### Example Usage
|
||||
|
||||
This API extends MST and MstExpression, so you may optimize as both of them:
|
||||
|
||||
```kotlin
|
||||
DoubleField.mstInField { symbol("x") + 2 }.compile()
|
||||
DoubleField.expression("x+2".parseMath())
|
||||
```
|
||||
|
||||
#### Known issues
|
||||
|
||||
- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
|
||||
class loading overhead.
|
||||
- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid class

loading overhead.
|
||||
- This API is not supported by non-dynamic JVM implementations (like TeaVM and GraalVM) because of using class loaders.

### Example Usage
|
||||
|
||||
This API extends MST and MstExpression, so you may optimize as both of them:
|
||||
|
||||
```kotlin
|
||||
DoubleField.mstInField { symbol("x") + 2 }.compile()
|
||||
DoubleField.expression("x+2".parseMath())
|
||||
```
|
||||
|
||||
#### Known issues
|
||||
|
||||
- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
|
||||
class loading overhead.

- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid class

|

- This API is not supported by non-dynamic JVM implementations (like TeaVM and GraalVM) because of using class loaders.
