| 2 | // example custom verb that compiles to a <cfcase> tag |
|---|
| 3 | // usage: |
|---|
| 4 | // 1. add the lexicon declaration to your circuit file: |
|---|
| 5 | // <circuit xmlns:cf="cf/"> |
|---|
| 6 | // 2. use the verb in a fuseaction: |
|---|
| 7 | // <cf:switch expression="#someExpr#"> |
|---|
| 8 | // <cf:case value="someValue"> |
|---|
| 9 | // ... some code ... |
|---|
| 10 | // </cf:catch> |
|---|
| 11 | // <cf:case value="anotherValue|andAnother" delimiters="|"> |
|---|
| 12 | // ... more code ... |
|---|
| 13 | // </cf:case> |
|---|
| 14 | // <cf:defaultcase> |
|---|
