getPriority
public double getPriority()Description copied from interface:Pattern
Returns the default resolution policy of the pattern according to the XSLT conflict resolution spec .- Specified by:
getPriority
in interfacePattern
- Returns:
- DOCUMENT ME!
-
getUnionPatterns
Description copied from interface:Pattern
If this pattern is a union pattern then this method should return an array of patterns which describe the union pattern, which should contain more than one pattern. Otherwise this method should return null.- Specified by:
getUnionPatterns
in interfacePattern
- Returns:
- an array of the patterns which make up this union pattern or null if this pattern is not a union pattern
-
getMatchType
public short getMatchType()Description copied from interface:Pattern
DOCUMENT ME!- Specified by:
getMatchType
in interfacePattern
- Returns:
- the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.
-
getMatchesNodeName
Description copied from interface:Pattern
For patterns which only match an ATTRIBUTE_NODE or an ELEMENT_NODE then this pattern may return the name of the element or attribute it matches. This allows a more efficient rule matching algorithm to be performed, rather than a brute force approach of evaluating every pattern for a given Node.- Specified by:
getMatchesNodeName
in interfacePattern
- Returns:
- the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.
