C++ CCopasiObject::getObjectParent方法代码示例

/**
 * This method is used for the export of several layout elements.
 * Layout elements can reference model elements, but when a referenced model element
 * is deleted, the layout is not infomred about this yet, so we end up with dnagling
 * references.
 * In order to not write these dangling references to file, we check if the reference
 * belongs to a valid object in the same datamodel. If not, we issue a warning.
 * This warning is only issued once during a save process.
 *
 * If the key belongs to an object in the same datamodel, true is returned, else false is returned.
