Constructor Detail

XSDFacet

public XSDFacet()

Creates a new Facet element

Method Detail

prepareAttributes

public void prepareAttributes()
                       throws SchemaException

Validate and process the attributes on this element in the schema document

Specified by:

prepareAttributes in class SchemaElement

Throws:

SchemaException - if any errors are found in the attributes

validate

public void validate(SchemaCompiler compiler)
              throws SchemaException

Validate this schema element, checking all document-level constraints

Overrides:

validate in class AnnotationParent

Parameters:

compiler -

Throws:

SchemaException - if any XML representation constraints are violated

getFacet

public Facet getFacet()

Get the Facet "component" created from this facet definition

Returns:

the Facet component (not strictly a schema component, but effectively part of one)

getSequenceNumber

protected final long getSequenceNumber()

Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and document nodes) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position. For nodes added by XQUery Update, the sequence number is -1L

Overrides:

getSequenceNumber in class NodeImpl

Returns:

the sequence number if there is one, or -1L otherwise.

getRawSequenceNumber

protected final int getRawSequenceNumber()

setRawSequenceNumber

protected final void setRawSequenceNumber(int seq)

setChildren

protected final void setChildren(Object children)

Set the children of this node

Parameters:

children - null if there are no children, a single NodeInfo if there is one child, an array of NodeInfo if there are multiple children

hasChildNodes

public final boolean hasChildNodes()

Determine if the node has any children.

Specified by:

hasChildNodes in interface NodeInfo

Overrides:

hasChildNodes in class NodeImpl

Returns:

true if the node has any children, false if the node has no children.

getNumberOfChildren

public final int getNumberOfChildren()

Determine how many children the node has

Returns:

the number of children of this parent node

enumerateChildren

protected final AxisIterator enumerateChildren(NodeTest test)

Get an enumeration of the children of this node

Parameters:

test - A NodeTest to be satisfied by the child nodes, or null if all child node are to be returned

Returns:

an iterator over the children of this node

getFirstChild

public final NodeInfo getFirstChild()

Get the first child node of the element

Overrides:

getFirstChild in class NodeImpl

Returns:

the first child node of the required type, or null if there are no children

getLastChild

public final NodeInfo getLastChild()

Get the last child node of the element

Overrides:

getLastChild in class NodeImpl

Returns:

the last child of the element, or null if there are no children

getNthChild

protected final NodeImpl getNthChild(int n)

Get the nth child node of the element (numbering from 0)

Parameters:

n - identifies the required child

Returns:

the last child of the element, or null if there is no n'th child

removeChild

protected void removeChild(NodeImpl child)

Remove a given child

Parameters:

child - the child to be removed

getStringValue

public String getStringValue()

Return the string-value of the node, that is, the concatenation of the character content of all descendent elements and text nodes.

Returns:

the accumulated character content of the element, including descendant elements.

See Also:

Item.getStringValueCS()

getStringValueCS

public CharSequence getStringValueCS()

Description copied from class: NodeImpl

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String.

Specified by:

getStringValueCS in interface Item

Specified by:

getStringValueCS in interface ValueRepresentation

Overrides:

getStringValueCS in class NodeImpl

Returns:

the string value of the item

See Also:

Item.getStringValue()

addChild

protected void addChild(NodeImpl node,
                        int index)

Add a child node to this node. For system use only. Note: normalizing adjacent text nodes is the responsibility of the caller.

Parameters:

node - the node to be added as a child of this node. This must be an instance of NodeImpl. It will be modified as a result of this call (by setting its parent property and sibling position)

index - the position where the child is to be added

insertChildren

public void insertChildren(NodeInfo[] source,
                           boolean atStart,
                           boolean inherit)

Insert a sequence of nodes as children of this node.

This method takes no action unless the target node is a document node or element node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.

The supplied nodes will form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, or they may be copied, at the discretion of the implementation.

Specified by:

insertChildren in interface MutableNodeInfo

Overrides:

insertChildren in class NodeImpl

Parameters:

source - the nodes to be inserted. The implementation determines what implementation classes of node it will accept; this implementation will accept text, comment, and processing instruction nodes belonging to any implementation, but elements must be instances of ElementImpl. The supplied nodes will be modified in situ, for example to change their parent property and to add namespace bindings, if they are instances of ElementImpl; otherwise they will be copied. If the nodes are copied, then on return the supplied source array will contain the copy rather than the original.

atStart - true if the new nodes are to be inserted before existing children; false if they are to be inserted after existing children

inherit - true if the inserted nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared

Throws:

IllegalArgumentException - if the supplied nodes use a node implementation that this implementation does not accept.

insertChildrenAt

protected void insertChildrenAt(NodeInfo[] source,
                                int index,
                                boolean inherit)

Insert children before or after a given existing child

Parameters:

source - the children to be inserted. We allow any kind of text, comment, or processing instruction node, but element nodes must be instances of this NodeInfo implementation.

index - the position before which they are to be inserted: 0 indicates insertion before the first child, 1 insertion before the second child, and so on.

inherit - true if the inserted nodes are to inherit the namespaces that are in-scope for their new parent; false if such namespaces should be undeclared on the children

replaceChildrenAt

protected void replaceChildrenAt(NodeInfo[] source,
                                 int index,
                                 boolean inherit)

Replace child at a given index by new children

Parameters:

source - the children to be inserted

index - the position at which they are to be inserted: 0 indicates replacement of the first child, replacement of the second child, and so on. The effect is undefined if index is out of range

inherit - set to true if the new child elements are to inherit the in-scope namespaces of their new parent

Throws:

IllegalArgumentException - if any of the replacement nodes is not an element, text, comment, or processing instruction node

compact

public void compact(int size)

Compact the space used by this node

Parameters:

size - the number of actual children
