Constructor & Destructor Documentation

TSLMUExtent() [1/2]

TSLMUExtent::TSLMUExtent ( )

inline

TSLMUExtent() [2/2]

TSLMUExtent::TSLMUExtent ( double minX, double minY, double maxX, double maxY, const TSLCoordinateSystem * csys = NULL )

inline

Creates a bounding box with the given extent.

Parameters

minX	The X coordinate of the bottom left corner of the extent.
minY	The Y coordinate of the bottom left corner of the extent.
maxX	The X coordinate of the top right corner of the extent.
maxY	The Y coordinate of the top right corner of the extent.
csys	The coordinate system of this extent.

Member Function Documentation

coordinateSystem() [1/2]

const TSLCoordinateSystem * TSLMUExtent::coordinateSystem ( ) const

inline

Returns

The coordinate system of this extent

coordinateSystem() [2/2]

void TSLMUExtent::coordinateSystem ( const TSLCoordinateSystem * csys )

inline

Sets the coordinate system of this extent

Parameters

csys	The coordinate system for this extent

height()

double TSLMUExtent::height ( ) const

inline

Returns the height of the extent.

intersect()

bool TSLMUExtent::intersect ( const TSLMUExtent & e ) const

inline

Query if Map Unit Extents intersect.

For the purposes of this method, an extent is considered intersecting if it touches the boundary.

Parameters

e	MUExtent to check.

Returns

true if this MUExtent intersects the specified MUExtent, false otherwise.

maxX()

double TSLMUExtent::maxX ( ) const

inline

Returns the top right X coordinate of the extent.

maxY()

double TSLMUExtent::maxY ( ) const

inline

Returns the top right Y coordinate of the extent.

minX()

double TSLMUExtent::minX ( ) const

inline

Returns the bottom left X coordinate of the extent.

minY()

double TSLMUExtent::minY ( ) const

inline

Returns the bottom left Y coordinate of the extent.

operator!=()

bool TSLMUExtent::operator!= ( const TSLMUExtent & e ) const

inline

operator=()

TSLMUExtent & TSLMUExtent::operator= ( const TSLMUExtent & e )

inline

operator==()

bool TSLMUExtent::operator== ( const TSLMUExtent & e ) const

inline

setExtent()

void TSLMUExtent::setExtent ( double minX, double minY, double maxX, double maxY )

inline

Sets the corners of the extent to the given values

Parameters

minX	The X coordinate of the bottom left corner of the new extent.
minY	The Y coordinate of the bottom left corner of the new extent
maxX	The X coordinate of the top right corner of the new extent.
maxY	The Y coordinate of the top right corner of the new extent

width()

double TSLMUExtent::width ( ) const

inline

Returns the width of the extent.
