Interface ReadOnlyCommands.ReadOnlyPredicate

Enclosing class:

ReadOnlyCommands

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 static interface ReadOnlyCommands.ReadOnlyPredicate

A predicate to determine whether a command qualifies as Read-Only command.

Since:

6.2.4

Method Summary

Modifier and Type	Method	Description
default ReadOnlyCommands.ReadOnlyPredicate	and(ReadOnlyCommands.ReadOnlyPredicate other)	Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
boolean	isReadOnly(RedisCommand<?,?,?> command)	Evaluates this predicate on the given RedisCommand.
default ReadOnlyCommands.ReadOnlyPredicate	negate()	Returns a predicate that represents the logical negation of this predicate.
default ReadOnlyCommands.ReadOnlyPredicate	or(ReadOnlyCommands.ReadOnlyPredicate other)	Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

Method Detail

isReadOnly

boolean isReadOnly(RedisCommand<?,?,?> command)

Evaluates this predicate on the given RedisCommand.

Parameters:

command - the input command.

Returns:

true if the input argument matches the predicate, otherwise false

and

default ReadOnlyCommands.ReadOnlyPredicate and(ReadOnlyCommands.ReadOnlyPredicate other)

Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.

Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

Parameters:

other - a predicate that will be logically-ANDed with this predicate.

Returns:

a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate.

Throws:

IllegalArgumentException - if other is null.

negate

default ReadOnlyCommands.ReadOnlyPredicate negate()

Returns a predicate that represents the logical negation of this predicate.

Returns:

a predicate that represents the logical negation of this predicate.

or

default ReadOnlyCommands.ReadOnlyPredicate or(ReadOnlyCommands.ReadOnlyPredicate other)

Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.

Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

Parameters:

other - a predicate that will be logically-ORed with this predicate.

Returns:

a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate.

Throws:

IllegalArgumentException - if other is null.
