                             ChangeVetoException

Create a new Feature, and add it to this FeatureHolder. This method will generally only work on Sequences, and on some Features which have been attached to Sequences.

Specified by:

createFeature in interface FeatureHolder

Throws:

BioException - if something went wrong during creating the feature

ChangeVetoException - if this FeatureHolder does not support creation of new features, or if the change was vetoed

features

public Iterator features()

Iterate over any child features which are held by this feature. The order of iteration MAY be significant for some types of Feature.

Specified by:

features in interface Feature

Specified by:

features in interface FeatureHolder

Returns:

an Iterator

filter

public FeatureHolder filter(FeatureFilter filter)

Query this set of features using a supplied FeatureFilter.

Specified by:

filter in interface FeatureHolder

Parameters:

filter - the FeatureFilter to apply.

Returns:

all features in this container which match filter.

filter

public FeatureHolder filter(FeatureFilter fc,
                            boolean recurse)

Return a new FeatureHolder that contains all of the children of this one that passed the filter fc. This method is scheduled for deprecation. Use the 1-arg filter instead.

Specified by:

filter in interface FeatureHolder

Parameters:

fc - the FeatureFilter to apply

recurse - true if all features-of-features should be scanned, and a single flat collection of features returned, or false if just immediate children should be filtered.

getSchema

public FeatureFilter getSchema()

Return a schema-filter for this FeatureHolder. This is a filter which all Features immediately contained by this FeatureHolder will match. It need not directly match their child features, but it can (and should!) provide information about them using FeatureFilter.OnlyChildren filters. In cases where there is no feature hierarchy, this can be indicated by including FeatureFilter.leaf in the schema filter.

For the truly non-informative case, it is possible to return FeatureFilter.all. However, it is almost always possible to provide slightly more information that this. For example, Sequence objects should, at a minimum, return FeatureFilter.top_level. Feature objects should, as a minimum, return FeatureFilter.ByParent(new FeatureFilter.ByFeature(this)).

Specified by:

getSchema in interface FeatureHolder

Returns:

the schema filter

removeFeature

Remove a feature from this FeatureHolder.

Specified by:

removeFeature in interface FeatureHolder

Throws:

ChangeVetoException - if this FeatureHolder does not support feature removal or if the change was vetoed

BioException - if there was an error removing the feature

setStrand

public void setStrand(StrandedFeature.Strand strand)
               throws ChangeVetoException

Set the strand that this feature lies upon.

This will be one of StrandedFeature.POSITIVE or NEGATIVE. NOT IMPLEMENTED.

public StrandedFeature.Strand getStrand()

Retrieve the strand that this feature lies upon.

This will be one of StrandedFeature.POSITIVE or NEGATIVE.

getStrand in interface StrandedFeature

Returns:

one of the Strand constants

hashCode

equals

public boolean equals(Object o)

Features are equal when they have the same parent, type, source and rank.

Overrides:

Form: "(#rank) parent:type,source(location)"

Overrides:

toString in class Object
