  org.hd.d.pg2k.svrCore.Compact7BitString.WordChars

Enclosing class:: Compact7BitString

private static final class Compact7BitString.WordChars
extends java.lang.Object
extends java.lang.Object

Boolean true/false flags for what are considered "word" chars; initialised on first use. Also holds intern()ed one-byte Strings for each token to avoid run-time allocation similar in intent to Integer.valueOf(int).

The word characters are [a-zA-Z_0-9]. The non-word characters are everything else in the [0,127] 7-bit-ASCII alphabet.

These tokens need not be strictly alternating provided thst ambiguity can be avoided.

These tokens are currently not limited in length.

Inspired by the HuffWord compression tokeniser from "Managing Gigabytes".
