net.sf.saxon.pattern.EmptySequenceTest
public final class EmptySequenceTest
NodeTest is an interface that enables a test of whether a node has a particular name and type. An EmptySequenceTest matches no nodes or atomic values: it corresponds to the type empty-sequence().
| Method Summary | |
|---|---|
double |
getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern |
static EmptySequenceTest |
getInstance()
Get a NoNodeTest instance |
int |
getNodeKindMask()
Get a mask indicating which kinds of nodes this NodeTest can match. |
ItemType |
getPrimitiveItemType()
Get the primitive item type corresponding to this item type. |
int |
getPrimitiveType()
Get the basic kind of object that this ItemType matches: for a NodeTest, this is the kind of node, or Type.Node if it matches different kinds of nodes. |
int |
hashCode()
Returns a hash code value for the object. |
boolean |
matches(int nodeKind,
NodeName name,
int annotation)
Test whether this node test is satisfied by a given node. |
boolean |
matches(NodeInfo node)
Test whether this node test is satisfied by a given node. |
boolean |
matches(TinyTree tree,
int nodeNr)
Test whether this node test is satisfied by a given node on a TinyTree. |
boolean |
matchesItem(Item item,
boolean allowURIPromotion,
Configuration config)
Test whether a given item conforms to this type |
String |
toString()
|
void |
visitNamedSchemaComponents(SchemaComponentVisitor visitor)
Visit all the schema components used in this ItemType definition |
