Class SimpleFeatureRealizer

java.lang.Object
  org.biojava.bio.seq.SimpleFeatureRealizer

All Implemented Interfaces:

Serializable, FeatureRealizer

public class SimpleFeatureRealizer
extends Object
implements FeatureRealizer, Serializable

FeatureRealizer which uses a lookup table to map template classes to implementations. Optionally, this implementation can fall back on another FeatureRealizer if it fails.

When searching for a Feature implementation to match a specific Feature.Template class, the following search order is used:

1. Mappings added to this SimpleFeatureRealizer, in reverse order of addition.
2. Any mappings known to the fallback realizer, if one is installed.
3. If no mapping can be found, a BioException is thrown.

Method Detail

addImplementation

public void addImplementation(Class template,
                              Class impl)
                       throws BioException

Install a new mapping from a class of Feature.Template to a class of Feature implementations. The implementation class MUST have a public constructor of the form (Sequence, FeatureHolder, Feature.Template).

A newly added implementation takes precendence over any existing implementations if a template can be realized by more than one implementation.

Parameters:

template - The class of templates to implement.

impl - A class of Feature which can be used to implement these templates.

Throws:

BioException

realizeFeature

public Feature realizeFeature(Sequence seq,
                              FeatureHolder parent,
                              Feature.Template temp)
                       throws BioException

Description copied from interface: FeatureRealizer

Install a feature on the specified sequence.

Specified by:

realizeFeature in interface FeatureRealizer

Parameters:

seq - The sequence to which the feature will be added.

parent - The FeatureHolder which is to be the Feature's immediate parent.

temp - A description of the desired feature.

Returns:

A newly constructed feature, to be added to the sequence.

Throws:

BioException - If the feature could not be constructed.
