Interface IConstantCollection.IConstantIterator

All Known Implementing Classes:

ConstantCollection.ConstantIterator

Enclosing interface:

IConstantCollection

public static interface IConstantCollection.IConstantIterator

A custom fail-fast iterator class returned by IConstantCollection.iterator(). It allows iterating over all entries in a way that steps over all 'invalid' inner slots (extra slots consumed by CONSTANT_Long and CONSTANT_Double entries).

Method Summary

CONSTANT_info	nextConstant() Returns the next entry.
int	nextIndex() Returns the next entry slot index.
CONSTANT_info	set(CONSTANT_info constant) 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.

Method Detail

nextIndex

int nextIndex()

Returns the next entry slot index.

Returns:

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

nextConstant

CONSTANT_info nextConstant()

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

Returns:

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

set

CONSTANT_info set(CONSTANT_info constant)

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.
