Method Detail

visitRule

public void visitRule(Rule rule,
                      RuntimeEnvironment<?,?> environment)

Description copied from interface: ITracer

Is called when visiting a rule starts.

Specified by:

visitRule in interface ITracer

Parameters:

rule - the rule being visited

environment - the runtime environment

visitedRule

public void visitedRule(Rule rule,
                        RuntimeEnvironment<?,?> environment,
                        java.lang.Object result)

Description copied from interface: ITracer

Is called when visiting a rule ends.

Specified by:

visitedRule in interface ITracer

Parameters:

rule - the rule being visited

environment - the runtime environment

result - the result produced by the rule

visitLoop

public void visitLoop(IEnumeratingLoop loop,
                      RuntimeEnvironment<?,?> environment)

Description copied from interface: ITracer

Is called when visiting a map starts.

Specified by:

visitLoop in interface ITracer

Parameters:

loop - the loop being visited

environment - the runtime environment

visitIteratorAssignment

public void visitIteratorAssignment(IEnumeratingLoop loop,
                                    VariableDeclaration var,
                                    java.lang.Object value)

Description copied from interface: ITracer

Is called when a loop iterator variable is assigned.

Specified by:

visitIteratorAssignment in interface ITracer

Parameters:

loop - the loop

var - the iterator variable

value - the actual value

visitedLoop

public void visitedLoop(IEnumeratingLoop loop,
                        RuntimeEnvironment<?,?> environment)

Description copied from interface: ITracer

Is called when visiting a map ends.

Specified by:

visitedLoop in interface ITracer

Parameters:

loop - the loop being visited

environment - the runtime environment

adjustSequenceForMap

public Collection<?> adjustSequenceForMap(Collection<?> collection)

Description copied from interface: ITracer

Allows a tracer to change the sequence of processing a map collection. This is intended for testing and debugging only as it normalizes and, thus, interfers with the actual execution sequence.

Specified by:

adjustSequenceForMap in interface ITracer

Parameters:

collection - the collection to be considered

Returns:

the new sequence (just the elements may be reordered)

adjustSequenceForJoin

public Collection<java.lang.Object> adjustSequenceForJoin(Collection<java.lang.Object> collection)

Description copied from interface: ITracer

Allows a tracer to change the sequence of processing a map collection. This is intended for testing and debugging only as it normalizes and, thus, interfers with the actual execution sequence.

Specified by:

adjustSequenceForJoin in interface ITracer

Parameters:

collection - the collection to be considered

Returns:

the new sequence (just the elements may be reordered)

visitSystemCall

Description copied from interface: ITracer

Is called before executing a system call.

Specified by:

visitSystemCall in interface ITracer

Parameters:

args - the arguments for the system call

visitingInstantiator

public void visitingInstantiator(java.lang.String name)

Description copied from interface: ITracer

Is called when an instantiator is being visited / executed.

Specified by:

visitingInstantiator in interface ITracer

Parameters:

name - the name of the instantiator
