matches
Test whether this node test is satisfied by a given node. This method is only fully supported for a subset of NodeTests, because it doesn't provide all the information needed to evaluate all node tests. In particular (a) it can't be used to evaluate a node test of the form element(N,T) or schema-element(E) where it is necessary to know whether the node is nilled, and (b) it can't be used to evaluate a node test of the form document-node(element(X)). This in practice means that it is used (a) to evaluate the simple node tests found in the XPath 1.0 subset used in XML Schema, and (b) to evaluate node tests where the node kind is known to be an attribute.- Specified by:
matches
in classNodeTest
- Parameters:
nodeKind
- The kind of node to be matchedname
- identifies the expanded name of the node to be matched. The value should be null for a node with no name.annotation
- The actual content type of the node- Returns:
- true if the node matches this node test
-
getMatcher
Description copied from class:NodeTest
Get a matching function that can be used to test whether numbered nodes in a TinyTree or DominoTree satisfy the node test. (Calling this matcher must give the same result as callingmatchesNode(tree.getNode(nodeNr))
, but it may well be faster).- Overrides:
getMatcher
in classNodeTest
- Parameters:
tree
- the tree against which the returned function will operate- Returns:
- an IntPredicate; the matches() method of this predicate takes a node number as input, and returns true if and only if the node identified by this node number matches the node test.
-
test
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.- Specified by:
test
in interfaceNodePredicate
- Overrides:
test
in classNodeTest
- Parameters:
node
- the node to be matched- Returns:
- true if the node test is satisfied by the supplied node, 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 interfaceItemType
- Specified by:
getDefaultPriority
in classNodeTest
- Returns:
- the default priority for the pattern
-
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 interfaceItemType
- Overrides:
getPrimitiveType
in classNodeTest
- Returns:
- the type of node matched by this pattern. e.g. Type.ELEMENT or Type.TEXT
-
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 classNodeTest
- Returns:
- the set of integer fingerprints of the node names that this node test can match; or absent if the set of names cannot be represented (for example, with the name tests *:xxx or xxx:*)
-
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 classNodeTest
- Returns:
- the type annotation that all nodes matching this NodeTest must satisfy
-
toString
-
hashCode
public int hashCode()Returns a hash code value for the object. -
equals
-
getBasicAlphaCode
Description copied from class:NodeTest
Get an alphabetic code representing the type, or at any rate, the nearest built-in type from which this type is derived. The codes are designed so that for any two built-in types A and B, alphaCode(A) is a prefix of alphaCode(B) if and only if A is a supertype of B.- Specified by:
getBasicAlphaCode
in interfaceItemType
- Overrides:
getBasicAlphaCode
in classNodeTest
- Returns:
- the alphacode for the nearest containing built-in type
-
explainMismatch
Get extra diagnostic information about why a supplied item does not conform to this item type, if available. If extra information is returned, it should be in the form of a complete sentence, minus the closing full stop. No information should be returned for obvious cases.- Specified by:
explainMismatch
in interfaceItemType
- Overrides:
explainMismatch
in classNodeTest
- Parameters:
item
- the item that doesn't match this typeth
- the type hierarchy cache- Returns:
- optionally, a message explaining why the item does not match the type
-
