Description:

addHash
unsigned int LVecBase2d::add_hash(unsigned int hash) const;

Description: Adds the vector into the running hash.

addToCell
void LVecBase2d::add_to_cell(int i, double value);

These next functions add to an existing value. i.e. foo.set_x(foo.get_x() + value) These are useful to reduce overhead in scripting languages:
Description:

addX
void LVecBase2d::add_x(double value);

These next functions add to an existing value. i.e. foo.set_x(foo.get_x() + value) These are useful to reduce overhead in scripting languages:
Description:

addY
void LVecBase2d::add_y(double value);

Description:

almostEqual
bool LVecBase2d::almost_equal(LVecBase2d const &other, double threshold) const;

Description: Returns true if two vectors are memberwise equal within a specified tolerance.
Description: Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.

compareTo
int LVecBase2d::compare_to(LVecBase2d const &other) const;

Description: This flavor of compare_to uses a default threshold value based on the numeric type.
Description: Sorts vectors lexicographically, componentwise. Returns a number less than 0 if this vector sorts before the other one, greater than zero if it sorts after, 0 if they are equivalent (within the indicated tolerance).

dot
double LVecBase2d::dot(LVecBase2d const &other) const;

Description:

fill
void LVecBase2d::fill(double fill_value);

Description: Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

fmax
LVecBase2d LVecBase2d::fmax(LVecBase2d const &other);

Description:

fmin
LVecBase2d LVecBase2d::fmin(LVecBase2d const &other);

Description:

getCell
double LVecBase2d::get_cell(int i) const;

Description:

getClassType
static TypeHandle LVecBase2d::get_class_type(void);

Undocumented function.

getData
double const *LVecBase2d::get_data(void) const;

Description: Returns the address of the first of the two data elements in the vector. The next element occupies the next position consecutively in memory.

getHash
unsigned int LVecBase2d::get_hash(void) const;

Description: Returns a suitable hash for phash_map.

getNumComponents
int LVecBase2d::get_num_components(void) const;

Description: Returns the number of elements in the vector, two.

getX
double LVecBase2d::get_x(void) const;

Description:

getY
double LVecBase2d::get_y(void) const;

Description:

isNan
bool LVecBase2d::is_nan(void) const;

Description: Returns true if any component of the vector is not-a-number, false otherwise.

operator !=
bool LVecBase2d::operator !=(LVecBase2d const &other) const;

Description:

operator *
LVecBase2d LVecBase2d::operator *(double scalar) const;

Description:

operator *=
void LVecBase2d::operator *=(double scalar);

Description:

operator +
LVecBase2d LVecBase2d::operator +(LVecBase2d const &other) const;

Description:

operator +=
void LVecBase2d::operator +=(LVecBase2d const &other);

Description:

operator -
LVecBase2d LVecBase2d::operator -(LVecBase2d const &other) const;

Description:

operator -
LVecBase2d LVecBase2d::operator -(LVecBase2d const &other) const;

Description:

operator -=
void LVecBase2d::operator -=(LVecBase2d const &other);

Description:

operator /
LVecBase2d LVecBase2d::operator /(double scalar) const;

Description:

operator /=
void LVecBase2d::operator /=(double scalar);

Description:

operator <
bool LVecBase2d::operator <(LVecBase2d const &other) const;

Description: This performs a lexicographical comparison. It's of questionable mathematical meaning, but sometimes has a practical purpose for sorting unique vectors, especially in an STL container. Also see compare_to().

operator =
LVecBase2d &LVecBase2d::operator =(LVecBase2d const &copy);

Description:

operator ==
bool LVecBase2d::operator ==(LVecBase2d const &other) const;

Description:

operator []
double LVecBase2d::operator [](int i) const;

Description:

operator delete
void LVecBase2d::operator delete(void *ptr);

Undocumented function.

operator new
void *LVecBase2d::operator new(unsigned int size);

Undocumented function.

output
void LVecBase2d::output(ostream &out) const;

Description:

pythonRepr
void LVecBase2d::python_repr(ostream &out, string const &class_name) const;

Description:

set
void LVecBase2d::set(double x, double y);

Description:

setCell
void LVecBase2d::set_cell(int i, double value);

Description:

setX
void LVecBase2d::set_x(double value);

validatePtr
static bool LVecBase2d::validate_ptr(void const *ptr);

Undocumented function.

zero
static LVecBase2d const &LVecBase2d::zero(void);

Description: Returns a zero-length vector.
