Member Function Documentation

AllocateValue()

FeatureValue * osmscout::LayerFeature::AllocateValue ( void *  buffer )

overridevirtual

Reimplemented from osmscout::Feature.

GetName()

std::string osmscout::LayerFeature::GetName ( ) const

overridevirtual

Returns the name of the feature.

Implements osmscout::Feature.

References NAME.

GetValueAlignment()

size_t osmscout::LayerFeature::GetValueAlignment ( ) const

overridevirtual

If feature have value object, this method returns alignment requirements of the value type (alignof( type-id )).

Reimplemented from osmscout::Feature.

GetValueSize()

size_t osmscout::LayerFeature::GetValueSize ( ) const

overridevirtual

A feature, if set for an object, can hold a value.

If there is no value object, this method returns 0, else it returns the C++ size of the value object.

Reimplemented from osmscout::Feature.

Initialize()

void osmscout::LayerFeature::Initialize ( TagRegistry &  tagRegistry )

overridevirtual

Does further initialization based on the current TagRegistry.

For example it registers Tags (and stores their TagId) for further processing.

Implements osmscout::Feature.

References osmscout::TagRegistry::RegisterTag().

Parse()

void osmscout::LayerFeature::Parse ( TagErrorReporter &  reporter, const TagRegistry &  tagRegistry, const FeatureInstance &  feature, const ObjectOSMRef &  object, const TagMap &  tags, FeatureValueBuffer &  buffer  ) const

overridevirtual

Implements osmscout::Feature.

References osmscout::FeatureValueBuffer::AllocateValue(), osmscout::FeatureInstance::GetIndex(), osmscout::TagErrorReporter::ReportTag(), osmscout::LayerFeatureValue::SetLayer(), and osmscout::StringToNumber().
