getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: MessageReflection.MergeTarget

Returns the descriptor for the target.

public java.lang.Object getField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageReflection.MergeTarget

Obtains the value of the given field, or the default value if it is not set. For primitive fields, the boxed primitive value is returned.
