Constructor Detail

XSDAttributeGroup

public XSDAttributeGroup()

Creates a new AttributeGroup 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

isReference

public boolean isReference()

Is this an attribute group declaration or a reference?

getAttributeGroupDecl

public AttributeGroupDecl getAttributeGroupDecl()
                                         throws SchemaException

Returns the AttributeGroupDecl created by this AttributeGroup declaration.

Returns:

the AttributeGroupDecl corresponding to this xs:attribute-group element if it is a global attribute group declaration; if it is an attribute group reference, return null.

Throws:

SchemaException

getAttributeGroupReference

public AttributeGroupReference getAttributeGroupReference()
                                                   throws SchemaException

Return the AttributeGroupReference, if this is a reference

Returns:

the AttributeGroupReference, or null if this is not a reference

Throws:

SchemaException

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

Additional processing after all the children of this element have been validated.

Overrides:

postValidate in class SchemaElement

Parameters:

compiler -

Throws:

SchemaException - if errors are found

getRedefinedAttributeGroup

public AttributeGroupDecl getRedefinedAttributeGroup()

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.

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()

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

compact

public void compact(int size)

Compact the space used by this node

Parameters:

size - the number of actual children
