# Package: NaturalDocs::SymbolTable
|
|
#
|
|
###############################################################################
|
|
#
|
|
# A package that handles all the gory details of managing symbols. It handles where they are defined, which files
|
|
# reference them, if any are undefined or duplicated, and loading and saving them to a file.
|
|
#
|
|
# Usage and Dependencies:
|
|
#
|
|
# - At any time, <RebuildAllIndexes()> can be called.
|
|
#
|
|
# - <NaturalDocs::Settings>, <NaturalDocs::Languages>, and <NaturalDocs::Project> must be initialized before use.
|
|
#
|
|
# - <Load()> must be called to initialize the package. At this point, the <Information Functions> will return the symbol
|
|
# table as of the last time Natural Docs was run.
|
|
#
|
|
# - Note that <Load()> and <Save()> only manage <REFERENCE_TEXT> references. All other reference types must be
|
|
# managed by their respective classes. They should be readded after <Load()> to recreate the state of the last time
|
|
# Natural Docs was run.
|
|
#
|
|
# - <Purge()> must be called, and then <NaturalDocs::Parser->ParseForInformation()> on all files that have changed so it
|
|
# can fully resolve the symbol table via the <Modification Functions>. Afterwards <PurgeResolvingInfo()> can be called
|
|
# to reclaim some memory, and the symbol table will reflect the current state of the code.
|
|
#
|
|
# - <Save()> must be called to commit any changes to the symbol table back to disk.
|
|

|
|
# prototype or summary, the UInt16 length of the string will be zero.
|
|
#
|
|
# The second stage is for references, which is analogous to <references>. Only <REFERENCE_TEXT> references are

# stored in this file, and their <Resolving Flags> are implied so they aren't stored either.
