Method Detail

getObject2TableMap

@Deprecated
public java.util.LinkedHashMap<PatternObject,ObjectTable> getObject2TableMap()

Deprecated. since 1.2; for internal use only

Returns:

the map from pattern object to tables of matching values

getMatchTable

public ObjectTable getMatchTable(PatternObject pattern)

match

public ObjectTable match(java.lang.String patternObjectName,
                         java.lang.Object... startObjects)

Matches the pattern against the structure of objects that can be discovered from the start objects, and returns the table of matched values corresponding to the named pattern object.

Parameters:

patternObjectName - the name of the pattern object the results are requested for

startObjects - the root objects for object structure discovery

Returns:

the table of matched values corresponding to the named pattern object

Throws:

NoApplicableConstraintException - if there were unmatched constraints, possibly due to disconnected pattern objects
