Constructor & Destructor Documentation

SbVec2b::SbVec2b ( void  ) [inline]

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().

SbVec2b::SbVec2b ( const int8_t  v[2]) [inline]

Constructs an SbVec2b instance with initial values from v.

SbVec2b::SbVec2b ( int8_t  x,
int8_t  y 
) [inline]

Constructs an SbVec2b instance with the initial vector endpoint set to <x,y>.

SbVec2b::SbVec2b ( const SbVec2ub v) [inline, explicit]

Constructs an SbVec2b instance with initial values from the unsigned 8-bit vector v.

SbVec2b::SbVec2b ( const SbVec2s v) [inline, explicit]

Constructs an SbVec2b instance with initial values from the short integer precision vector v.

SbVec2b::SbVec2b ( const SbVec2i32 v) [inline, explicit]

Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.

See also:
getValue()
SbVec2b & SbVec2b::setValue ( int8_t  x,
int8_t  y 
) [inline]

Set new coordinates for the vector. Returns reference to self.

See also:
getValue()
SbVec2b & SbVec2b::setValue ( const SbVec2ub v)

Sets this vector to the unsigned 8-bit integer precision vector v, converting the vector to an 8-bit integer precision vector

SbVec2b & SbVec2b::setValue ( const SbVec2s v)

Sets this vector to the short integer precision vector v, converting the vector to an 8-bit integer precision vector.

SbVec2b & SbVec2b::setValue ( const SbVec2i32 v)

Sets this vector to the 32-bit integer precision vector v, converting the vector to an 8-bit integer precision vector.

const int8_t * SbVec2b::getValue ( void  ) const [inline]

Returns a pointer to an array of two 8-bit integers containing the x and y coordinates of the vector.

See also:
setValue()
void SbVec2b::getValue ( int8_t &  x,
int8_t &  y 
) const [inline]

Returns the x and y coordinates of the vector.

See also:
setValue()
