GetSequenceFromLocalFile
Gets and updates sequence number stored in a local file.
This function is used to provide a monotonically increasing sequence number which can be used as a control number, for example in EDI. It does this by using a local file to store the current value of the sequence number. This file can be shared by any number of concurrent maps as it is protected using appropriate locking.
If the file is not present, it is automatically created and the sequence number starts with 1. The contents of the file is simply a ASCII encoded string with a numeric value, so it can be edited to use any desired sequence number.
Properties
| File path | Enter the path name of the local file. You may use ${propName} to substitute the value of a Java system property. For example, ${user.home}/control.txt uses the user.home (home directory) Java system property. |
