    • Method Detail

      • checkPermission

        public boolean checkPermission()
                        throws ECException
        Deprecated. This method has been replaced by ECCommand.getResources()
        This method performs fine grain level access control. This is replaced by resource level access control or checkResourcePermission() in this version. Command writers should not implement this method but implement the getResources() method instead. The default implementation returns true.
        Specified by:
        checkPermission in interface ControllerCommand
        Returns:
        This method returns true if this user has permission to perform the operation on the resource and false otherwise.
        Throws:
        ECException

        public TypedProperty getResponseProperties()
        This method gets the response properties associated with this command. This method is called after a controller command has been executed successfully. It return a Hashtable of name value pairs. The controller command should return a view command name for returning response data.

        For example, it could contain the following properties:

        • EC_VIEWTASKNAME (viewTaskName) - The name of a view command/view task. This is a required parameter.
        • EC_DOCPATHNAME (docname) - The name of a JSP to be forwarded.
        • EC_TEXTDOCUMENT (textDocument)- An InputStream for the text document to be returned.
        • EC_RAWDOCUMENT (rawDocument)- An InputStream for the raw document to be returned.
        • EC_REDIRECTURL (redirecturl) - The name of a redirect URL
        It could also contain other information to be passed as request parameters to the view command.

        The response properties are combined with any default parameters defined in the properties column of the URL configuration before passing on to the view command.

        Specified by:
        getResponseProperties in interface ControllerCommand
        Returns:
        This method returns the response properties.

      • getRetriable

        public boolean getRetriable()

        Returns:
        This method returns true if this command is retriable and false otherwise.

      • getViewInputProperties

        public TypedProperty getViewInputProperties()
        This method gets the input properties that will be passed on to the view command. The default implementation is to return all of the request properties to the view command. The command writer can overwrite this method to return all, part or none of the request properties to the view command.
        Specified by:
        getViewInputProperties in interface ControllerCommand
        Returns:
        This method returns the request properties.

      • isGeneric

        public boolean isGeneric()

      • setRetriable

        public final void setRetriable(boolean value)
        This method sets the retriable property for this command. The retriable property is initialized by the command factory based on the properties defined in the command configuration. This command configuration at runtime can come from the following two locations in the given order of sequence:
        • 1) CommandRegistryEntry retriable setting is assigned from the retriable properties in the PROPERTIES column of the CMDREG table, only when that entry exists in the database table, otherwise,
        • 2) if an instance property called <CommandRegistryRetriableProperty defaultValue="0" (or "false") /> is defined in the wc-server.xml file, then the command factory will use this setting as the default retriable configuration.
        Specified by:
        setRetriable in interface ControllerCommand
        Parameters:
        value - This is a boolean value; true if retriable and false otherwise.
