NAME
TM::Serializable - Topic Maps, abstract trait for stream (map) based input/output driversSYNOPSIS
# step 1) you write an input/output driver for a serialized TM format package MyFormat;
# provides methods sub deserialize { my $self = shift; # gets current map my $stream = shift; # .... fill the map with content }
sub serialize { my $self = shift; # get the map # .... return ... #serialized content } 1;
# step 2) construct a subclass of TM using this driver package MapWithMyFormat;
use TM; use base qw(TM); use Class::Trait qw(TM::Serializable MyFormat);
1;
# step 3) use it in your application my $tm = new MapWithMyFormat (url => 'file:map.myformat'); $tm->sync_in; # uses MyFormat to parse the content from the file
DESCRIPTION
This trait implements synchronizable resources using a serialized format. Examples are formats such as AsTMa 1.0, 2.0, LTM, CTM, XTM. The only thing these drivers have to provide are the methods "serialize" and "deserialize" which serialize maps to streams and vice-versa.This trait provides the implementations for "source_in" and "source_out" triggering "deserialize" and "serialize", respectively.
INTERFACE
Methods
- source_in
- Uses the URL attached to the map object to trigger "deserialize" on the stream content behind the resource. All URLs of LWP are supported. If the URI is "io:stdio" then content from STDIN is consumed. This content can be consumed more than once (it is buffered internally), so that you can read several times from "io:stdin" getting the same input.
If the resource URI is "io:stdout", then nothing happens.
If the resource URI is "null:", then nothing happens.
- source_out
- This method triggers "serialize" on the object. The contents will be copied to the resource identified by the URI attached to the object. At the moment, only "file:" URLs and "io:stdout" is supported.
If the resource URI is "io:stdin", nothing happens.
If the resource URI is "null:", nothing happens.
If the resource URI is "inline:.." nothing happens.
