Detailed Description

Common interface for data structures that support a random access to stored Pharm.Feature instances.

Implementations have to guarantee that a given Pharm.Feature object is stored only once and its index is unique amongst all contained Pharm.Feature instances. Otherwise algorithms that rely on this behaviour may not work correctly!

Member Function Documentation

◆ getFeature()

Feature CDPL.Pharm.FeatureContainer.getFeature ( int  idx)

Returns a reference to the feature at index idx.

Parameters
idxThe zero-based index of the feature to return.
Returns
A reference to the feature at the specified index.
Exceptions
Base.IndexErrorif idx is not in the range [0, getNumFeatures()).

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ containsFeature()

bool CDPL.Pharm.FeatureContainer.containsFeature ( Feature  feature)

Tells whether the specified feature is part of the feature set.

Parameters
featureThe feature to look for.
Returns
True if feature is part of the set, and False otherwise.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ getFeatureIndex()

int CDPL.Pharm.FeatureContainer.getFeatureIndex ( Feature  feature)

Returns the index of the specified feature.

Parameters
featureThe feature for which to return the index.
Returns
The zero-based index of the specified feature.
Exceptions
Base.ItemNotFoundif the specified feature could not be found.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ getNumFeatures()

int CDPL.Pharm.FeatureContainer.getNumFeatures ( )

Returns the number of features.

Returns
The number of features.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ orderFeatures()

None CDPL.Pharm.FeatureContainer.orderFeatures ( BoolFeature2Functor  func)

Orders the features according to criteria implemented by the provided feature comparison function.

Parameters
funcThe feature comparison function implementing the applied ordering criteria.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ getEntity()

Chem.Entity3D CDPL.Pharm.FeatureContainer.getEntity ( int  idx)

Returns a reference to the entity at index idx.

Forwards to getFeature() and exists to satisfy the Chem.Entity3DContainer interface.

Parameters
idxThe zero-based entity index.
Returns
A reference to the entity at the specified index.
Exceptions
Base.IndexErrorif idx is not in the range [0, getNumFeatures()).

Reimplemented from CDPL.Chem.Entity3DContainer.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ getNumEntities()

int CDPL.Pharm.FeatureContainer.getNumEntities ( )

Returns the number of entities.

Forwards to getNumFeatures() and exists to satisfy the Chem.Entity3DContainer interface.

Returns
The number of contained features.

Reimplemented from CDPL.Chem.Entity3DContainer.

Reimplemented in CDPL.Pharm.Pharmacophore.

◆ __contains__() [1/2]

bool CDPL.Pharm.FeatureContainer.__contains__ ( Base.LookupKey  key)

Returns the result of the membership test operation key in self.

Parameters
keyThe value to test for membership.
Returns
The result of the membership test operation.

Reimplemented in CDPL.Pharm.Pharmacophore, and CDPL.Pharm.FeatureSet.

◆ __contains__() [2/2]

bool CDPL.Pharm.FeatureContainer.__contains__ ( Feature  feature)

Returns the result of the membership test operation feature in self.

Parameters
featureThe value to test for membership.
Returns
The result of the membership test operation.

Reimplemented in CDPL.Pharm.Pharmacophore, and CDPL.Pharm.FeatureSet.
