public class CombinedNodeTest extends NodeTest
ItemType.WithSequenceTypeCache
Constructor and Description |
---|
CombinedNodeTest(NodeTest nt1,
int operator,
NodeTest nt2)
Create a NodeTest that combines two other node tests
|
Modifier and Type | Method and Description |
---|---|
boolean |
equals(java.lang.Object other)
Indicates whether some other object is "equal to" this one.
|
java.lang.String |
generateJavaScriptItemTypeTest(ItemType knownToBe,
int targetVersion)
Generate Javascript code to test whether an item conforms to this item type
|
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)
|
NodeTest[] |
getComponentNodeTests()
Get the two parts of the combined node test
|
SchemaType |
getContentType()
Get the content type allowed by this NodeTest (that is, the type annotation of the matched nodes).
|
double |
getDefaultPriority()
Get the default priority of this nodeTest when used as a pattern.
|
int |
getFingerprint()
Get the name of the nodes matched by this nodetest, if it matches a specific name.
|
IntPredicate |
getMatcher(NodeVectorTree tree)
Get a matching function that can be used to test whether numbered nodes in a TinyTree
or DominoTree satisfy the node test.
|
StructuredQName |
getMatchingNodeName()
Get the name of the nodes matched by this nodetest, if it matches a specific name.
|
int |
getNodeKindMask()
Get a mask indicating which kinds of nodes this NodeTest can match.
|
int |
getOperator()
Get the operator used to combine the two node tests: one of
Token.UNION ,
Token.INTERSECT , Token.EXCEPT , |
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.
|
IntSet |
getRequiredNodeNames()
Get the set of node names allowed by this NodeTest.
|
UType |
getUType()
Get the corresponding
UType . |
int |
hashCode()
Returns a hash code value for the object.
|
boolean |
isAtomizable()
Ask whether values of this type are atomizable
|
boolean |
isNillable()
Determine whether the content type (if present) is nillable
|
boolean |
matches(int nodeKind,
NodeName name,
SchemaType annotation)
Test whether this node test is satisfied by a given node.
|
boolean |
matchesNode(NodeInfo node)
Test whether this node test is satisfied by a given node.
|
java.lang.String |
toExportString()
Return a string representation of this SequenceType suitable for use in export (SEF) files.
|
java.lang.String |
toString() |
void |
visitNamedSchemaComponents(SchemaComponentVisitor visitor)
Visit all the schema components used in this ItemType definition
