Logic Op - Branch
Logic Operation - Branch
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 $g
.
This attribute is always evaluated as an expression.
on_true
String
Optional
label
of operation to jump to if the expression
evaluates as true
.
on_false
String
Optional
label
of operation to jump to if the expression
evaluates as false
.
Note: If the relevant on_true
or on_false
attribute is not configured, control will flow to the
following operation.
Note: The on_true
or on_false
label names are static. They are never evaluated as expressions.
Note: The on_true
and on_false
attributes (if configured) must refer to a matching label on
one of the operations. This check is performed at the start of the test run. The test run will
not commence if the labels cannot be resolved.
Example
This is an example entry within the operations
array:
{
"type": "branch",
"expression": "$v->{threshold} > 10",
"on_true": "increment3"
}
