# File: DualIndexHashObject.pm
|
|
#
|
|
# Purpose: Provides a hash-table object with an abstracted API that includes
|
|
# setting and deleting values, saving to and loading from files, etc.
|
|
#
|
|
# DualIndexHashObject extends the HashObject with an additional index key.
|
|
# Provides case-insensitive access to both index keys, while preserving
|
|
# original case when displaying the keys.
|
|
#
|
|
# Data is stored in working memory for lightning fast performance. If you have
|
|
# a huge amount of data, consider using DualIndexSQLiteObject instead.
|
|
#
|
|
# If a filename is provided, data is written to the file after any modifications.
