Constructor Detail

SchemaElementTest

public SchemaElementTest(ElementDecl element)

Constructor

Parameters:

element - The element declaration of the named element

Method Detail

getElementDeclaration

public ElementDecl getElementDeclaration()

Get the element declaration

Returns:

the element declaration that this schema-element relates to (the head of the substitution group)

matches

public boolean matches(int nodeKind,
                       int nameCode,
                       int annotation)

Test whether this node test is satisfied by a given node

Specified by:

matches in class NodeTest

Parameters:

nodeKind - The type of node to be matched

nameCode - identifies the expanded name of the node to be matched

annotation - The actual content type of the node

matches

public boolean matches(TinyTree tree,
                       int nodeNr)

Test whether this node test is satisfied by a given node on a TinyTree. The node must be a document, element, text, comment, or processing instruction node. This method is provided so that when navigating a TinyTree a node can be rejected without actually instantiating a NodeInfo object.

Overrides:

matches in class NodeTest

Parameters:

tree - the TinyTree containing the node

nodeNr - the number of the node within the TinyTree

Returns:

true if the node matches the NodeTest, otherwise false

matches

public boolean matches(NodeInfo node)

Test whether this node test is satisfied by a given node. This alternative method is used in the case of nodes where calculating the fingerprint is expensive, for example DOM or JDOM nodes.

Overrides:

matches in class NodeTest

Parameters:

node - the node to be matched

matchesAnnotation

public static boolean matchesAnnotation(Configuration config,
                                        SchemaType required,
                                        int annotation)

Determine whether the type annotation of an element or attribute instances matches the required type of the element or attribute declaration named in a schema-element() or schema-attribute() test

Parameters:

config - the Saxon configuration

required - the required type of the declaration named in the schema-element() or schema-attribute test

annotation - the actual type annotation of the instance

Returns:

true if there is a match, false otherwise

getDefaultPriority

public final double getDefaultPriority()

Determine the default priority of this node test when used on its own as a Pattern

Specified by:

getDefaultPriority in class NodeTest

getPrimitiveType

public int getPrimitiveType()

Determine the types of nodes to which this pattern applies. Used for optimisation. For patterns that match nodes of several types, return Type.NODE

Specified by:

getPrimitiveType in interface ItemType

Overrides:

getPrimitiveType in class NodeTest

Returns:

the type of node matched by this pattern. e.g. Type.ELEMENT or Type.TEXT

getNodeKindMask

public int getNodeKindMask()

Get a mask indicating which kinds of nodes this NodeTest can match. This is a combination of bits: Type.ELEMENT for element nodes, Type.TEXT for text nodes, and so on.

Overrides:

getNodeKindMask in class NodeTest

getRequiredNodeNames

public IntSet getRequiredNodeNames()

Get the set of node names allowed by this NodeTest. This is returned as a set of Integer fingerprints. A null value indicates that all names are permitted (i.e. that there are no constraints on the node name. The default implementation returns null.

Overrides:

getRequiredNodeNames in class NodeTest

getContentType

public SchemaType getContentType()

Get the content type allowed by this NodeTest (that is, the type annotation of the matched nodes). Return AnyType if there are no restrictions. The default implementation returns AnyType.

Overrides:

getContentType in class NodeTest

getHeadFingerprint

public int getHeadFingerprint()

Get the fingerprint of the head of the substitution group

Returns:

the fingerprint of the head of the substitution group

visitNamedSchemaComponents

public void visitNamedSchemaComponents(SchemaComponentVisitor visitor)
                                throws XPathException

Visit all the schema components used in this ItemType definition

Specified by:

visitNamedSchemaComponents in interface ItemType

Overrides:

visitNamedSchemaComponents in class NodeTest

Parameters:

visitor - the visitor class to be called when each component is visited

Throws:

XPathException

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(NamePool pool)

Description copied from class: NodeTest

Display the type descriptor for diagnostics

Specified by:

toString in interface ItemType

Overrides:

toString in class NodeTest

Parameters:

pool - the name pool

Returns:

a string representation of the type, in notation resembling but not necessarily identical to XPath syntax

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object
