matches

public boolean matches(Node node)

Description copied from interface: Pattern

Specified by:

matches in interface Pattern

Parameters:

node - DOCUMENT ME!

true if the pattern matches the given DOM4J node.

getText

public String getText()

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 interface Pattern

Returns:

getUnionPatterns

public Pattern[] 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 interface Pattern

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 interface Pattern

Returns:

the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.

getMatchesNodeName

public String 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 interface Pattern

Returns:

the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.
