Class FlowResult

java.lang.Object

org.dspace.app.xmlui.aspect.administrative.FlowResult

public class FlowResult
extends Object

This class represents the results that may be generated during a flow script in this administrative section. Typically, some method performs an operation and returns an object of type FlowResult, then the flow script can inspect the results object to determine what the next course of action is. Basically, this results object stores all the errors and continuation states that need to be represented. There are four types of information stored: 1) Continuation, this is a simple boolean variable that indicates whether the required operation is complete and the user may continue on to the next step. 2) Notice information, this is a simple encoding of a notice message to be displayed to the user on their next step. There are four parts: outcome, header, message, and characters. See each field for more description on each part. Note: either a message or characters are required. 3) Errors, this is a list of errors that were encountered during processing. Typically, it just consists of a list of errored fields. However occasionally there may be other specialized errors listed. 4) Parameters, this is a map of attached parameters that may be relevant to the result. This should be used for things such as generated id's when objects are newly created.
