NAME

       TAP::Parser::Iterator::Array - Iterator for array-based TAP sources

VERSION

       Version 3.28

SYNOPSIS

	 use TAP::Parser::Iterator::Array;
	 my @data = ('foo', 'bar', baz');
	 my $it   = TAP::Parser::Iterator::Array->new(@data);
	 my $line = $it->next;

DESCRIPTION

       This is a simple iterator wrapper for arrays of scalar content, used by TAP::Parser.  Unless you're writing a plugin or subclassing, you
       probably won't need to use this module directly.

METHODS

   Class Methods
       "new"

       Create an iterator.  Takes one argument: an $array_ref

   Instance Methods
       "next"

       Iterate through it, of course.

       "next_raw"

       Iterate raw input without applying any fixes for quirky input syntax.

       "wait"

       Get the wait status for this iterator. For an array iterator this will always be zero.

       "exit"

       Get the exit status for this iterator. For an array iterator this will always be zero.

NAME

       TAP::Parser::Iterator - Base class for TAP source iterators

VERSION

       Version 3.25

SYNOPSIS

	 # to subclass:
	 use vars qw(@ISA);
	 use TAP::Parser::Iterator ();
	 @ISA = qw(TAP::Parser::Iterator);
	 sub _initialize {
	   # see TAP::Object...
	 }

	 sub next_raw { ... }
	 sub wait     { ... }
	 sub exit     { ... }

DESCRIPTION

       This is a simple iterator base class that defines TAP::Parser's iterator API.  Iterators are typically created from
       TAP::Parser::SourceHandlers.

METHODS

   Class Methods
       "new"

       Create an iterator.  Provided by TAP::Object.

   Instance Methods
       "next"

	while ( my $item = $iter->next ) { ... }

       Iterate through it, of course.

       "next_raw"

       Note: this method is abstract and should be overridden.

	while ( my $item = $iter->next_raw ) { ... }

       Iterate raw input without applying any fixes for quirky input syntax.

       "handle_unicode"

       If necessary switch the input stream to handle unicode. This only has any effect for I/O handle based streams.

       The default implementation does nothing.

       "get_select_handles"

       Return a list of filehandles that may be used upstream in a select() call to signal that this Iterator is ready. Iterators that are not
       handle-based should return an empty list.

       The default implementation does nothing.

       "wait"

       Note: this method is abstract and should be overridden.

	my $wait_status = $iter->wait;

       Return the "wait" status for this iterator.

       "exit"

       Note: this method is abstract and should be overridden.

	my $wait_status = $iter->exit;

       Return the "exit" status for this iterator.

SUBCLASSING

       Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.

       You must override the abstract methods as noted above.

   Example
       TAP::Parser::Iterator::Array is probably the easiest example to follow.	There's not much point repeating it here.
