In PhixFlow, a text expression is made up from a string of characters inside double quotes, along with escape characters to insert special characters, for example quotes and line breaks. It can also include variable elements so that data from streams or other PhixFlow objects can be inserted into the string. The expression must evaluate to a fixed string.
Examples
| Required output | Text Expression |
|---|---|
| Completed | "Completed" |
| abc"def | Use single quotes if you want to embed a double quote (or visa versa) 'abc"def' or prefix the quote with a backslash "abc\"def" Note how this contrasts to the Regular Expression case, where a double-backslash is used to escape special characters. |
The account number ACC46242 failed | Generate a message including the current account number being processed, which is provided by _out.accountNumber: "The account number " + _out.accountNumber + " failed" |
This message is finished. | "This message\n" + "is finished." |
