Method Detail

getNRLDataType

public NRLDataType getNRLDataType()
Description copied from interface: IConstraint
Return a type constant from the NRLDataType class, indicating the data type of the constraint.

This can only be called once a type inference algorithm has been applied to the constraint or the entire AST. Constraints either have type themselves, in the case of primitive constraints, or derived types inherited from expressions. Before type inference is called, the type is always NRLDataType.Type#Unknown.

Specified by:
getNRLDataType in interface IConstraint
Returns:
the type, never null

setNRLDataType

public void setNRLDataType(NRLDataType type)
Description copied from interface: IConstraint
Assign an NRL type to this constraint.

Specified by:
setNRLDataType in interface IConstraint
Parameters:
type - the type
