Java Interface Example

Java Interface Example

As an example, consider a document processor that accepts file input. The processor must implement the
CMXFileProcessor
class, which has the following method:
public String process( CMXContext context, String in, String additionalFilesDir, CMXEventReporter reporter) throws Exception
The meaning of the parameters is as follows:
Parameter
Description
context
Input parameter. An object containing the properties that the Script passes to the component. The
parameters
method of the object returns a vector containing the property values.
in
Input parameter. The full path of the file that the component operates on.
additionalFilesDir
Optional output parameter. The path of a temporary directory where the component writes files. At the end of processing, the Script deletes the entire directory content.
reporter
Input parameter. An object providing the report method, which the component can use to write events to the event log.
