How to retrieve metadata attributes Java Core API v2

Billy S.

Hi,

Porting my Android app from Core API v1 to v2, I wonder how to get to metadata attributes such as modified time (server_modified / client_modified), version number, etc. from Java Core API v2.  I am using syntax such as below to retrieve delta.  The question is how to get the above attributes from metadata, which should be available according to v2 documentation.  Could you provide an example how to make such calls?  Thanks in advance.

ListFolderResult result = client.files().listFolder("");
for (Metadata metadata : result.getEntries()) {
...
}

Hi Billy, a Metadata object like in your sample can be for either a file, folder, or deleted object, so you need cast it to the respective type, FileMetadata, FolderMetadata, DeletedMetadata, to access the properties specific to each. 

For example, you can do something like this:

System.out.println(metadata.getPathLower());
if (metadata instanceof FileMetadata) {
    System.out.println(((FileMetadata) metadata).getServerModified());
    System.out.println(((FileMetadata) metadata).getClientModified());
    System.out.println(((FileMetadata) metadata).getRev());
}
