onBacktrack

public void onBacktrack(MatchingFrame frame,
 ISearchContext context)

Description copied from interface: ISearchOperation.ISearchOperationExecutor

After the execution of the operation failed and ISearchOperation.ISearchOperationExecutor.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.

Specified by:

onBacktrack in interface ISearchOperation.ISearchOperationExecutor

execute

public boolean execute(MatchingFrame frame,
 ISearchContext context)

Specified by:

execute in interface ISearchOperation.ISearchOperationExecutor

Parameters:

frame -

context -

Returns:

true if successful, or false if backtracking needed

check

protected abstract boolean check(MatchingFrame frame,
 ISearchContext context)

Executes the checking operation
