Example 2 with INodeFuncObject

use of buildcraft.lib.expression.api.INodeFunc.INodeFuncObject in project BuildCraft by BuildCraft.

the class NodeCasting method castToObject.

public static <T> INodeFuncObject<T> castToObject(INodeFunc func, Class<T> to) throws InvalidExpressionException {
    Class<?> from = NodeTypes.getType(func);
    if (from == to) {
        return (INodeFuncObject<T>) func;
    }
    FunctionContext castingContext = new FunctionContext(NodeTypes.getContext(from), NodeTypes.getContext(to));
    INodeFunc caster = castingContext.getFunction("(" + NodeTypes.getName(to) + ")", Collections.singletonList(from));
    if (caster == null) {
        if (to == String.class) {
            return (INodeFuncObject<T>) castToString(func);
        }
        throw new InvalidExpressionException("Cannot cast from " + NodeTypes.getName(from) + " to " + NodeTypes.getName(to));
    }
    return new INodeFuncObject<T>() {

        @Override
        public INodeObject<T> getNode(INodeStack stack) throws InvalidExpressionException {
            return (INodeObject<T>) caster.getNode(new NodeStack(func.getNode(stack)));
        }

        @Override
        public Class<T> getType() {
            return to;
        }
