ClearFeatureValues()

void osmscout::FeatureValueBuffer::ClearFeatureValues

(

)

Clears all feature buffer values.

References FreeValue(), and GetFeatureCount().

CopyMissingValues()

void osmscout::FeatureValueBuffer::CopyMissingValues

(

const FeatureValueBuffer &

other

)

Maintains the current values and types and copies over all not already set feature values of the passed instance to the current instance.

Both FeatureValueBuffers do not have to have the same type. Copying is a based on best effort. The copy opperation is expensive.

Parameters

other

instance to copy missing values from.

Untested!
