/**
|
|
* Interface for a Manager of Charset Converters.
|
|
*
|
|
* This Manager's data is a cache of the stuff available directly through
|
|
* Registry and Extensible String Bundles. Plus a set of convenient APIs.
|
|
*
|
|
* Note: The term "Charset" used in the classes, interfaces and file names
|
|
* should be read as "Coded Character Set". I am saying "charset" only for
|
|
* length considerations: it is a much shorter word. This convention is for
|
|
* source-code only, in the attached documents I will be either using the
|
|
* full expression or I'll specify a different convention.
|
|
*
|
|
* A DECODER converts from a random encoding into Unicode.
|
|
* An ENCODER converts from Unicode into a random encoding.
|
|
* All our data structures and APIs are divided like that.
|
|
* However, when you have a charset data, you may have 3 cases:
|
|
* a) the data is charset-dependet, but it is common for encoders and decoders
|
|
* b) the data is different for the two of them, thus needing different APIs
|
|
* and different "aProp" identifying it.
|
|
* c) the data is relevant only for one: encoder or decoder; its nature making
|
|
* the distinction.
