@Override
public boolean enterThrowNode(final ThrowNode throwNode) {
    lineNumber(throwNode);

    if (throwNode.isSyntheticRethrow()) {
        //do not wrap whatever this is in an ecma exception, just rethrow it
        load(throwNode.getExpression());
        method.athrow();
        return false;
    }

    method._new(ECMAException.class).dup();

    final Source source     = lc.getCurrentFunction().getSource();

    final Expression expression = throwNode.getExpression();
    final int        position   = throwNode.position();
    final int        line       = throwNode.getLineNumber();
    final int        column     = source.getColumn(position);

    load(expression, Type.OBJECT);

    method.load(source.getName());

示例2: enterThrowNode

import jdk.nashorn.internal.ir.ThrowNode; //导入方法依赖的package包/类
@Override
public boolean enterThrowNode(final ThrowNode throwNode) {
    if(!method.isReachable()) {
        return false;
    }
    enterStatement(throwNode);

    if (throwNode.isSyntheticRethrow()) {
        method.beforeJoinPoint(throwNode);

        //do not wrap whatever this is in an ecma exception, just rethrow it
        final IdentNode exceptionExpr = (IdentNode)throwNode.getExpression();
        final Symbol exceptionSymbol = exceptionExpr.getSymbol();
        method.load(exceptionSymbol, EXCEPTION_TYPE);
        method.checkcast(EXCEPTION_TYPE.getTypeClass());
        method.athrow();
        return false;
    }

    final Source     source     = getCurrentSource();
    final Expression expression = throwNode.getExpression();
    final int        position   = throwNode.position();
    final int        line       = throwNode.getLineNumber();
    final int        column     = source.getColumn(position);

    // NOTE: we first evaluate the expression, and only after it was evaluated do we create the new ECMAException
    // object and then somewhat cumbersomely move it beneath the evaluated expression on the stack. The reason for
    // this is that if expression is optimistic (or contains an optimistic subexpression), we'd potentially access
    // the not-yet-<init>ialized object on the stack from the UnwarrantedOptimismException handler, and bytecode
    // verifier forbids that.
    loadExpressionAsObject(expression);

    method.load(source.getName());
    method.load(line);
    method.load(column);
    method.invoke(ECMAException.CREATE);

    method.beforeJoinPoint(throwNode);
    method.athrow();

    return false;
}
