These properties are used to configure cLoop running in the Standard Job framework.

The Standard cLoop component belongs to the Orchestration family.

Basic settings

Loop Type

Select a type of loop to be carried out: Expression, Header, or Value.

Expression: Use an expression to determine the loop count.

Header: Use a header to determine the loop count.

Value: Use an argument to set the loop count.

 

When using Expression: In the Language field, select the language of the expression you want to use to determine the loop count between Constant, EL, Groovy, Header, Javascript, JoSQL, JXPath, MVEL, None, OGNL, PHP, Property, Python, Ruby, Simple, SpEL, SQL, XPath, XQuery. Type in the expression in the Expression field.

The Add Namespaces option appears when XPath is selected in the Language list. Select this check box to add namespaces for the Xpath expression. Click [+] to add as many namespaces as required to the table and define the prefix and URI in the corresponding columns.

 

When using Header: Enter the name of the header that you want to use to determine the loop count in header field.

When using Value: Enter an integer you want to set as the loop count in the value field.

Copy

Select this check box to use the copy mode. It is cleared by default.

If this option is disabled, the same exchange will be used for each iteration. So the result from the previous iteration will be visible for the next.

If this option is enabled, each iteration restarts with a fresh copy of the input exchange.
