Creates a new instance of a ValueHolder, containing the serialized values.

Parameters:

parentBtree - the parent BTree

valueSerializer - The Value's serializer

raw - The raw data containing the values

nbValues - the number of stored values

raw - the byte[] containing either the serialized array of values or the sub-btree offset

InMemoryValueHolder

InMemoryValueHolder(BTree<?,V> parentBtree,
                    V... values)

Creates a new instance of a ValueHolder, containing Values. This constructor is called when we need to create a new ValueHolder with deserialized values.

Parameters:

parentBtree - The parent BTree

values - The Values stored in the ValueHolder
