Decision Record Contact Step

Represents a branch decision flow step. A branch step contains a list of branchCases and a defaultCase. During the execution of a branch step each branchCases condition is evaluated in order. The decision flow will follow the first branchCases condition that evaluates as true. If a branchCases condition does not evaluate as true, then the defaultCase path for the branchStep is followed.

Decision Case

Represents a model be referenced as a step within a decision flow.

Model Decision Step

Represents a condition step within a decision flow.

Represents a term that is being recorded for auditing purposes during contact recording.

Audit Term

Represents a simple condition.  The left hand side (lhs), right hand side (rhs) and operator of the condition are evaluated to produce a boolean result of "true" or "false".  The left hand side may be a variable or an experssion.

Decision Simple Branch Condition

Represents a compound condition.  The left hand side (lhs), right hand side (rhs) and operator of the condition are evaluated to produce a boolean result of "true" or "false".  A compound condition has a left hand side (lhsSimpleCondition or lhsCompoundCondition) a right hand side (rhsSimpleCondition or rhsCompoundCondition) and a boolean operator.
