All Superinterfaces:

<T>

All Known Implementing Classes:

BloomFilter, CharMatcher, Range

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@GwtCompatible
public interface Predicate<T>
extends <T>
```
Legacy version of . Determines a true or false value for a given input.
As this interface extends java.util.function.Predicate, an instance of this type may be used as a Predicate directly. To use a java.util.function.Predicate where a com.google.common.base.Predicate is expected, use the method reference predicate::test.
This interface is now a legacy type. Use java.util.function.Predicate (or the appropriate primitive specialization such as IntPredicate) instead whenever possible. Otherwise, at least reduce explicit dependencies on this type by using lambda expressions or method references instead of classes, leaving your code easier to migrate in the future.
The Predicates class provides common predicates and related utilities.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`boolean`	`T input)`	Returns the result of applying this predicate to `input` (Java 8 users, see notes in the class documentation above).
`boolean`	`object)`	Indicates whether another object is equal to this predicate.
`default boolean`	`T input)`	Evaluates this predicate on the given argument.

  - apply
```
boolean  T input)
```
    Returns the result of applying this predicate to input (Java 8 users, see notes in the class documentation above). This method is generally expected, but not absolutely required, to have the following properties:
    
    Its execution does not cause any observable side effects.
    The computation is consistent with equals; that is, Objects.equal(a, b) implies that predicate.apply(a) == predicate.apply(b)).
    Throws:
    
    - if input is null and this predicate does not accept null arguments
  - equals
```
boolean   object)
```
    Indicates whether another object is equal to this predicate.
    Most implementations will have no reason to override the behavior of . However, an implementation may also choose to return true whenever object is a Predicate that it considers interchangeable with this one. "Interchangeable" typically means that this.apply(t) == that.apply(t) for all t of type T). Note that a false result from this method does not imply that the predicates are known not to be interchangeable.
    
    Overrides:
    
    in class
    
    Parameters:
    
    object - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.
