<webm:switch>
Use the <webm:switch> tag to execute one of multiple blocks of code, based on the value of a variable in the Integration Server pipeline.
Use <webm:case> to define each value and the associated block of code to execute. Integration Server evaluates <webm:case> tags in the order they appear in the JSP. When a case is true, Integration Server executes the associated block of code, then exits the <webm:switch> structure.
To define a default case to be executed if the specified variable does not exist or if none of the other cases is true, specify a <webm:case> tag with no switch_value. The default case must be the last <webm:case> tag in the <webm:switch> tag.
Syntax
<webm:switch variable="variable">
<webm:case value="switch_value1">block_of_code</webm:case>
[<webm:case value="switch_value2">block_of_code</webm:case>...
<webm:case value="switch_valuen">block_of_code</webm:case>]
[<webm:case>block_of_code</webm:case>]
</webm:switch>
Arguments
Argument | Description |
variable | Pipeline variable which value to evaluate. |
switch_value | A value of variable that triggers Integration Server to execute the associated block of code. switch_value must match the value of variable exactly. switch_value is case sensitive. For example, FedEx does not match Fedex or FEDEX. |
