想要为ATG中的特定属性操纵动态查询对象

Question

我正在使用IntegrationRepositoryView的Integration仓库框架，并覆盖了executeUncachedQuery函数。 每次调用该方法时都要获取一个动态查询。 例如（ean EQUALS 5052931399536）或 （（ean == 5052931399536）和（siteIds包括diyStore）） 我必须为不同的pInput处理方法中的ean值。我们应该如何实现这一目标。

我执行以下操作：

public RepositoryItem[] executeQueryCommand(final Object pInput) throws RepositoryException {
        final String perfName = "executeQueryCommand";
        PerformanceMonitor.startOperation("IntegrationRepositoryView", perfName);
        boolean perfCancelled = false;

        try {
            final IntegrationRepositoryItemDescriptor desc = (IntegrationRepositoryItemDescriptor)getItemDescriptor();

            final IntegrationRepositoryCommandDescriptor queryCommandDesc = desc.getQueryCommand();
            if(queryCommandDesc == null) {
                perfCancelled = true;
                throw new RepositoryException(IntegrationRepositoryConstants.NULL_QUERY_COMMAND);
            }

            final Command queryCommand = queryCommandDesc.getCommand();
            if(queryCommand == null) {
                perfCancelled = true;
                throw new RepositoryException(IntegrationRepositoryConstants.NULL_QUERY_COMMAND);
            }

            final CommandResult result = queryCommand.execute(pInput);

            return processResults(queryCommand, result);
        } catch(final CommandInvocationException cie) {
            perfCancelled = true;
            throw new RepositoryException(cie);
        } 
    }
