C++ (Cpp) JLocalEnv::GetIntField示例

示例#1

文件： array.cpp 项目： Epictetus/jruby

extern "C" int
rb_ary_size(VALUE ary)
{
    JLocalEnv env;
    int length = (int)(env->GetIntField(valueToObject(env, ary), RubyArray_length_field));
    checkExceptions(env);
    return length;
}

示例#2

文件： string.cpp 项目： brasten/jruby

int
RubyString::length()
{
    // If already synced with java, just return the cached length value
    if (rwdata.rstring != NULL) {
        return rwdata.rstring->len;
    }

    JLocalEnv env;

    jobject byteList = env->GetObjectField(obj, RubyString_value_field);

    return env->GetIntField(byteList, ByteList_length_field);
}

示例#3

文件： symbol.cpp 项目： Epictetus/jruby

extern "C" ID

{
    std::map<StringKey, ID>::iterator it = nonConstSymbolMap.find(StringKey(name, len));
