Method Detail

write

public final void write(Output output,
                        java.lang.Object object)

Specified by:

write in class FieldSerializer.CachedField

read

public final void read(Input input,
                       java.lang.Object object)

Specified by:

read in class FieldSerializer.CachedField

readSlow

private void readSlow(Input input,
                      java.lang.Object object)

This is a fall-back solution for the case that bulk reading of bytes into object memory is not supported. Unfortunately, current Oracle JDKs do not allow for bulk reading in this style due to problems with GC.

Parameters:

public void copy(java.lang.Object original,
                 java.lang.Object copy)
