Description
This class acts like an union for common data types. A RVariant object holds a single value of a specified type T at a time. You can use GetType to find out what type the variant holds, and get its value by one of the ToT() functions, e.g. ToInt32. Currently, there are two types supported: float and int.
1 x = RLPy.RVariant(-10)
2 print(x.GetType() == RLPy.RVariant.Int32) #true
3
4 f = x.ToFloat()
5 print(f) #-10.0
6
7 y = RLPy.RVariant(10.0)
8 print(y.GetType() == RLPy.RVariant.Float) #true
9
10 n = x.ToInt32()
11 print(n)
Member Functions
GetType ( self )
Get type of this RVariant object.
Returns
- Type of this RVariant object - int
- RLPy.RVariant.Float
- RLPy.RVariant.Int32
- RLPy.RVariantUInt32
1 x = RLPy.RVariant(-10)
2 print(x.GetType() == RLPy.RVariant.Int32) #true
ToFloat ( self, pSucess = None )
Convert to float.
Parameters
- pSucess [IN] success or not - bool
Returns
- Value after conversion - float
1 x = RLPy.RVariant(-10)
2 f = x.ToFloat()
3 print(f)
ToInt32 ( self, pSucess = None )
Convert to int32_t.
Parameters
- pSucess [IN] success or not - bool
Returns
- Signed integer value after conversion - int32
1 f = RLPy.RVariant(-10.0)
2 x = f.ToInt32()
3 print(x)
ToUInt32 ( self, pSucess = None )
Convert to uint32_t.
Parameters
- pSucess [IN] success or not - bool
Returns
- Unsigned integer value after conversion - uint32
1 f = RLPy.RVariant(10.0)
2 x = f.ToUInt32()
3 print(x)
