getUnionPatterns
public Pattern[] getUnionPatterns()
Description copied from class: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.- Overrides:
getUnionPatterns
in classPattern
- 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 class:Pattern
Returns the type of node the pattern matches.- Overrides:
getMatchType
in classPattern
- Returns:
ANY_NODE
unless overridden
-
getMatchesNodeName
public java.lang.String getMatchesNodeName()
Description copied from class: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.- Overrides:
getMatchesNodeName
in classPattern
- Returns:
- the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name
-
getText
public java.lang.String getText()
Description copied from class:Pattern
Returns a textual representation of this pattern
-
toString
public java.lang.String toString()
