Field expressions have three attributes. These are: operator: This is the operator to apply on the expression. field: The workflow field to test agains Context: The context to search in, which can be one history, current steps, or a workflow instance. author:    Christine Zimmermann Field Summary final public static  int ACTION      Constant for the workflow action field. final public static  int CALLER      Constant for the workflow caller field. final public static  int CURRENT_STEPS      Constant for the history steps context. final public static  int DUE_DATE      Constant for the workflow due date field. final public static  int ENTRY      Constant for the workflow entry context. final public static  int EQUALS      Constant for the equality operator. final public static  int FINISH_DATE      Constant for the workflow finish date field. final public static  int GT      Constant for the greater than operator. final public static  int HISTORY_STEPS      Constant for the history steps context. final public static  int LT      Constant for the less than operator. final public static  int NAME      Constant for the workflow name field. final public static  int NOT_EQUALS      Constant for the not equals operator. final public static  int OWNER      Constant for the workflow owner field. final public static  int START_DATE      Constant for the workflow start date field. final public static  int STATE      Constant for the state field. final public static  int STATUS      Constant for the workflow status field. final public static  int STEP      Constant for the workflow step field.

CALLER final public static int CALLER(Code) Constant for the workflow caller field. CURRENT_STEPS final public static int CURRENT_STEPS(Code) Constant for the history steps context. Specifying this context means that the search should be performed against the workflow current steps. DUE_DATE final public static int DUE_DATE(Code) Constant for the workflow due date field. ENTRY final public static int ENTRY(Code) Constant for the workflow entry context. Specifying this context means that the search should be performed against the workflow entries. EQUALS final public static int EQUALS(Code) Constant for the equality operator. FINISH_DATE final public static int FINISH_DATE(Code) Constant for the workflow finish date field. GT final public static int GT(Code) Constant for the greater than operator. HISTORY_STEPS final public static int HISTORY_STEPS(Code) Constant for the history steps context. Specifying this context means that the search should be performed against the workflow steps. LT final public static int LT(Code) Constant for the less than operator. NAME final public static int NAME(Code) Constant for the workflow name field. NOT_EQUALS final public static int NOT_EQUALS(Code) Constant for the not equals operator. OWNER final public static int OWNER(Code) Constant for the workflow owner field. START_DATE final public static int START_DATE(Code) Constant for the workflow start date field. STATE final public static int STATE(Code) Constant for the state field. STATUS final public static int STATUS(Code) Constant for the workflow status field. STEP final public static int STEP(Code) Constant for the workflow step field.
