DESCRIPTION

       This engine performs a Boolean operation on two inputs, and returns both the result of the
       operation and its inverse.

       The  input fields can have multiple values, allowing the engine to perform several Boolean
       operations in parallel. One input may have more values than the other. In that  case,  the
       last value of the shorter input will be repeated as necessary.

INPUTS

     SoMFBool            a
          First argument to the Boolean operation.

     SoMFBool            b
          Second argument to the Boolean operation.

     SoMFEnum            operation
          The Boolean operation.

OUTPUTS

     (SoMFBool)          output
          Result of the Boolean operation applied to the inputs.

     (SoMFBool)          inverse
          Inverse of output.

METHODS

                         SoBoolOperation()
          Constructor.
