Method Detail
-
createUniqueMapping
public void createUniqueMapping(TraceLink trace)
Creates a unique trace mapping entry for the source values intrace
, if applicable.- Specified by:
createUniqueMapping
in 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:
checkAndCreateUniqueMapping
in 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 againstvalues
before.- Specified by:
matchFor
in classRuleImpl.UniqueState
- Parameters:
frame
- the stack frame contextvalues
- the source values to match against- Returns:
true
iff 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 againstvalues
before.- Specified by:
matchFor
in classRuleImpl.UniqueState
- Parameters:
frame
- the stack frame contextvaluesMap
- the map of all values, including super-rule elementsvalues
- the source values to match against- Returns:
true
iff this rule matches againstvalues
-
getUniqueTrace
public TraceLink getUniqueTrace(StackFrame frame, java.lang.Object[] values)
Returns the unique rule application trace forvalues
, if applicable.- Overrides:
getUniqueTrace
in 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:
applyOne
in 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
