Member Function Documentation

virtual VectorShapeRef WhirlyGlobe::VectorReader::getNextObject

(

const StringSet *

filter

)

[pure virtual]

Returns one of the vector types. Keep enough state to figure out what the next one is. You can skip any attributes not named in the filter. Or just ignore it.

Implemented in WhirlyGlobe::ShapeReader.

virtual VectorShapeRef WhirlyGlobe::VectorReader::getObjectByIndex	(	unsigned int	vecIndex,
		const StringSet *	filter
	)		[inline, virtual]

Return an object that corresponds to the given index. You need to be able to seek in your file format for this. The filter works the same as for getNextObect()

Reimplemented in WhirlyGlobe::ShapeReader.
