saveSetAssociateResults

protected void saveSetAssociateResults(BaseAssociateSets<Desc>.SetStruct set)

After associating a set run association these processes and saves the results

getMatches

public FastAccess<AssociatedIndex> getMatches()

Description copied from interface: Associate

List of associated features. Indexes refer to the index inside the input lists.

Specified by:

getMatches in interface Associate<Desc>

Returns:

List of associated features.

getUnassociatedSource

public DogArray_I32 getUnassociatedSource()

Description copied from interface: Associate

Indexes of features in the source set which are not associated. WARNING: In some implementations the unassociated list is recomputed each time this function is invoked. In other implementations it was found virtually for free while the matches are found.

Specified by:

getUnassociatedSource in interface Associate<Desc>

Returns:

List of unassociated source features by index.

getUnassociatedDestination

public DogArray_I32 getUnassociatedDestination()

Description copied from interface: Associate

Indexes of features in the destination set which are not associated. WARNING: In some implementations the unassociated list is recomputed each time this function is invoked. In other implementations it was found virtually for free while the matches are found.

Specified by:

getUnassociatedDestination in interface Associate<Desc>

Returns:

List of unassociated destination features by index.

setMaxScoreThreshold

public void setMaxScoreThreshold(double score)

Description copied from interface: Associate

Associations are only considered if their score is less than or equal to the specified threshold. To remove any threshold test set this value to Double.MAX_VALUE

Specified by:

setMaxScoreThreshold in interface Associate<Desc>

Parameters:

score - The threshold.

getScoreType

public MatchScoreType getScoreType()

Description copied from interface: Associate

Specifies the type of score which is returned.

Specified by:

getScoreType in interface Associate<Desc>

Returns:

Type of association score.

uniqueSource

public boolean uniqueSource()

Description copied from interface: Associate

If at most one match is returned for each source feature.

Specified by:

uniqueSource in interface Associate<Desc>

Returns:

true for unique source association

uniqueDestination

public boolean uniqueDestination()

Description copied from interface: Associate

If at most one match is returned for each destination feature.

Specified by:

uniqueDestination in interface Associate<Desc>

Returns:

true for unique destination association

getDescriptionType

public Class<Desc> getDescriptionType()

Description copied from interface: Associate

Returns the type of object it can associate

Specified by:
