# TM::Index::Characteristics(3pm)

Topic Maps, Indexing support (match layer)

## NAME

TM::Index::Characteristics - Topic Maps, Indexing support (match layer)

## SYNOPSIS

```
    # somehow get a map (any subclass of TM will do)
    my $tm = ...
    # one option: create a lazy index which learns as you go
    use TM::Index::Characteristics;
    my $idx = new TM::Index::Characteristics ($tm);

    # for most operations which involve match_forall to be called
    # for querying characteristics should be much faster
```

## DESCRIPTION

This index can be attached to a map if querying it for characteristics (here names and occurrences) is intensive.

The package inherits most of its functionality from TM::Index.

## INTERFACE

### Constructor

The constructor/destructor is inherited from TM::Index.

### Methods

## SEE ALSO

TM, TM::Index
