Member Function Documentation

addExt()

void OdGeExtents2d::addExt ( const OdGeExtents2d &  extents )

inline

Updates the extents of this Extents object with the specified Extents object.

Parameters

extents

[in] Any 2D Extents object.

Definition at line 128 of file GeExtents2d.h.

addPoint()

void OdGeExtents2d::addPoint ( const OdGePoint2d &  point )

inline

Updates the extents of this Extents object with the specified point.

Parameters

point

[in] Any 2D point.

Definition at line 107 of file GeExtents2d.h.

center()

OdGePoint2d OdGeExtents2d::center ( ) const

inline

Definition at line 251 of file GeExtents2d.h.

comparingSet()

void OdGeExtents2d::comparingSet ( const OdGePoint2d &  pt1, const OdGePoint2d &  pt2  )

inline

Sets the minimum and maximum points for this Extents object to that of the box defined by pt1 and pt2.

Parameters

pt1	[in] First point.
pt2	[in] Second point.

Remarks

pt1 and pt2 need only define a box. They need not be the minimum and maximum points of the box.

Definition at line 274 of file GeExtents2d.h.

contains() [1/2]

bool OdGeExtents2d::contains ( const OdGeExtents2d &  extents ) const

inline

Definition at line 199 of file GeExtents2d.h.

contains() [2/2]

bool OdGeExtents2d::contains ( const OdGePoint2d &  point ) const

inline

Returns true if and only if this Extents object contains the specified object.

Parameters

point	[in] Any 2D point.
extents	[in] Any 2D Extents object.

Definition at line 192 of file GeExtents2d.h.

expandBy()

void OdGeExtents2d::expandBy ( const OdGeVector2d &  vect )

inline

Updates the extents of this Extents object by the specified vector.

Parameters

vect	[in] Any 2D vector.

Definition at line 154 of file GeExtents2d.h.

intersectWith()

IntersectionStatus OdGeExtents2d::intersectWith	(	const OdGeExtents2d &	extents,
		OdGeExtents2d *	pResult = 0
	)		const

Determines the intersection of the specified Extents object with this one, and returns the resulting intersection box.

Parameters

extents	[in] Any 2D Extents object.
pResult	[out] Receives extents of the intersection.

Remarks

pResult object should be created by the caller. Possible return values are as follows.

@untitled table kIntersectUnknown Either or both Extents objects are invalid kIntersectNot The Extents objects are NOT intersecting kIntersectOpIn The specified Extents object is completely within this one kIntersectOpOut This Extents object is completely within the specified one kIntersectOk The Extents objectes are intersecting, and a result is returned

isDisjoint()

bool OdGeExtents2d::isDisjoint ( const OdGeExtents2d &  extents ) const

inline

Returns true if and only if specified Extents object does not intersect this one.

Parameters

extents

[in] Any 2D Extents object.

Definition at line 213 of file GeExtents2d.h.

isEqualTo()

bool OdGeExtents2d::isEqualTo ( const OdGeExtents2d &  extents, const OdGeTol &  tol = OdGeContext::gTol  ) const

inline

Definition at line 298 of file GeExtents2d.h.

isValidExtents()

bool OdGeExtents2d::isValidExtents ( ) const

inline

Returns true if and only if this Extents object contains valid extents.

Remarks

Extents are valid if and only if each member of the minimum extents is less than or equal to the corresponding member of maximum extents.

Definition at line 145 of file GeExtents2d.h.

maxPoint()

const OdGePoint2d& OdGeExtents2d::maxPoint ( ) const

inline

Returns the maximum point of this Extents object.

Definition at line 73 of file GeExtents2d.h.

minPoint()

const OdGePoint2d& OdGeExtents2d::minPoint ( ) const

inline

Returns the minimum point of this Extents object.

Definition at line 67 of file GeExtents2d.h.

inline

Definition at line 262 of file GeExtents2d.h.

operator==()

bool OdGeExtents2d::operator== ( const OdGeExtents2d &  extents ) const

inline

Definition at line 258 of file GeExtents2d.h.

set()

void OdGeExtents2d::set ( const OdGePoint2d &  min, const OdGePoint2d &  max  )
