SYNOPSIS
if --help |
condition_expression of command_line
DESCRIPTION
Starts if-else control flow.
The if statement includes command_line (which is a CLI command
or an operation) that is executed at the beginning of the if-else
control flow. After the response of the command_line is received
from the controller, it is evaluated using the condition_expression.
condition_expression consists of a node path, equals sign ('==') and
a specific value. If the target value designated with the node path
equals to the specified value, then the condition is met and
the if block (which is a batch) is executed. If the condition
wasn't met then the else block, if present, and which is also a batch,
would be executed.
Simple example of if-else control flow which changes
system property's value named test to the opposite boolean
value every time it is executed:
if result.value==true of /system-property=test:read-resource
/system-property=test:write-attribute(name=value,value=false)
else
/system-property=test:write-attribute(name=value,value=true)
ARGUMENTS
--help - prints this description.
command_line - CLI command or an operation whose response
should be evaluated to determine which
block of the if-else should be executed next;
condition_expression - an expression that evaluates the response
and based on which the next block of the
