Method Summary

Modifier and Type	Method	Description
boolean	execute(MatchingFrame frame, ISearchContext context)
ISearchOperation	getOperation()	Returns the stateless operation this executor was initialized from
void	onBacktrack(MatchingFrame frame, ISearchContext context)	After the execution of the operation failed and execute(MatchingFrame, ISearchContext) returns false, the onBacktrack callback is evaluated.
void	onInitialize(MatchingFrame frame, ISearchContext context)	During the execution of the corresponding plan, the onInitialize callback is evaluated before the execution of the operation may begin.

Method Details

getOperation

ISearchOperation getOperation()

Returns the stateless operation this executor was initialized from

onInitialize

void onInitialize(MatchingFrame frame,
 ISearchContext context)

During the execution of the corresponding plan, the onInitialize callback is evaluated before the execution of the operation may begin. Operations may use this method to initialize its internal data structures.

Throws:

InterpreterRuntimeException

onBacktrack

void onBacktrack(MatchingFrame frame,
 ISearchContext context)

After the execution of the operation failed and execute(MatchingFrame, ISearchContext) returns false, the onBacktrack callback is evaluated. Operations may use this method to clean up any temporary structures, and make the operation ready for a new execution.

Throws:

InterpreterRuntimeException

execute

boolean execute(MatchingFrame frame,
 ISearchContext context)

Parameters:

frame -

context -

Returns:

true if successful, or false if backtracking needed

Throws:

InterpreterRuntimeException
