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

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.
