SelectExpression SysML

class SelectExpression

Implementation of SelectExpression defined in the KerML specification.

Specification:

A SelectExpression is an OperatorExpression whose operator is "select", which resolves to the Function ControlFunctions::select from the Kernel Functions Library.

For language description, see section 7.4.9.3 of the KerML specification. For more details on the model, see section 8.3.4.8.18 of the KerML specification.
