org.python.core.PyObject
org.python.modules._codecs.EncodingMap
- All Implemented Interfaces:
Serializable
- Enclosing class:
- _codecs
Optimized charmap encoder mapping.
Uses a trie structure instead of a dictionary; the speedup primarily comes from not creating
integer objects in the process. The trie is created by inverting the encoding map.

- an encoder mapping
-
lookup
public int lookup(char c) Lookup a char in the EncodingMap.- Parameters:
c
- a char- Returns:
- an int, -1 for failure
