Attean::API::AtOnceParser(3)
Role for parsers that natively parse all input before returning any data
VERSION
This document describes Attean::API::AtOnceParser version 0.017
DESCRIPTION
The Attean::API::AtOnceParser role defines parsers that must parse all input
data before any objects are constructed and returned or passed to callback
functions. This role adds methods that builds on this functionality to allow
parsing data using different approaches.
ROLES
This role consumes the Attean::API::Parser role.
REQUIRED METHODS
Classes consuming this role must provide the following methods:
- "parse_list_from_io( $fh )"
-
Returns a list of all objects that result from parsing the data read from the
IO::Handle object $fh.
- "parse_list_from_bytes( $data )"
-
Returns a list of all objects that result from parsing the data read from the
UTF-8 encoded byte string $data.
METHODS
This role provides default implementations of the following methods:
- "parse_iter_from_io( $fh )"
-
Returns an Attean::API::Iterator that result from parsing the data read from
the IO::Handle object $fh.
- "parse_iter_from_bytes( $data )"
-
Returns an Attean::API::Iterator that result from parsing the data read from
the UTF-8 encoded byte string $data.
- "parse_cb_from_io( $fh )"
-
Calls the "$parser->handler" function once for each object that result
from parsing the data read from the IO::Handle object $fh.
- "parse_cb_from_bytes( $data )"
-
Calls the "$parser->handler" function once for each object that result
from parsing the data read from the UTF-8 encoded byte string $data.
