Class FeatureFilter.ByDescendant

java.lang.Object

org.biojava.bio.seq.FeatureFilter.ByDescendant

All Implemented Interfaces:

Serializable, FeatureFilter, OptimizableFilter

Enclosing interface:

FeatureFilter

public static class FeatureFilter.ByDescendant
extends Object
implements OptimizableFilter

Filter by applying a nested FeatureFilter to all descendant features. Returns true if at least one of them matches the filter. Always false if the feature has no children.

1.2

Methods

Modifier and Type	Method and Description
boolean	accept(Feature f) This method determines whether a feature is to be accepted.
boolean	equals(Object o)
FeatureFilter	getFilter()
int	hashCode()
boolean	isDisjoint(FeatureFilter ff) Returns true if this filter is disjoint from filt - that is, there is no Feature that is accepted by both filters.
boolean	isProperSubset(FeatureFilter ff) Returns true if this filter is a proper subset of sup - that is, for every feature that matches this, it also matches sup.

Constructor Detail

FeatureFilter.ByDescendant

public FeatureFilter.ByDescendant(FeatureFilter ff)

Method Detail

getFilter

public FeatureFilter getFilter()

accept

public boolean accept(Feature f)

Description copied from interface: FeatureFilter

This method determines whether a feature is to be accepted.

Specified by:

accept in interface FeatureFilter

Parameters:

f - the Feature to evaluate

Returns:

true if this feature is to be selected in, or false if it is to be ignored

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

isProperSubset

public boolean isProperSubset(FeatureFilter ff)

Description copied from interface: OptimizableFilter

Returns true if this filter is a proper subset of sup - that is, for every feature that matches this, it also matches sup. The empty filter is a proper subset of all filters. All filters are a proper subset of the all filter. All filters are proper subsets of themselves.

Specified by:

isProperSubset in interface OptimizableFilter

Parameters:

ff - the potential super set

Returns:

true if sup contains all features contained by this filter

isDisjoint

public boolean isDisjoint(FeatureFilter ff)

Description copied from interface: OptimizableFilter

Returns true if this filter is disjoint from filt - that is, there is no Feature that is accepted by both filters. The empty filter is disjoint from all other filters. The all filter is disjoint from none.

Specified by:

isDisjoint in interface OptimizableFilter
