Class WireSerializedLambda

java.lang.Object

net.openhft.chronicle.wire.WireSerializedLambda

All Implemented Interfaces:

net.openhft.chronicle.bytes.CommonMarshallable, net.openhft.chronicle.core.util.ReadResolvable, ReadMarshallable

public class WireSerializedLambda
extends Object
implements ReadMarshallable, net.openhft.chronicle.core.util.ReadResolvable

Helper class to support the serialisation of lambda expressions in Wire formats.

This allows lambdas that are Serializable to be written to and read from a Wire, preserving their capturing arguments and target functional interface method. It effectively mimics Java's built-in lambda serialisation mechanism for Chronicle Wire.

Method Detail

isSerializableLambda

public static boolean isSerializableLambda(@NotNull
                                           @NotNull Class<?> clazz)

Checks whether clazz represents a lambda class that also implements Serializable.

Parameters:

clazz - class to check

Returns:

true if clazz is a serialisable lambda

write

public static <L> void write(@NotNull
                             L lambda,
                             @NotNull
                             @NotNull ValueOut valueOut)

Writes a serialisable lambda to the supplied ValueOut.

The lambda's writeReplace method yields a SerializedLambda, which is written as a WireSerializedLambda.

Type Parameters:

L - the type of the lambda expression

Parameters:

lambda - the serialisable lambda instance

valueOut - target for the lambda's serialised form

readMarshallable

public void readMarshallable(@NotNull
                             @NotNull WireIn wire)
                      throws IllegalStateException

Deserialises this WireSerializedLambda from the given wire. All fields corresponding to SerializedLambda properties are read.

Specified by:

readMarshallable in interface ReadMarshallable

Parameters:

wire - The wire input from which the object's state should be read.

Throws:

IllegalStateException

readResolve

@NotNull
public @NotNull Object readResolve()

Recreates the original lambda instance from the deserialised state. Called after all fields have been populated via readMarshallable(WireIn).

Specified by:

readResolve in interface net.openhft.chronicle.core.util.ReadResolvable
