JCoTraceListener (SAP Cloud Platform SDK for Neo Environment)

```
public interface JCoTraceListener
```
JCo trace listener interface. An application (server) implements this interface if it wants to intercept trace messages. Typically it is needed, if the JCo traces shall be redirected into a trace infrastructure so that it's interwoven with traces of layers above.

Field Summary

Fields
Modifier and Type	Field and Description
`static int`	`ERROR_WARNING` Includes errors and warnings.
`static int`	`ERRORS` Error information is written to trace.
`static int`	`FULL_DEBUG` Full trace.
`static int`	`FULL_PATH` Compared to `SHORT_DEBUG`, now all method invocations are traced (those that are traced at all).
`static int`	`INFO_PATH` The invocation of additional methods is added to trace compared to `PATH_API`.
`static int`	`INFO_PATH_API` Adds informational messages to trace in addition to errors and warnings.
`static int`	`NONE` No trace is written.
`static int`	`PATH_API` The invocation of API methods is added compared to `INFO_PATH_API`.
`static int`	`SHORT_DEBUG` Some more verbose information including limited data containers are added compared to `INFO_PATH`.
