TypeAsExpression

java.lang.Object
- gw.internal.gosu.parser.ParsedElement
- - gw.internal.gosu.parser.Expression
  - - gw.internal.gosu.parser.expressions.TypeAsExpression

All Implemented Interfaces:

ITypeAsExpression, IExpression, IHasType, IParsedElement

Direct Known Subclasses:

ImplicitTypeAsExpression
```
public class TypeAsExpression
extends Expression
implements ITypeAsExpression
```
Represents a typeas expression in the Gosu grammar:
```
 typeas-expression
   <conditional-or-expression> typeas <type-literal>
 
```
