org.mule.transport.file

Class ExpressionFilenameParser

java.lang.Object

org.mule.transport.file.ExpressionFilenameParser

All Implemented Interfaces:

org.mule.api.context.MuleContextAware, FilenameParser

public class ExpressionFilenameParser
extends Object
implements FilenameParser, org.mule.api.context.MuleContextAware

ExpressionFilenameParser can use any expression language supported by Mule to construct a file name for the current message. Expressions can be xpath, xquery, ognl, mvel, header, function and more. For more information see http://www.mulesoft.org/documentation/display/MULE3USER/Using+Expressions.

For example an xpath expression can be defined to pull a message id out of an xml message and use that as the file name - #[xpath:/message/header/@id]

This parser superseeds the (now removed) org.mule.transport.file.SimpleFilenameParser which has been kept in Mule 2 for compatibility. The following demonstrates how to achieve the same results when using the ExpressionFilenameParser over the SimpleFilenameParser

• #[DATE] : #[function:datestamp]
• #[DATE:yy-MM-dd] : #[function:datestamp-yy-MM-dd]
• #[SYSTIME] : #[function:systime]
• #[UUID] : #[function:uuid]
• #[ORIGINALNAME] : #[header:inbound:originalFilename]
• #[COUNT] : #[function:count] - note that this is a global counter.
• #[<Message Property Name>] : #[header:<Message Property Name>]
