overridedefault

Member Function Documentation

equals()

bool NES::Undefined::equals ( DataTypePtr  otherDataType )

overridevirtual

Checks if two data types are equal.

Parameters

otherDataType

Returns

Implements NES::DataType.

isUndefined()

bool NES::Undefined::isUndefined ( ) const

inlineoverridevirtual

Checks if this data type is Undefined.

Reimplemented from NES::DataType.

join()

DataTypePtr NES::Undefined::join ( DataTypePtr  otherDataType )

overridevirtual

Calculates the joined data type between this data type and the other. If they have no possible joined data type, the coined type is Undefined.

Parameters

other

data type

Returns

DataTypePtr joined data type

Implements NES::DataType.

Here is the call graph for this function:

toString()

std::string NES::Undefined::toString ( )

overridevirtual

Returns a string representation of the data type.

Returns

string
