Further Information

Click on class link to see notes.

Object available via {EL_MODULE_DEFERRED_LOCALE}.Locale that allows strings in descendants of EL_MODULE_DEFERRED_LOCALE to be optionally localized at an application level by including class EL_MODULE_LOCALE from the i18n.ecf library. By default translation returns the key as a ZSTRING

Localized strings are referred to using the shorthand syntax:

Locale * "<text>"

Originally this class was introduced to prevent circular library dependencies.

EL_DEFERRED_LOCALE_IMP

Default locale implemention for unlocalized applications

EL_MODULE_DEFERRED_LOCALE

Shared access to Locale object with deferred localization implementation. See class EL_DEFERRED_LOCALE_I.

line-processing

EL_FILE_LINE_SOURCE

Interface for object that interates over the lines of an file object conforming to PLAIN_TEXT_FILE. The lines are assumed to be UTF-8 encoded by default and are converted to ZSTRING items.

Further Information

EL_LINE_SOURCE_ITERATION_CURSOR

Line source iteration cursor

EL_PLAIN_TEXT_LINE_SOURCE

Iterates over lines of a plain text file lines using either the ITERABLE or LINEAR interface. If a UTF-8 BOM is detected the encoding changes accordingly.

Further Information

EL_PLAIN_TEXT_LINE_STATE_MACHINE

A state machine for processing lines from a line source, using a line processing procedure defined by the attribute:

state: PROCEDURE [ZSTRING]

The line processing state can be changed by assigning a new procedure to state. Line processing stops either when state is assigned the procedure final or the last line in the line source is reached.
