XSDSimpleTypeRestriction

public XSDSimpleTypeRestriction()

Create a restriction of a simple type

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 SchemaElement

Parameters:

compiler - used for error reporting

Throws:

SchemaException - if any XML representation constraints are violated

isFinalState

protected boolean isFinalState(int state)

Description copied from class: SchemaElement

For elements whose content model is parsed using a finite state machine, test whether a given state is a final state. The default implementation of this method is never used; it exists for the benefit of subclasses that do not use this mechanism

Overrides:

isFinalState in class SchemaElement

Parameters:

state - the state to be tested

Returns:

true if the given state is a final state

postValidate

public void postValidate(SchemaCompiler compiler)
                  throws SchemaException

Process child elements after validation

Overrides:

postValidate in class SchemaElement

Parameters:

compiler - used for error reporting

Throws:

SchemaException - if errors are found

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.

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 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()

useChildrenArray

protected void useChildrenArray(NodeImpl[] array)

Supply an array to be used for the array of children. For system use only.

Parameters:

array - the array to be used

addChild

public 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

index - the position where the child is to be added

insertChildren

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

Insert copies of 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 be copied to form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed.

Specified by:

insertChildren in interface MutableNodeInfo

Overrides:

insertChildren in class NodeImpl

Parameters:

source - the nodes to be inserted

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

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

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

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
