NAME

RPC::XML::ParserFactory - A factory class for RPC::XML::Parser objects

SYNOPSIS

    use RPC::XML::ParserFactory;
    ...
    $P = RPC::XML::ParserFactory->new();
    $P->parse($message);

DESCRIPTION

The RPC::XML::ParserFactory class encapsulates the process of creating parser objects that adhere to the interface described in RPC::XML::Parser. Under the hood, the parser object created and returned could be from any of a number of implementation classes.

IMPORT-TIME ARGUMENTS

You can specify a particular underlying parser class to use, if you do not want RPC::XML::ParserFactory to use the default class. This is done with the "class" keyword:

    use RPC::XML::ParserFactory (class => 'XML::Parser');

The value may be the name for any of the built-in classes, or it may be the name of a class that inherits from RPC::XML::Parser (and can thus be "manufactured" by the factory). The value is saved and becomes the default class for any calls to new that do not explicitly name a class to use.

Note that if the specified class is not valid, this is not tested until the first call to new, at which point an invalid class will cause an exception (error) to occur. The constructor will return "undef" and the $RPC::XML::ERROR variable will contain the error message.

Names of Built-In Parsers

The following names are valid when specified as the value of the "class" argument described above:

All of these specify the parser implementation based on the XML::Parser module. This is the default parser if the user does not specify any alternative.
These specify a parser implementation based on the XML::LibXML module. This is a new parser and not as well-vetted as the previous one, hence it must be explicitly requested.

SUBROUTINES/METHODS

The methods are:

Create a new instance of the class. Any extra data passed to the constructor is taken as key/value pairs (not a hash reference) and attached to the object.

This method passes all arguments on to the new() method of the chosen implementation class, except for the following:

If the user chooses, they may specify an explicit class to use for parsers when calling new(). If passed, this overrides any value that was given at use-time (processed by import()).

DIAGNOSTICS

The constructor returns "undef" upon failure, with the error message available in the global variable $RPC::XML::ERROR.
