Examples with ArrayType org.eclipse.ceylon.langtools.tools.javac.code.Type.ArrayType used on opensource projects

Example 1 with ArrayType

use of org.eclipse.ceylon.langtools.tools.javac.code.Type.ArrayType in project ceylon by eclipse.

the class CeylonModelLoader method getFunctionalInterfaceType.

@Override
protected FunctionalInterfaceType getFunctionalInterfaceType(TypeMirror typeMirror) throws ModelResolutionException {
    if (typeMirror.getKind() != TypeKind.DECLARED)
        throw new ModelResolutionException("Failed to find functional interface type in " + typeMirror);
    // FIXME: possibly apply other optimisations to lighten the lookup cost? see what javac does
    Type type = ((JavacType) typeMirror).type;
    try {
        Type descriptorType = types.findDescriptorType(type);
        // Let's be honest I've no idea what this means, but it happens and Javac seems to refuse it too
        if (descriptorType.hasTag(TypeTag.FORALL))
            throw new ModelResolutionException("Failed to find functional interface type in " + typeMirror);
        MethodType methodDescriptorType = (MethodType) descriptorType;
        MethodSymbol methodSymbol = (MethodSymbol) types.findDescriptorSymbol(type.tsym);
        List<Type> parameterTypes = methodDescriptorType.getParameterTypes();
        ListBuffer<TypeMirror> mirrorParameterTypes = new ListBuffer<>();
        for (int i = 0; i < parameterTypes.size(); i++) {
            Type parameterType = parameterTypes.get(i);
            if (methodSymbol.isVarArgs() && i == parameterTypes.size() - 1)
                parameterType = ((ArrayType) parameterType).getComponentType();
            mirrorParameterTypes.add(new JavacType(parameterType));
        }
        return new FunctionalInterfaceType(new JavacMethod(new JavacClass(methodSymbol.enclClass()), methodSymbol), new JavacType(methodDescriptorType.getReturnType()), mirrorParameterTypes.toList(), methodSymbol.isVarArgs());
    } catch (Symbol.CompletionFailure err) {
        // bad luck
        throw new ModelResolutionException("Failed to find functional interface type in " + typeMirror, err);
    } catch (FunctionDescriptorLookupError err) {
        throw new ModelResolutionException("Failed to find functional interface type in " + typeMirror, err);
    }
}

Example 2 with ArrayType

use of org.eclipse.ceylon.langtools.tools.javac.code.Type.ArrayType in project ceylon by eclipse.

the class JavacType method getComponentType.

@Override
public TypeMirror getComponentType() {
    if (!componentTypeSet && type instanceof ArrayType) {
        Type compType = ((ArrayType) type).getComponentType();
        if (compType != null) {
            componentType = new JavacType(compType);
        }
        componentTypeSet = true;
    }
    return componentType;
}
