Constructor Detail

XSDIdentityConstraint

public XSDIdentityConstraint()

Creates a new IdentityConstraint 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

getIdentityConstraint

public IdentityConstraint getIdentityConstraint()

Returns the IdentityConstraint created.

Returns:

the IdentityConstraint created.

validate

public void validate(SchemaCompiler compiler)
              throws SchemaException

Validate this schema element, checking all document-level constraints

Overrides:

validate in class SchemaElement

Parameters:

compiler -

Throws:

SchemaException - if any XML representation constraints are violated

postValidate

public void postValidate(SchemaCompiler compiler)
                  throws SchemaException

Process the child elements after validation

Overrides:

postValidate in class SchemaElement

Parameters:

compiler -

Throws:

SchemaException

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.

enumerateChildren

public 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

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

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

public void useChildrenArray(NodeImpl[] array)

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

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.

compact

public void compact(int size)

Compact the space used by this node
