# Lire::DlfAnalyser(3pm)

Base interface for all DLF analysers.

## NAME

Lire::DlfAnalyser - Base interface for all DLF analysers.

## SYNOPSIS

```
  use base qw/ Lire::DlfAnalyser /;
```

## DESCRIPTION

This package defines the interface that must be implemented by all DLF Analysers. All the methods defined in this package will throw a 'method not implemented' exception if they are called.

Analyser which produce DLF records for an extended schema should probably use the simpler Lire::DlfCategoriser interface.

## META INFORMATION METHODS

These methods provides information to the Lire framework about the DLF analysers.

The Lire::DlfAnalyser interface extends the Lire::Plugin interface, so they must implement all standard meta-information methods (**name()**, **title()**, **description()**).

### src\_schema()

Returns the Dlf schema which is analysed by this analyser.

E.g. `"www"`

### dst\_schema()

Returns the Dlf schema which is producted by this analyser.

E.g. `"www-user_session"`

## IMPLEMENTATION METHOD

The analyser does its job using the **analyse()** method.

### analyse( $process, $config )

The `$process` parameter contains the Lire::DlfAnalyserProcess object which is controlling the conversion process.

The `$config` parameter contains configuration data that was specified in the AnalysisJob for that converter. To register configuration specification for you DlfAnalyser, you just need to define a configuration specification under the name *analyser\_name*\_properties. This should be either a RecordSpec or ObjectSpec.
