TAP::Parser::Iterator(3pm) Perl Programmers Reference Guide
NAME
TAP::Parser::Iterator - Base class for TAP source iterators
VERSION
Version 3.44
SYNOPSIS
# to subclass: use TAP::Parser::Iterator (); use base '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.
