Method Detail
-
createUniqueMapping
public void createUniqueMapping(TraceLink trace)
Creates a unique trace mapping entry for the source values intrace, if applicable.- Specified by:
createUniqueMappingin classRuleImpl.UniqueState- Parameters:
trace- the trace element with source values
-
checkAndCreateUniqueMapping
public void checkAndCreateUniqueMapping(TracedRule tr, org.eclipse.emf.common.util.EList<SourceElement> ses)
Checks for existence and creates a unique trace mapping entry for the source values inses, if applicable.- Specified by:
checkAndCreateUniqueMappingin classRuleImpl.UniqueState- Parameters:
tr- the traced rule to add the unique traces toses- the source values that serve as a the unique trace key
-
matchFor
public boolean matchFor(StackFrame frame, java.lang.Object[] values)
Matches this rule againstvalues, and records a match inExecEnv.getMatches()in case of a match. In case of a unique rule, this method will not match if the rule has already matched againstvaluesbefore.- Specified by:
matchForin classRuleImpl.UniqueState- Parameters:
frame- the stack frame contextvalues- the source values to match against- Returns:
trueiff this rule matches againstvalues
-
matchFor
public boolean matchFor(StackFrame frame, java.util.Map<java.lang.String,java.lang.Object> valuesMap, java.lang.Object[] values)
Matches this rule againstvalues, and records a match inExecEnv.getMatches()in case of a match. In case of a unique rule, this method will not match if the rule has already matched againstvaluesbefore.- Specified by:
matchForin classRuleImpl.UniqueState- Parameters:
frame- the stack frame contextvaluesMap- the map of all values, including super-rule elementsvalues- the source values to match against- Returns:
trueiff this rule matches againstvalues
-
getUniqueTrace
public TraceLink getUniqueTrace(StackFrame frame, java.lang.Object[] values)
Returns the unique rule application trace forvalues, if applicable.- Overrides:
getUniqueTracein classRuleImpl.UniqueState- Parameters:
frame- the stack frame contextvalues- the source values for the trace- Returns:
- the unique rule application trace, or
null
-
applyOne
public java.lang.Object applyOne(StackFrame frame, TraceLink trace)
Applies#getRule()totrace- Overrides:
applyOnein classRuleImpl.UniqueState- Parameters:
frame- the stack frame in which to execute the applier and post-applytrace- the trace link with values to which to apply the rule- Returns:
- the rule application result
