CacheObjectByteArrayImpl

public CacheObjectByteArrayImpl(byte[] val)

Parameters:

val - Value.

Method Detail

finishUnmarshal

public void finishUnmarshal(CacheObjectContext ctx,
                   ClassLoader ldr)
                     throws IgniteCheckedException

Specified by:

finishUnmarshal in interface CacheObject

Parameters:

ctx - Context.

ldr - Class loader.

Throws:

IgniteCheckedException - If failed.

value

@Nullable
public <T> T value(CacheObjectContext ctx,
                   boolean cpy)

Specified by:

value in interface CacheObject

Parameters:

ctx - Context.
