All Implemented Interfaces:

InvocationHandler, net.openhft.chronicle.bytes.MethodWriterInvocationHandler

public class BinaryMethodWriterInvocationHandler
extends AbstractMethodWriterInvocationHandler

MethodWriterInvocationHandler that serialises method calls to a MarshallableOut using the binary wire format.

Each call is wrapped in a WriteDocumentContext which is opened and closed by this handler. Calls may be written as data or metadata documents depending on the metaData flag.

Constructor Detail

BinaryMethodWriterInvocationHandler

public BinaryMethodWriterInvocationHandler(Class<?> tClass,
                                           boolean metaData,
                                           Supplier<MarshallableOut> marshallableOutSupplier)

Create a handler using the given class, metadata flag and a supplier of MarshallableOut.

Parameters:

tClass - primary interface of the proxy

metaData - Flag to determine if metadata is to be written.

marshallableOutSupplier - supplier of the destination for serialised calls

Method Detail

doInvoke

protected Object doInvoke(Object proxy,
                          Method method,
                          Object[] args)

Intercepts calls on the proxy. A call to writingDocument() is handled here to expose the underlying WriteDocumentContext directly. Other calls are delegated to AbstractMethodWriterInvocationHandler.doInvoke(Object, Method, Object[]).

Overrides:

doInvoke in class AbstractMethodWriterInvocationHandler

metaData

public boolean metaData()

Gets the current metadata setting for this handler.

Returns:

true if metadata is enabled, false otherwise.

handleInvoke

protected void handleInvoke(Method method,
                            Object[] args)

Serialises the given method call with args to the configured output. Each invocation acquires a new WriteDocumentContext which is marked to possibly hold metadata according to metaData. If the return type of the method is an interface the document context is marked as chained so subsequent calls may share the same context.

Specified by:

handleInvoke in class AbstractMethodWriterInvocationHandler

Parameters:

method - The method being invoked.

args - Arguments provided for the method invocation.
