public : static XxxBasicType PointTypeId

Point Type ID

class PlanInfo: public XxxFuncPlanInfo

Plan structure for function over Point

XxxPointADT(XxxBasicType Id)

Constructor for XxxPointADT

virtual ~XxxPointADT()

Destructor for XxxPointADT

virtual XxxErrCode WriteText(ostream& OutStream, const XxxADTValue* Object, const XxxADTMetaInfo* MetaInfo)

Display function for the txtclient protocol.

Returns:

The status code.

Parameters:

OutStream - Output stream to write to.
Object - Buffer containing the PointStruct.
MetaInfo - Meta info for points.

virtual XxxErrCode ReadText(istream& InStream, XxxADTValue* ObjectRef, const XxxADTMetaInfo* MetaInfo)

Input function for loading points into tables.

Returns:

The status code.

Parameters:

is - Input stream from which to read the PointStruct.
ObjectRef - Buffer in which to store the PointStruct.
MetaInfo - Meta info for points.

virtual XxxBool Equals(const XxxADTValue* Obj1, const XxxADTMetaInfo*, const XxxADTValue* Obj2, const XxxADTMetaInfo*)

Equals method between points.

virtual XxxBool GetBoundingBox(const XxxADTValue*& Object, XxxBoundingBox& Box)

Retrieves the bounding box of this spatial data type. Used by the indexing methods.

virtual XxxErrCode GetCompOp(const char* FName, XxxCompareOp& CompOp, XxxBool& Success)

Retrieves the compare method given a function name and a array of arguments for that function. This is used in index scans and is index independent.
