# Bio::Annotation::Target(3pm)

Provides an object which represents a target (ie, a similarity hit) from one object to something in another database

## NAME

Bio::Annotation::Target - Provides an object which represents a target (ie, a similarity hit) from one object to something in another database

## SYNOPSIS

```
   $target1 = Bio::Annotation::Target->new(-target_id  => 'F321966.1',
                                          -start      => 1,
                                          -end        => 200,
                                          -strand     => 1,   # or -1
                                         );
   # or
   $target2 = Bio::Annotation::Target->new();
   $target2->target_id('Q75IM5');
   $target2->start(7);
   # ... etc ...
   # Target is-a Bio::AnnotationI object, can be added to annotation
   # collections, e.g. the one on features or seqs
   $feat->annotation->add_Annotation('Target', $target2);
```

## DESCRIPTION

## APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a \_

## AnnotationI implementing functions

### as\_text

```
 Title   : as_text
 Usage   :
 Function:
 Example :
 Returns :
 Args    :
```

### display\_text

```
 Title   : display_text
 Usage   : my $str = $ann->display_text();
 Function: returns a string. Unlike as_text(), this method returns a string
           formatted as would be expected for te specific implementation.
           One can pass a callback as an argument which allows custom text
           generation; the callback is passed the current instance and any text
           returned
 Example :
 Returns : a string
 Args    : [optional] callback
```

### tagname

```
 Title   : tagname
 Usage   : $obj->tagname($newval)
 Function: Get/set the tagname for this annotation value.
           Setting this is optional. If set, it obviates the need to
           provide a tag to Bio::AnnotationCollectionI when adding
           this object. When obtaining an AnnotationI object from the
           collection, the collection will set the value to the tag
           under which it was stored unless the object has a tag
           stored already.
 Example :
 Returns : value of tagname (a scalar)
 Args    : new value (a scalar, optional)
```

## Specific accessors for Targets

### target\_id

- Usage

  ```
    $obj->target_id()        #get existing value
    $obj->target_id($newval) #set new value
  ```

- Function

  - Returns

  value of target\_id (a scalar)

- Arguments

  new value of target\_id (to set)
