- All Implemented Interfaces:
    Marshaller
  Direct Known Subclasses:
    AbstractNodeNameAwareMarshaller

      public abstract class AbstractMarshaller
      extends Object
      implements Marshaller

  Base class for marshallers. Provides default implementations of methods that work with byte array or `GridByteArrayList`. These implementations use `GridByteArrayInputStream` or `GridByteArrayOutputStream` to marshal and unmarshal objects.

    - #### ctx

          protected MarshallerContext ctx

      Context.

  - ### Constructor Detail

    - #### AbstractMarshaller

          public AbstractMarshaller()

  - ### Method Detail

    - #### onUndeploy

          public abstract void onUndeploy(ClassLoader ldr)

      Undeployment callback invoked when class loader is being undeployed. Some marshallers may want to clean their internal state that uses the undeployed class loader somehow.
      Parameters:
        `ldr` - Class loader being undeployed.

    - #### getContext

          public MarshallerContext getContext()

      Returns:
        Marshaller context.

    - #### setContext

          public void setContext(MarshallerContext ctx)

      Sets marshaller context.
      Specified by:
        `setContext` in interface `Marshaller`
      Parameters:
        `ctx` - Marshaller context.
