Logic Op - Branch

Overview

The Branch operation is used to perform a change of control with the operation sequence. By default, operations are executed in sequential order starting from operation index 0.

The branch operation allows looping and branching within the operations sequence.

Direction: INTERNAL
From: N/A
To: N/A

Attributes

The operation attributes are as follows.

Attribute	Type	Description
`type`	String	`eval`
`expression`	String	[Required] The expression to evaluate, typically referencing `$v`, `$i` or `$g`. This attribute is always evaluated as an expression.
`on_true`	String	Optional `label` of operation to jump to if the `expression` evaluates as `true`.
`on_false`	String	Optional `label` of operation to jump to if the `expression` evaluates as `false`.

Note: If the relevant ontrue or onfalse attribute is not configured, control will flow to the following operation.

Note: The ontrue or onfalse label names are static. They are never evaluated as expressions.

Note: The ontrue and onfalse attributes (if configured) must refer to a matching label on one of the operations. This check is performed at the start of the test run. The test run will not commence if the labels cannot be resolved.

Example

This is an example entry within the operations array:

{ 
    "type": "branch", 
    "expression": "$v->{threshold} > 10",
    "on_true": "increment3"
}
