Return the string value of the node. The interpretation of this depends on the type of node. For an element it is the accumulated character content of the element, including descendant elements.

    getStringValue in interface Item
    
    Specified by:
    
    getStringValue in interface NodeInfo

    Returns:
    the string value of the item
    See Also:

    Specified by:
    
    getNameCode in interface NodeInfo
    
    Overrides:
    
    getNameCode in class AbstractNodeWrapper

  - getFingerprint
```
public int getFingerprint()

    Specified by:
    
    getFingerprint in interface NodeInfo
    
    Overrides:
    
    getFingerprint in class AbstractNodeWrapper
    
    Returns:

    Returns:
    The prefix of the name of the node.
  - getURI

    Description copied from class: AbstractNodeWrapper
    
    Return an iterator over the descendants of this node. This method is only called after checking that the node is an element or document node.
    
    Specified by:
    
    iterateDescendants in class AbstractNodeWrapper
    
    Parameters:
    nodeTest - a test that the returned descendants must satisfy
    includeSelf - true if this node is to be included in the result
    
    Returns:
    an iterator over the sibling nodes, in axis order.
  - getAttributeValue
```
public String getAttributeValue(String uri,
                       String local)
```
    Get the string value of a given attribute of this node
    
    Specified by:
    
    getAttributeValue in interface NodeInfo
    
    Overrides:
    
    getAttributeValue in class AbstractNodeWrapper
    
    Parameters:
    uri - the namespace URI of the attribute name. Supply the empty string for an attribute that is in no namespace
    local - the local part of the attribute name.
    
    Returns:
    the attribute value if it exists, or null if it does not exist. Always returns null if this node is not an element.

  - getRoot
```
public NodeInfo getRoot()
```
    Get the root node of the tree containing this node
    
    Specified by:
    
    getRoot in interface NodeInfo
    
    Overrides:
    
    getRoot in class AbstractNodeWrapper
    
    Returns:
    the NodeInfo representing the top-level ancestor of this node. This will not necessarily be a document node
  - getDocumentRoot
```
public DocumentInfo getDocumentRoot()
```
    Get the root node, if it is a document node.
    
    Specified by:
    
    getDocumentRoot in interface NodeInfo
    
    Returns:
    the DocumentInfo representing the containing document.
  - hasChildNodes
```
public boolean hasChildNodes()
```
    Determine whether the node has any children.
    Note: the result is equivalent to
    getEnumeration(Axis.CHILD, AnyNodeTest.getInstance()).hasNext()
    
    Specified by:
    
    hasChildNodes in interface NodeInfo
    
    Overrides:
    
    hasChildNodes in class AbstractNodeWrapper
    
    Returns:
    True if the node has one or more children
  - generateId
```
public void generateId(FastStringBuffer buffer)
```
    Get a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)
    
    Specified by:
    
    generateId in interface NodeInfo
    
    Parameters:
    buffer - a buffer to contain a string that uniquely identifies this node, across all documents
  - getDocumentNumber
```
public long getDocumentNumber()
```
    Get the document number of the document containing this node. For a free-standing orphan node, just return the hashcode.
    
    Specified by:
    
    getDocumentNumber in interface NodeInfo
    
    Overrides:
    
    getDocumentNumber in class AbstractNodeWrapper
    
    Returns:
    the document number of the document containing this node
  - copy
```
public void copy(Receiver out,
        int copyOptions,
        int locationId)
          throws XPathException
```
    Copy this node to a given outputter (deep copy)
    
    Specified by:
    
    copy in interface NodeInfo
    
    Overrides:
    
    copy in class AbstractNodeWrapper
    
    Parameters:
    out - the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.
    copyOptions - a selection of the options defined in CopyOptions
    locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information
    
    Throws:
    
    XPathException - if any downstream error occurs
  - getDeclaredNamespaces
```
public NamespaceBinding[] getDeclaredNamespaces(NamespaceBinding[] buffer)
```
    Get all namespace undeclarations and undeclarations defined on this element.
    
    Specified by:
    
    getDeclaredNamespaces in interface NodeInfo
    
    Overrides:
    
    getDeclaredNamespaces in class AbstractNodeWrapper
    
    Parameters:
    buffer - If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
    
    Returns:
    An array of integers representing the namespace declarations and undeclarations present on this element. For a node other than an element, return null. Otherwise, the returned array is a sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The top half word of each namespace code represents the prefix, the bottom half represents the URI. If the bottom half is zero, then this is a namespace undeclaration rather than a declaration. The XML namespace is never included in the list. If the supplied array is larger than required, then the first unused entry will be set to -1.
    
    For a node other than an element, the method returns null.
  - isId
```
public boolean isId()
```
    Determine whether this node has the is-id property
    
    Specified by:
    
    isId in interface NodeInfo
    
    Overrides:
    
    isId in class AbstractNodeWrapper
    
    Returns:
    true if the node is an ID
  - isIdref
```
public boolean isIdref()
```
    Determine whether this node has the is-idref property
    
    Specified by:
    
    isIdref in interface NodeInfo
    
    Overrides:
    
    isIdref in class AbstractNodeWrapper
    
    Returns:
    true if the node is an IDREF or IDREFS element or attribute
  - isNilled
```
public boolean isNilled()
```
    Determine whether the node has the is-nilled property
    
    Specified by:
    
    isNilled in interface NodeInfo
    
    Overrides:
    
    isNilled in class AbstractNodeWrapper
    
    Returns:
    true if the node has the is-nilled property
