Constructor & Destructor Documentation

BLinearGeo

(

)

[inline, protected]

Default constructor.

This constructor is hidden because this is an abstract class.

BLinearGeo

(

EGeometryType

type

)

[inline, protected]

Constructs a BLinearGeo with the specified geometry type.

This constructor is hidden because this is an abstract base class.

Parameters:

type

The type of BLinearGeo to create.

BLinearGeo

(

const BLinearGeo &

lgeo

)

[inline, protected]

Copy constructor.

This constructor is hidden because this is an abstract class.

Parameters:

lgeo

The BLinearGeo object to copy.

Member Function Documentation

virtual size_t ComputeSize

(

void

)

const [inline, virtual]

Computes the size of the BByteArray required to store this object.

Returns:

The size of the BByteArray.

Reimplemented from BGeometry.

Reimplemented in BAggregateLinear, BArc, BLine, BPath, BPolyline, and BSegment.

virtual void ComputeStats

(

void

)

const [protected, pure virtual]

Calculates the length and MBR of this BLinearGeo.

Implemented in BAggregateLinear, BArc, BLine, BPath, and BPolyline.

virtual bool Contains

(

const BPoint &

point

)

const [inline, virtual]

Determines whether or not the specified BPoint is contained within this BLinearGeo.

Parameters:

point

The point to test for containment.

Returns:

True if the point is contained within this BLinearGeo and false otherwise.

virtual void FromByteArray	(	const BByteArray &	bytes,
		size_t &	startPos
	)			[virtual]

Initializes an instance of this object from a BByteArray.

Parameters:

	bytes	The BByteArray containing the byte representation of the object.
	startPos	The position in the BByteArray where the byte representation begins. This value will be updated to point to the byte past the end of this object in the byte array.

Reimplemented from BGeometry.

Reimplemented in BAggregateLinear, BArc, BLine, BPath, BPolyline, and BSegment.

virtual double GetLength

(

void

)

const [virtual]

Gets the length of this BLinearGeo.

Returns:

The length of this BLinearGeo. The units used to express this length are the same as the units used to express the location of this BLinearGeo.

virtual BByteArray ToByteArray

(

void

)

const [virtual]

Stores this object in a BByteArray.

Returns:

A BByteArray that stores the contents of this object.

Reimplemented from BGeometry.

Reimplemented in BAggregateLinear, BArc, BLine, BPath, BPolyline, and BSegment.
