Detailed Description

A parameter with a formal backing Symbol.

Input parameters generally have a symbol associated with them. This class holds a reference to the Symbol object and pulls the relevant parameter information off of it.

Member Function Documentation

Symbol * ParameterSymbol::getSymbol ( void  ) const

virtual

Retrieve the formal Symbol associated with this parameter.

If there is no backing symbol an exception is thrown

Returns

the backing Symbol object

Implements ProtoParameter.

void ParameterSymbol::overrideSizeLockType ( Datatype *  ct )

virtual

Change (override) the data-type of a size-locked parameter.

The original parameter must have a type-lock and TYPE_UNKNOWN data-type. The size-lock is preserved and this can be cleared back to its TYPE_UNKNOWN state.

Parameters

ct	is the overriding data-type

Implements ProtoParameter.

void ParameterSymbol::resetSizeLockType ( TypeFactory *  factory )

virtual

Clear this parameter's data-type preserving any size-lock.

The data-type is converted to a TYPE_UNKNOWN of the same size

Parameters

factory

is the TypeFactory that will construct the unknown data-type

Implements ProtoParameter.
