Dummy implementation of tracer that doesn’t do anything.
Implements: ITracer
Description
The NullTracer class allows you to create a dummy tracer with no real effect.
Important points
- It can be used in testing or in situations when tracing is required but must be disabled.
Instance methods
begin_trace
Begings recording an operation trace
TraceTiming beginTrace(IContext context, String component, String operation)
- context: IContext - (optional) a context to trace execution through a call chain.
- component: String - name of the called component
- operation: String - name of the executed operation.
- return: TraceTiming - a trace timing object.
failure
Records an operation failure with its name, duration and error
void failure(IContext context, String component, String operation, Exception error, long duration)
- context: IContext - (optional) a context to trace execution through a call chain.
- component: String - name of the called component
- operation: String - name of the executed operation.
- error: Exception - an error object associated with this trace.
- duration: long - execution duration in milliseconds.
trace
Records an operation trace with its name and duration.
void trace(IContext context, String component, String operation, Long duration)
- context: IContext - (optional) a context to trace execution through a call chain.
- component: String - name of the called component
- operation: String - name of the executed operation.
- duration: Long - execution duration in milliseconds.
