public Predicate(@Nonnull
                 Object targetObject,
                 @Nonnull
                 String methodName,
                 @Nonnull
                 Class<?>... methodParameterClasses)

Initializes a delegate that will invoke an instance method on a class instance.

Parameters:

targetObject - The class instance on which the delegate will invoke the method.

methodName - The name of the instance method.

methodParameterClasses - The type of the parameters of the instance method.

Predicate

public Predicate(@Nonnull
                 Class<?> targetClass,
                 @Nonnull
                 String methodName,
                 @Nonnull
                 Class<?>... methodParameterClasses)

Parameters:

targetClass - The class that defines the method.

methodName - The name of the static method.

methodParameterClasses - The type of the parameters of the static method.

Method Detail

invoke

public abstract boolean invoke(T obj)

Represents a method that defines a set of criteria and determines whether the specified object meets those criteria.

Returns:

true if obj meets the criteria; otherwise, false.

test

public final boolean test(T t)

Description copied from interface: java.util.function.Predicate

Evaluates this predicate on the given argument.

Specified by:

test in interface Predicate<T>

Parameters:

t - the input argument

Returns:

true if the input argument matches the predicate, otherwise false

public static <T> Predicate<T> of(@Nonnull
                                            Predicate.Function<T> f)

Create a delegate for the given interface. This can be used to create a delegate from a lambda expression.

Parameters:

f - The function which will be invoked.

Returns:

A new delegate that will invoke the given function.

Create a delegate for the given interface. This can be used to create a delegate from a method reference to an instance method.

Parameters:

f - The function which will be invoked.

targetObject - The class instance on which the delegate will invoke the method.

methodName - The name of the instance method.

methodParameterClasses - The type of the parameters of the instance method.

Returns:
