Detailed Description

The SoSelectOne class is used to select one value from a set of values.

The output field will be the index'th value of the input multivalue field.

Note that this engine's output field deviates a little from the "standard" output mechanism of the majority of engine classes: the SoSelectOne::output is not a permanent SoEngineOutput instance, but a pointer to a SoEngineOutput instance. The reason for this is that it is necessary to allocate the output field dynamically to make it match what the SoSelectOne::input is connected to since the type of the SoSelectOne::output always should be the same as the type of the SoSelectOne::input.

Constructor & Destructor Documentation

SoSelectOne::SoSelectOne (  SoType    inputtype )

Constructor. Sets the type of the input field. The input field must be of type SoMField.

Member Function Documentation

void SoSelectOne::initClass (  void    )  [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoEngine.

Member Data Documentation

SoSFInt32 SoSelectOne::index

Index of the value from the input field which will be put on the output.

SoMField * SoSelectOne::input

The multivalue input field which we will select a single value from for our output.

SoEngineOutput * SoSelectOne::output

(SoSField) This is the singlevalue field output containing the index'th value of SoSelectOne::input. The type of the field will of course match the type of the input field, i.e. if SoSelectOne::input is an SoMFFloat, SoSelectOne::output will be an SoSFFloat etc.
