Class BlockState

java.lang.Object
  org.apache.commons.workflow.BlockState

public class BlockState
extends Object

BlockState represents the current dynamic execution state of a Block that is executing nested Steps. This class will serve for most Block implementations, but may be subclassed for Blocks with a requirement to maintain additional state information (such as a "for" loop that needs to keep track of the starting and ending indexes, and the iteration counter).
