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

SYNOPSIS

Top

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

DESCRIPTION

Top

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;
