Method Details

getOrdinal

int getOrdinal()

Returns the ordinal (index) of this parameter within the function signature.

isAutoParameter

boolean isAutoParameter()

Returns:

true if this parameter is automatically generated based upon the associated function calling convention and function signature. An example of such a parameter include the "__return_storage_ptr__" parameter.

getAutoParameterType

AutoParameterType getAutoParameterType()

If this is an auto-parameter this method will indicate its type.

Returns:

auto-parameter type of null if not applicable.

isForcedIndirect

boolean isForcedIndirect()

If this parameter which was forced by the associated calling convention to be passed as a pointer instead of its original formal type.

Returns:

true if this parameter was forced to be passed as a pointer instead of its original formal type

getFormalDataType

DataType getFormalDataType()

Get the original formal signature data type before a possible forced indirect was possibly imposed by the functions calling convention. The Variable.getDataType() method will always return the effective data type which corresponds to the allocated variable storage.

Returns:

Formal data type. This type will only differ from the Variable.getDataType() value if this parameter isForcedIndirect.
