Method Detail

getMarshaller

ScalarMarshaller<?> getMarshaller()

getJavaClass

default Class<? extends Object> getJavaClass()

Description copied from interface: Marshallable

Returns the type of object handled by this marshallable instance.

Specified by:

getJavaClass in interface Marshallable<Object>

Returns:

the type of object handled by this marshallable instance.

getWireType

default int getWireType()

Description copied from interface: ScalarMarshaller

Returns the wire type of the scalar value written by this marshaller.

Specified by:

getWireType in interface ScalarMarshaller<Object>

Returns:

the wire type of the scalar value written by this marshaller.

readFrom

default Object readFrom(ProtoStreamReader reader)
                 throws IOException

Description copied from interface: Marshallable

Reads an object from the specified reader.

Specified by:

readFrom in interface Marshallable<Object>

Parameters:

reader - a ProtoStream reader

Returns:

the read object

Throws:

IOException - if the object could not be read

writeTo

default void writeTo(ProtoStreamWriter writer,
                     Object value)
              throws IOException

Description copied from interface: Marshallable

Writes the specified object to the specified writer.

Specified by:

writeTo in interface Marshallable<Object>

Parameters:

writer - a ProtoStream writer

value - the object to be written

Throws:

IOException - if the object could not be written

size

default OptionalInt size(org.infinispan.protostream.ImmutableSerializationContext context,
                         Object value)

Description copied from interface: Marshallable

Predicts the size of the specified object that would be written via the Marshallable.writeTo(ProtoStreamWriter, Object) method.

Specified by:

size in interface Marshallable<Object>

Parameters:

context - a serialization context

value - the object whose size is to be determined

Returns:

the computed size of the specified object, or empty if the size could not be determined.

cast

default <T> ScalarMarshaller<T> cast(Class<T> type)
