public class CMethodSet

extends CAbstractMethodSet

implements Constants

This class encapsulates a collection of method signatures. It is used to track the type signatures of methods declared in a class and to track the apparent methods of a class as augmented by external methods and as viewed by another compilation unit. It includes facilities for accumulating sets of methods that meet some specified criteria, for example, methods that are specialized by a given method.

Field Detail

MIN_HASH_SIZE

private static int MIN_HASH_SIZE

The minimum size of the collection for which a Hashset will be instantiated to track method identifiers.

methodIdents

private Set methodIdents

A set of the identifiers of methods present in this collection. This is used for efficient lookup; a linear search of methodArray is only performed if this set indicates that the search will be successful. The search is still needed since many lookup operations will yield sets of applicable methods. Also note that for small collections this set is just left as null as it is more efficient in those cases to just perform the linear search.

NO_TOKEN

private static final TokenReference NO_TOKEN

CMethodSet

public CMethodSet(CMethod[] methodArray)

CMethodSet

public CMethodSet()

accumMethodSet

public void accumMethodSet(CMethodSet.Strategy actor,
                           String ident,
                           CMethodSet accum,
                           CClassType[] args)
                    throws UnpositionedError

Processes the methods in this set using the given strategy and mutates the accumulator according to the strategy. Examples of the use of this method can be found in CClass.

Parameters:

actor - the strategy used for selecting methods

ident - the identifier of the methods to be selected, used in an efficiency hack for avoiding a linear search in cases where such a search is certain to fail

accum - an accumulator for the result, is mutated

Throws:

UnpositionedError - at the discretion of the strategy

makeResult

public static byte makeResult(boolean ignoreCurrent,
                              boolean remove,
                              boolean done)

Constructs a bit-mask for implementers of the resultFor() method of Strategy.
