net.sf.saxon.pattern.ContentTypeTest
public class ContentTypeTest
NodeTest is an interface that enables a test of whether a node matches particular conditions. ContentTypeTest tests for an element or attribute node with a particular type annotation.
| Constructor Summary | |
|---|---|
ContentTypeTest(int nodeKind,
SchemaType schemaType,
Configuration config)
Create a ContentTypeTest |
|
| Method Summary | |
|---|---|
boolean |
equals(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) |
SchemaType |
getContentType()
Get the content type allowed by this NodeTest (that is, the type annotation of the matched nodes). |
double |
getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern |
int |
getNodeKind()
|
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. |
SchemaType |
getSchemaType()
|
ItemType |
getSuperType(TypeHierarchy th)
Get the type from which this item type is derived by restriction. |
int |
hashCode()
Returns a hash code value for the object. |
boolean |
isAtomizable()
Ask whether values of this type are atomizable |
boolean |
isNillable()
The test is nillable if a question mark was specified as the occurrence indicator |
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. |
void |
setNillable(boolean nillable)
Indicate whether nilled elements should be matched (the default is false) |
String |
toString()
|
void |
visitNamedSchemaComponents(SchemaComponentVisitor visitor)
Visit all the schema components used in this ItemType definition |

nodeKind - the kind of nodes to be matched: always elements or attributesschemaType - the required type annotation, as a simple or complex schema typeconfig - the Configuration, supplied because this KindTest needs access to schema information| Method Detail |

public ItemType getSuperType(TypeHierarchy th)
NodeTestIn 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.

public boolean matches(int nodeKind,
NodeName name,
int annotation)
matches in class NodeTestnodeKind - 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
