Method Detail

nextIndex

public int nextIndex()

Description copied from interface: IConstantCollection.IConstantIterator

Returns the next entry slot index.

Specified by:

nextIndex in interface IConstantCollection.IConstantIterator

Returns:

int next valid slot index [always positive for a valid slot; -1 when the enumeration is exhausted]

nextConstant

public CONSTANT_info nextConstant()

Description copied from interface: IConstantCollection.IConstantIterator

Returns the next entry. This is a convenience method for doing get(nextIndex()) and avoiding index bound violation exceptions.

Specified by:

nextConstant in interface IConstantCollection.IConstantIterator

Returns:

CONSTANT_info next valid entry [null when the enumeration is exhausted]

set

public CONSTANT_info set(CONSTANT_info constant)

Description copied from interface: IConstantCollection.IConstantIterator

A convenience method that is equivalent to IConstantCollection.set(int, com.vladium.jcd.cls.constant.CONSTANT_info) and replaces the entry that was visited last without invalidating the iterator.

Specified by:

set in interface IConstantCollection.IConstantIterator

shift

private void shift()
