All Implemented Interfaces:

DataOutput, ObjectOutput, AutoCloseable, Map<Object,Object>

public class LitTable
extends GeneralHashTable<Object,Object>
implements ObjectOutput

Manages the literals of a Compilation. Implements ObjectOutput, because we use externalization to determine how literals get compiled into code that re-creates the literal.

Method Details

hash

public int hash(Object key)

Description copied from class: AbstractHashTable

Calculate hash code of a key.
