Class AccessorGetIterator<T>

java.lang.Object

com.massa.mrules.util.iterate.AccessorGetIterator<T>

Type Parameters:

T - target type.

All Implemented Interfaces:

Iterator<T>

Direct Known Subclasses:

MArithmeticAccessor.InternalIterator

public class AccessorGetIterator<T>
extends Object
implements Iterator<T>

Allows to iterate over an Iterator of Objects, to convert it into an Iterator on the provided Accessor get result on these Objects.
Meaning that a sub context will be created to have the Objects as read base.
Providing a target class allows to perform dynamic Cast on elements if necessary.
Providing a null iterator will result in a behavior equivalent to the CastIterator.
