    Session: How to Check if an Attachment Exists

    • To check whether a document contains a certain attachment, use the method exists() from the session.advanced().attachments() operations.

    • This does not load the document or the attachment from the server, and it does not cause the session to track the document.

    • In this page:

    Syntax 

    boolean exists(String documentId, String name);
    Parameter Type Description
    documentId String The ID of the document you want to check for the attachment
    name String The name of the attachment you want to check the document for
    Return Value Description
    boolean Indicates if a document with the specified ID exists in the database

    Example 

    boolean exists = session
                    .advanced()
                    .attachments()
                    .exists("categories/1-A","image.jpg");

if (exists) {
    // do something
}
