java.lang.Objectnet.sf.saxon.pattern.NodeTest
net.sf.saxon.pattern.IdrefTest
NodeTest is an interface that enables a test of whether a node matches particular conditions. IdrefTest is a test that cannot be represented directly in XPath or XSLT patterns, but which is used internally for matching IDREF nodes: it tests whether the node has the is-idref property
Beware: The TypeHierarchy.computeRelationship() method does not work with this kind of ItemType.
Constructor Summary | |
IdrefTest(int nodeKind)
Create a IdrefTest |
Method Summary | |
boolean |
equals(java.lang.Object other)
Indicates whether some other object is "equal to" this one. |
AtomicType |
getAtomizedItemType()
Get the item type of the atomic values that will be produced when an item of this type is atomized (assuming that atomization succeeds) |
double |
getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern |
int |
getNodeKindMask()
Get a mask indicating which kinds of nodes this NodeTest can match. |
int |
getPrimitiveType()
Determine the types of nodes to which this pattern applies. |
ItemType |
getSuperType(TypeHierarchy th)

int |
hashCode()
Returns a hash code value for the object. |
boolean |
matches(int nodeKind,

Test whether this node test is satisfied by a given node |
boolean |
matches(NodeInfo node)

public ItemType getSuperType(TypeHierarchy th)
NodeTest
In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.
