classifyFeature()

virtual bool TSLFeatureClassifierCustom::classifyFeature ( const TSLMUGeometry * geometry, TSLRenderingAttributes & renderingAttribs, TSLSimpleString & childFeatureName ) const

virtual

Query the feature name for a given geometry

Parameters

geometry	The geometry to classify
renderingAttribs	The given TSLRenderingAttributes object will be set to the rendering attributes (if any) of the feature. Not all classifier definitions can specify rendering attributes.
childFeatureName	Returned name of the child feature for this geometry

Returns

'true' if childFeatureName was populated, false if the classification could not be determined.

Implements TSLFeatureClassifier.

clone()

virtual TSLFeatureClassifier * TSLFeatureClassifierCustom::clone ( ) const

virtual

Clone this classifier definition.

Returns

A clone of this object.

Implements TSLFeatureClassifier.

create()

static TSLFeatureClassifierCustom * TSLFeatureClassifierCustom::create ( TSLClientFeatureClassifierCustom * customHandler )

static

Constructor.

getClassifiedFeatures()

virtual bool TSLFeatureClassifierCustom::getClassifiedFeatures ( TSLFeature * rootFeature, unsigned int classificationLevel, bool caseSensitive ) const

virtual

Process the classification definition and add child features to the hierarchy.

Parameters

rootFeature	The top-level feature (TSLFeature) in the hierarchy the sub-classing should be applied to.
classificationLevel	The level of this classification, starting at 0.
caseSensitive	Whether the identification of existing classifications should be case sensitive or not.

Returns

true if any new features were created, false otherwise.

Implements TSLFeatureClassifier.
