public Class LazyMatchingTypeIterable<T>

extends Object
implements Iterable<T>
Class Inheritance
All Implemented Interfaces
java.lang.Iterable
Type Parameters
<T>
Type of element being selected
Imports
java.util.Collections, .Iterator, .Objects
Provides a selective Iterable over values that match a specific type out of all available. The "lazy" denomination is due to the fact that the next matching value is calculated on-the-fly every time Iterator#hasNext() is called

Implements java.lang.Iterable.iterator.

Returns an iterator over elements of type T.

Returns:

Iterable whose Iterator selects only values matching the specific type

Note

the matching values are not pre-calculated (hence the "lazy" denomination) - i.e., the match is performed only when Iterator#hasNext() is called.

Parameters
<T>

The source values - ignored if null

type:Class<T>

The (never @code null) type of values to select - any value whose type is assignable to this type will be selected by the iterator.

Returns:Iterable<T>

Iterable whose Iterator selects only values matching the specific type

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
