Interface CMethodSet.Strategy

All Known Implementing Classes:

CClass.NoDupStrategy

Enclosing interface:

CMethodSet

public static interface CMethodSet.Strategy

Represents the interface for strategies used in accumulating method sets. Typically a client of CMethodSet will create an anonymous class of type Strategy that is passed to accumMethodSet for adding some subset of the methods of the CMethodSet to an accumulator.

See Also:

CMethodSet#accumMethodSet(CMethodSet.Strategy,String,CMethodSet)

Field Summary
static byte	DONE_WITH_ACCUM           The bit mask representing that no more checks of the candidate method need to be made against the accumulator by calls to resultFor().
static byte	IGNORE_CURRENT           The bit mask representing that the candidate method passed to resultFor() should be ignored.
static byte	REMOVE_ACCUM           The bit mask representing that the accumMethod method passed to resultFor() should be removed from the accumulator.

 

Method Summary
boolean	maybeInclude(CMethod candidate, CClassType[] args)           Indicates whether the given candidate method should be checked against the methods already in the accumulator for possible inclusion in the accumulator.
byte	resultFor(CMethod candidate, CMethod accumMethod)           Checks the given candidate method against a single method in the accumulator and decides whether the candidate should be added to the accumulator, whether the method from the accumulator should be removed, and whether additional checks against the remaining methods in the accumulator are necessary.

 

Field Detail

IGNORE_CURRENT

public static final byte IGNORE_CURRENT

The bit mask representing that the candidate method passed to resultFor() should be ignored.

See Also:

resultFor(CMethod,CMethod)

REMOVE_ACCUM

public static final byte REMOVE_ACCUM

The bit mask representing that the accumMethod method passed to resultFor() should be removed from the accumulator.

See Also:

resultFor(CMethod,CMethod)

DONE_WITH_ACCUM

public static final byte DONE_WITH_ACCUM

The bit mask representing that no more checks of the candidate method need to be made against the accumulator by calls to resultFor().

resultFor(CMethod,CMethod)

maybeInclude

public boolean maybeInclude(CMethod candidate,
                            CClassType[] args)
                              throws UnpositionedError

Indicates whether the given candidate method should be checked against the methods already in the accumulator for possible inclusion in the accumulator.

Parameters:

candidate - the candidate method for inclusion in the accumulator

Returns:

true if the method should be considered

Throws:

UnpositionedError - usually the implementer will want to use CContextType.reportTrouble() for error reporting to avoid throwing an exception, the exception is allowed here for flexibility

resultFor

public byte resultFor(CMethod candidate,
                      CMethod accumMethod)
                        throws UnpositionedError

Checks the given candidate method against a single method in the accumulator and decides whether the candidate should be added to the accumulator, whether the method from the accumulator should be removed, and whether additional checks against the remaining methods in the accumulator are necessary.

Parameters:

candidate - the candidate method for inclusion in the accumulator

accumMethod - a single method from the accumulator

Returns:

a bit mask indicating the actions to be taken

Throws:

UnpositionedError - if a problem is detected in the source code.
