When the defined flow processor is executed at runtime, each state in the flow is represented as a Java object. When the flow enters a state, the Java object that represents the state is initiated and activated by a processor. After creating a palette object and the mapping file of the palette object, technical developers miust implement a Java class corresponding to this object. The class should extend DSEState or its derive classes such as DSEHtmlState.

To implement the logic of a state, technical developers must override the following two methods:

The public Object initializeFrom(Tag aTag) throws java.io.IOException, com.ibm.btt.base.DSEException method is invoked when a processor initializes the state from a tag. Because the state might may have several properties, technical developers must initiate these properties from a tag when the state is initiated.

Below is a sample of the implementation of the public Object initializeFrom(Tag aTag) throws java.io.IOException, com.ibm.btt.base.DSEException method.

The public void activate() throws DSEInvalidArgumentException, DSEProcessorException method is invoked when a processor active the state. Technical developers must to override this method to implement state specific logic.
