public class SoSelectOne extends SoEngine
Selects one value from a multiple-value field. This engine selects a single value from a multiple-value field, based on the input field index. The type of the input field can be any subclass of SoMField, and the type of the output is the corresponding subclass of SoSField. For example, if the input type is SoMFVec3f, the output type will be SoSFVec3f. The type is specified when an instance of the class is created. For example, SoSelectOne( SoMFFloat.getClass()) creates an engine that selects one floating-point value.

Note that by default input does not contain any values, and no value is output from the engine.

File format/default:

SelectOne {

    type <inputType>
    input []
    index 0
}
