Class FileUploadExecutorManager

java.lang.Object

org.wso2.carbon.ui.transports.fileupload.FileUploadExecutorManager

public class FileUploadExecutorManager
extends Object

This class is responsible for delegating the file upload requests to the different FileUploadExecutors.

The FileUploadExecutors may be registered in the following manner:

1. 1. Using FileUploadConfig configuration section in the carbon.xml
2. 2. Instances of AbstractFileUploadExecutor registered as OSGi services
3. 3. Using component.xml file in UI components

If a FileUploadExecutor cannot be found in the above 3 collections, as a final resort, we will finally try to upload the file using an AnyFileUploadExecutor, if it has been registered in the carbon.xml file. Searching for an FileUploadExecutor in the above 3 types of items is done using the chain of execution pattern. As soon as a FileUploadExecutor which can handle the uploaded file type is found, execution of the chain is terminated.
