DoublePredicate (Java Platform SE 8 b92)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface DoublePredicate
```
Determines if the double input value matches some criteria. This is the double-consuming primitive type specialization of Predicate.

Since:

1.8

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`default DoublePredicate`	`and(DoublePredicate p)` Returns a predicate which evaluates to `true` only if this predicate and the provided predicate both evaluate to `true`.
`default DoublePredicate`	`negate()` Returns a predicate which negates the result of this predicate.
`default DoublePredicate`	`or(DoublePredicate p)` Returns a predicate which evaluates to `true` if either this predicate or the provided predicate evaluates to `true`.
`boolean`	`test(double value)` Returns `true` if the input value matches some criteria.
`default DoublePredicate`	`xor(DoublePredicate p)` Returns a predicate that evaluates to `true` if both or neither of the component predicates evaluate to `true`.

- Method Detail
  - test
```
boolean test(double value)
```
    Returns true if the input value matches some criteria.
    
    Parameters:
    
    value - the value to be tested.
    
    Returns:
    
    true if the input value matches some criteria, otherwise false.
  - and
```
default DoublePredicate and(DoublePredicate p)
```
    Returns a predicate which evaluates to true only if this predicate and the provided predicate both evaluate to true. If this predicate returns false then the remaining predicate is not evaluated.
    
    Parameters:
    
    p - a predicate which will be logically-ANDed with this predicate.
    
    Returns:
    
    a new predicate which returns true only if both predicates return true.
  - negate
```
default DoublePredicate negate()
```
    Returns a predicate which negates the result of this predicate.
    
    Returns:
    
    a new predicate who's result is always the opposite of this predicate.
  - or
```
default DoublePredicate or(DoublePredicate p)
```
    Returns a predicate which evaluates to true if either this predicate or the provided predicate evaluates to true. If this predicate returns true then the remaining predicate is not evaluated.
    
    Parameters:
    
    p - a predicate which will be logically-ANDed with this predicate.
    
    Returns:
    
    a new predicate which returns true if either predicate returns true.
  - xor
```
default DoublePredicate xor(DoublePredicate p)
```
    Returns a predicate that evaluates to true if both or neither of the component predicates evaluate to true.
    
    Parameters:
    
    p - a predicate which will be logically-XORed with this predicate.
    
    Returns:
    
    a predicate that evaluates to true if all or none of the component predicates evaluate to true.
