.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A \s-1TAP \s0\fIsource\fR is something that produces a stream of \s-1TAP\s0 for the parser to
consume, such as an executable file, a text file, an archive, an \s-1IO\s0 handle, a
database, etc. \f(CW\*(C`TAP::Parser::Source\*(C'\fRs encapsulate these \fIraw\fR sources, and
provide some useful meta data about them. They are used by
TAP::Parser::SourceHandlers, which do whatever is required to produce &
capture a stream of \s-1TAP\s0 from the \fIraw\fR source, and package it up in a
TAP::Parser::Iterator for the parser to consume.
.PP
Unless you're writing a new TAP::Parser::SourceHandler, a plugin or
subclassing TAP::Parser, you probably won't need to use this module directly.

Chaining getter/setter for the raw \s-1TAP\s0 source. This is a reference, as it may
contain large amounts of data (eg: raw \s-1TAP\s0).

Chaining getter/setter for meta data about the source. This defaults to an
empty hashref. See \*(L"assemble_meta\*(R" for more info.

Chaining getter/setter for the source's configuration, if any has been provided
by the user. How it's used is up to you. This defaults to an empty hashref.

Gathers meta data about the \*(L"raw\*(R" source, stashes it in \*(L"meta\*(R" and returns
it as a hashref. This is done so that the TAP::Parser::SourceHandlers don't
have to repeat common checks. Currently this includes:
