# Plucene::Analysis::Analyzer(3pm)

base class for Analyzers

## NAME

Plucene::Analysis::Analyzer - base class for Analyzers

## SYNOPSIS

```
        my $analyzer = Plucene::Analysis::Analyzer::Subclass->new;
```

## DESCRIPTION

This is an abstract base class of Analyzers.

An Analyzer builds TokenStreams, which analyze text. It thus represents  a policy for extracting index terms from text.

Typical implementations first build a Tokenizer, which breaks the stream  of characters from the Reader into raw Tokens. One or more TokenFilters  may then be applied to the output of the Tokenizer.

## METHODS

### new

```
        my $analyzer = Plucene::Analysis::Analyzer::Subclass->new;
```

### tokenstream

This must be defined in a subclass
