| [Solved] Using an extended set of primitive ECore types [message #1831937] |

Hello. Some types in my metamodel contains attributes of types like EByte, EFloat, which is unsupported by OCL spec. In the ATL rules (with EMFTVM compiler) I sometime need to assign a static values to such attributes like
SomeFloatAttribute <- 10.0,
This doesn't work, because at runtime this value treated as Double which produces ClassCastException when assigning to the attribute of type Float.
I did some research but as far found only two ways:
- change metamodel, limit use of types only supported by OCL
- use some sort of calls to a native java helper class to convert types
I hope I miss the clean and convenient way to solve this. Any help is appreciated :)

Primitive types can be obtained by using native Java methods on Integer, Double, and String:
-- @atlcompiler emftvm
module PrimitiveTypeTest;
create OUT : PTT from IN : PTT;
rule Entity {
from
s : PTT!Entity
to
t : PTT!Entity (
byte <- 15.byteValue(),
char <- 't'.charAt(0),
double <- 15.8,
float <- 15.8.floatValue(),
int <- 31,
long <- 31.longValue(),
name <- 'Entity',
short <- 31.shortValue()
)
}
