write_impl

public final AutoBuffer write_impl(AutoBuffer ab)

init

protected abstract java.util.Map<K,V> init()

writeable

protected boolean writeable()

Can the map be modified? By default we don't make any assumptions about the implementation of the backing Map and we will write-lock the map when we are trying to serialize it. However, if the specific implementation knows it is safe to modify the map when it is being written, it can bypass the write-lock by overriding this method.

Returns:

true if map can be modified

writeMap

protected void writeMap(AutoBuffer ab,
                        byte mode)

writeKey

protected void writeKey(AutoBuffer ab,
                        IcedHashMapBase.KeyType keyType,
                        K key)

writeValue

protected void writeValue(AutoBuffer ab,
                          IcedHashMapBase.ValueType valueType,
                          IcedHashMapBase.ArrayType arrayType,
                          V value)

readKey

protected K readKey(AutoBuffer ab,
                    IcedHashMapBase.KeyType keyType)

readValue

protected V readValue(AutoBuffer ab,
                      IcedHashMapBase.ValueType valueType,
                      IcedHashMapBase.ArrayType arrayType)

read_impl

Parameters:

ab - Contains the serialized K-V pairs
