<T>
Type of iterated element
Imports

An Iterator that selects only objects of a certain type from the underlying available ones. The "lazy" denomination is due to the fact that selection occurs only when hasNext() is called

public boolean
hasNext()

Implements java.util.Iterator.hasNext.

Returns true if the iteration has more elements.

public static <

Returns:

An Iterator whose next() call 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.

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Returns:boolean

Parameters
<T>
Type if iterated element
values:Iterator<?>

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:Iterator<T>

An Iterator whose next() call selects only values matching the specific type

Note

Returns the next element in the iteration.

Returns:T

the next element in the iteration

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
