Detailed Description

The SoMFVec2d class is a container for SbVec2d vectors.

This field is used where nodes, engines or other field containers needs to store an array of vectors with two elements.

This field supports application data sharing through a setValuesPointer() method. See SoMField documentation for information on how to use this function.

Member Function Documentation

SoType SoMFVec2d::getClassTypeId (void) [static]

Returns a unique type identifier for this field class.

See also:

getTypeId(), SoType

Reimplemented from SoMField.

SoType SoMFVec2d::getTypeId (void) const [virtual]

Returns the type identification instance which uniquely identifies the Coin field class the object belongs to.

See also:

getClassTypeId(), SoType

Implements SoField.

void SoMFVec2d::copyFrom (const SoField &f) [virtual]

Copy value(s) from f into this field. f must be of the same type as this field.

Implements SoField.

SbBool SoMFVec2d::isSame (const SoField &f) const [virtual]

Check for equal type and value(s).

Implements SoField.

void SoMFVec2d::deleteAllValues (void) [protected], [virtual]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoMField.

void SoMFVec2d::copyValue (intto, intfrom) [protected], [virtual]

This method is used for moving values around internally within a multivalue field. It needs to be overridden in each field so it automatically takes care of running copy contructors where necessary.

Implements SoMField.

const SbVec2d* SoMFVec2d::getValues (const intstart) const [inline]

\ Returns a pointer to the values array. \

void SoMFVec2d::initClass (void) [static]

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.

Reimplemented from SoMField.

void SoMFVec2d::setValues (intstart, intnumarg, const doublexy[][2])

Set num vector array elements from xy, starting at index start.

void SoMFVec2d::set1Value (intidx, doublex, doubley)

Set the vector at idx.

void SoMFVec2d::set1Value (intidx, const doublexy[2])

Set the vector at idx.

void SoMFVec2d::setValue (doublex, doubley)

Set this field to contain a single vector with the given element values.

void SoMFVec2d::setValue (const doublexy[2])

Set this field to contain a single vector with the given element values.
