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.
x = RLPy.RVariant(-10)
print(x.GetType() == RLPy.RVariant.Int32) #true
f = x.ToFloat()
print(f) #-10.0
y = RLPy.RVariant(10.0)
print(y.GetType() == RLPy.RVariant.Float) #true
n = x.ToInt32()
print(n)
Member Functions
GetType ( self )
Get type of a RVariant object.
Returns
- Type of a RVariant object - int
- RLPy.RVariant.Float
- RLPy.RVariant.Int32
- RLPy.RVariantUInt32
x = RLPy.RVariant(-10)
print(x.GetType() == RLPy.RVariant.Int32) #true
ToFloat ( self, pSucess = None )
Convert to float.
See Also: ToInt32 ( self, pSucess = None ), ToUInt32( self, pSucess = None )
Parameters
- pSucess [IN] success or not - bool
Returns
- Value after conversion - float
x = RLPy.RVariant(-10)
f = x.ToFloat()
print(f)
ToInt32 ( self, pSucess = None )
Convert to int32_t.
See Also: ToFloat ( self, pSucess = None ), ToUInt32( self, pSucess = None )
Parameters
- pSucess [IN] success or not - bool
Returns
- Signed integer value after conversion - int32
f = RLPy.RVariant(-10.0)
x = f.ToInt32()
print(x)
ToUInt32( self, pSucess = None )
Convert to uint32_t.
See Also: ToFloat ( self, pSucess = None ), ToInt32 ( self, pSucess = None )
Parameters
- pSucess [IN] success or not - bool
Returns
- Unsigned integer value after conversion - uint32
f = RLPy.RVariant(10.0)
x = f.ToUInt32()
print(x)
