Base Library: Class ZSTRING
This library cluster has 40 classes.
ECF: base.ecf
Source code: directory list
An implementation of a memory compact string with the same unicode character range as the base class STRING_32 and conforming to STRING_GENERAL. ZSTRING is an alias for the actual class name EL_ZSTRING. EL_ZSTRING has many additional routines not found in STRING_32, as for example: Python like tuple substitution.

EL_ZSTRING
Usually referenced with the alias 'ZSTRING', this string is a memory efficient alternative to using STRING_32. When an application mainly uses characters from the ISO-8859-15 character set, the memory saving can be as much as 70%, while the execution efficiency is roughly the same as for STRING_8. For short strings the saving is much less: about 50%. ISO-8859-15 covers most Western european languages.

EL_EXTENDABLE_UNENCODED_CHARACTERS
Extendable unencoded characters
EL_READABLE_ZSTRING
Read only interface to class EL_ZSTRING

EL_STRING_8
String 8
EL_UNENCODED_CHARACTERS
Representation of consecutive substrings in a STRING_32 string that could not be encoded using a latin character set. The substring are held in the array unecoded: SPECIAL [CHARACTER_32] Each substring is prececded by two 32 bit characters representing the lower and upper index.
EL_UNENCODED_CHARACTERS_INDEX
Fast lookup of code in unencoded intervals array
EL_ZCODE_CONVERSION
For use with class EL_ZSTRING which redefines {READABLE_STRING_GENERAL}.code as z_code. A z_code is a hybrid of a Latin-x or Windows-x encoding and a UCS4 encoding. (We only refer to "latin" from here on)
Occassionaly a unicode character might clash with the range 0 .. 255 reserved for latin encodings. To get around this we set the sign bit to 1 to distinguish it. We can do this because the sign bit is unused in UCS4 unicode.
EL_ZSTRING_APPEND_ROUTINES
Routines for appending and prepending expanded types
EL_ZSTRING_CONVERTER
Convenience class for converting any string of type READABLE_STRING_GENERAL to type EL_ZSTRING
EL_ZSTRING_IMPLEMENTATION
Zstring implementation
EL_ZSTRING_SEARCHER
Zstring searcher
EL_ZSTRING_UNESCAPER
Z-code escape table for use with class EL_ZSTRING. See routine escape.
