Member Function Documentation

clear()

virtual void OdSiSpatialIndex::clear ( )

pure virtual

Clears this SpatialIndex object.

createObject()

static OdSiSpatialIndexPtr OdSiSpatialIndex::createObject ( OdUInt32  flags, unsigned int  initialNumEntity, unsigned int  maxDepth = 30, unsigned int  maxCount = 20, double  eps = 1e-10  )

static

Creates a SpatialIndex object with the specified parameters.

Parameters

flags	[in] Specifies set of flags for Spatial Index creation.
maxDepth	[in] Maximum depth of the Spatial Index.
maxCount	[in] Maximum number of nodes in the SpatialIndex.
eps	[in] Relative tolerance (equalVector).

Returns

pure virtual

Sets the maximum depth of this SpatialIndex object.

Parameters

maxDepth

[in] Maximum depth.

Remarks

maxDepth specifies the maximum number of times the tree-structured SpatialIndex can branch.

setTolerance()

virtual void OdSiSpatialIndex::setTolerance ( const OdGeTol &  tol )

pure virtual

tolerance()

virtual const OdGeTol& OdSiSpatialIndex::tolerance ( ) const

pure virtual

Returns the tolerance of this SpatialIndex object.

Returns
