Detailed Description

A stand-alone parameter with no backing symbol.

Name, data-type, and storage location is stored internally to the object. This is suitable for return values, function pointer prototypes, or functions that haven't been fully analyzed.

Member Function Documentation

virtual Symbol* ParameterBasic::getSymbol ( void  ) const

inlinevirtual

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.

References LowlevelError::LowlevelError().

void ParameterBasic::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.

References Datatype::getSize(), and AddrSpace::type.

void ParameterBasic::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.

References TypeFactory::getBase(), AddrSpace::type, and TYPE_UNKNOWN.
