Method Summary

Modifier and Type	Method and Description
static <T extends Diffable<T>> T	assertDiffApplication(T remoteChanges, T localInstance, Diff<T> diffs) Asserts that changes are applied correctly, i.e.
static <T extends Writeable> T	assertSerialization(T testInstance, NamedWriteableRegistry namedWriteableRegistry, Writeable.Reader<T> reader) Asserts that testInstance can be correctly.
static <T extends Writeable> T	copyInstance(T diffs, NamedWriteableRegistry namedWriteableRegistry, Writeable.Reader<T> reader) Simulates sending diffs over the wire
static <T extends Diffable<T>> void	testDiffableSerialization(java.util.function.Supplier<T> testInstance, java.util.function.Function<T,T> modifier, NamedWriteableRegistry namedWriteableRegistry, Writeable.Reader<T> reader, Writeable.Reader<Diff<T>> diffReader) Tests making random changes to an object, calculating diffs for these changes, sending this diffs over the wire and appling these diffs on the other side.

Method Detail

assertDiffApplication

public static <T extends Diffable<T>> T assertDiffApplication(T remoteChanges,
                                                              T localInstance,
                                                              Diff<T> diffs)

Asserts that changes are applied correctly, i.e. that applying diffs to localInstance produces that object equal but not the same as the remoteChanges instance.

copyInstance

public static <T extends Writeable> T copyInstance(T diffs,
                                                   NamedWriteableRegistry namedWriteableRegistry,
                                                   Writeable.Reader<T> reader)
                                            throws java.io.IOException

Simulates sending diffs over the wire

Throws:

java.io.IOException

testDiffableSerialization

public static <T extends Diffable<T>> void testDiffableSerialization(java.util.function.Supplier<T> testInstance,
                                                                     java.util.function.Function<T,T> modifier,
                                                                     NamedWriteableRegistry namedWriteableRegistry,
                                                                     Writeable.Reader<T> reader,
                                                                     Writeable.Reader<Diff<T>> diffReader)
                                                              throws java.io.IOException

Tests making random changes to an object, calculating diffs for these changes, sending this diffs over the wire and appling these diffs on the other side.

Throws:

java.io.IOException

assertSerialization

public static <T extends Writeable> T assertSerialization(T testInstance,
                                                          NamedWriteableRegistry namedWriteableRegistry,
                                                          Writeable.Reader<T> reader)
                                                   throws java.io.IOException

Asserts that testInstance can be correctly.

Throws:

java.io.IOException
