Method Detail

readFrom

public T readFrom(ProtoStreamReader reader)
           throws IOException

Description copied from interface: Marshallable

Reads an object from the specified reader.

Specified by:

readFrom in interface Marshallable<T>

Parameters:

reader - a ProtoStream reader

Returns:

the read object

Throws:

IOException - if the object could not be read

writeTo

public void writeTo(ProtoStreamWriter writer,
                    T object)
             throws IOException

Description copied from interface: Marshallable

Writes the specified object to the specified writer.

Specified by:

writeTo in interface Marshallable<T>

Parameters:

writer - a ProtoStream writer

object - the object to be written

Throws:

IOException - if the object could not be written

size

public OptionalInt size(org.infinispan.protostream.ImmutableSerializationContext context,
                        T object)

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<T>

Parameters:

context - a serialization context

object - 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.

getJavaClass

public Class<? extends T> getJavaClass()

Description copied from interface: Marshallable

Returns the type of object handled by this marshallable instance.

Specified by:

getJavaClass in interface org.infinispan.protostream.BaseMarshaller<T>

Specified by:

getJavaClass in interface Marshallable<T>

Returns:

the type of object handled by this marshallable instance.
