- - com.ibm.streams.operator.logging.TraceLevel

All Implemented Interfaces:: java.io.Serializable

public class TraceLevel
extends java.util.logging.Level

Convenience class to provide SPL trace levels through the java.util.logging facility.
The SPL trace levels in descending order are:

ERROR (highest value)
WARN
INFO
DEBUG
TRACE (lowest value)

When a message is logged to the SPL trace facility its java.util.logging.Level is mapped to the SPL trace level as follows:

***SPL trace level mapping***
SPL Trace Level	`java.util.logging.Level`

`error`	`Level.SEVERE`
	`ERROR`
	`>= 1000`
`warn`	`Level.WARNING`
	`WARN`
	`>= 900 AND < 1000`
`info`	`Level.INFO`
	`Level.CONFIG`
	`INFO`
	`>= 700 AND < 900`
`debug`	`Level.FINE`
	`Level.FINER`
	`DEBUG`
	`>= 400 AND < 700`
`trace`	`Level.FINEST`
	`TRACE`
	`< 400`

Field Summary

Fields
Modifier and Type	Field and Description
`static TraceLevel`	`DEBUG` DEBUG is a message level for debug level tracing information including method entry, exit, and return values.
`static TraceLevel`	`ERROR` ERROR is a level indicating the operator cannot continue.
`static java.lang.String`	`IBM_COPYRIGHT`
`static TraceLevel`	`INFO` INFO is level indicating general information outlining overall operator progress.
`static TraceLevel`	`TRACE` TRACE is a level for more detailed trace that includes all the detail that is needed to debug problems.
`static TraceLevel`	`WARN` WARN is a level indicating a potential error or impending error.

    Constant Field Values
  - ERROR
```
public static final TraceLevel ERROR
```
    ERROR is a level indicating the operator cannot continue. All internal or unexpected failures should be traced at this level. This level is initialized to 1000 and is equal to Level.SEVERE.
  - WARN
```
public static final TraceLevel WARN
```
    WARN is a level indicating a potential error or impending error. This level can also indicate a progressive failure (for example, the potential leaking of resources). This level is initialized to 900 and is equal to Level.WARNING.
  - INFO
```
public static final TraceLevel INFO
```
    INFO is level indicating general information outlining overall operator progress. Information that helps to give context to a trace, often when an operator is being initialized, handling allPortsReady() or being shutdown. This level is initialized to 700 and is equal to Level.CONFIG.
  - DEBUG
```
public static final TraceLevel DEBUG
```
    DEBUG is a message level for debug level tracing information including method entry, exit, and return values. This level is initialized to 400 and is equal to Level.FINER.
  - TRACE
```
public static final TraceLevel TRACE
```
    TRACE is a level for more detailed trace that includes all the detail that is needed to debug problems. This level is initialized to 300 and is equal to Level.FINEST.
