application/vnd.sas.decision.code.file.with.code media type (version 1).

This variant of code file is useful for creating a code file revision without
managing the creation of the underlying file resources used to store the code.

Represents a step containing a custom implemented step within the decision flow. Treatment groups, code files, and other decisions can be referenced using a custom object step.

Custom Object Decision Step

Decision

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 Branch Step

Represents a single case within a branch step of a decision flow. A case can contain a simpleCondition or compoundCondition, but not both.

Decision Case

A paginated list of decision representations, with optional links to first, prev, next, and last page of the collection.

Decision Collection

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.

Decision Compound Branch Condition

Decision Condition Step

Represents a condition step within a decision flow.

Represents a term that is used for a condition comparison within a decision.

Decision Node Type Content

A paginated list of decision node type representations, with optional links to first, prev, next, and last page of the collection.

Decision Node Types Collection

Decision Record Contact Step

Decision Rule Set Step

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

Contains the structure of code that is needed to generate the decision code.

Decision Step Code

Terms that are a part of the signature for the object that is used in a decision step.

Decision Step Code Signature Term

Decision Step Code Signature Term DataGrid Extension

Represents the mapping between the terms input and output by a decision step and the signature entries of the decision.

Decision Step Mapping

A decision type modifies the available functionality that can be used to build a decision. 
Currently it controls the available decision node types that can be used to build a decision.
