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: float - execution duration in milliseconds.

set_references

Sets references to dependent components.

void setReferences(IReferences references)

• references: IReferences - references to locate the component dependencies.

trace

Records an operation trace with its name and duration

trace(context: Optional[IContext], component: str, operation: str, duration: float) void trace(IContext context, String component, String operation, Long duration)

• context: IContext - (optional) a context to trace execution through a call chain.
• component: String - a name of called component
• operation: String - a name of the executed operation.
• duration: Long - execution duration in milliseconds.

Examples

{@code
  public class MyComponent implements IReferenceable {
      private CompositeTracer _tracer = new CompositeTracer();
 
      @Override
      public void setReferences(IReferences references) throws ReferenceException, ConfigException {
          this._tracer.setReferences(references);
          // ...
      }
 
      public void myMethod(IContext context) {
          var timing = this._tracer.beginTrace(context, "mycomponent", "mymethod");
          try {
              // ...
              timing.endTrace();
          } catch (Exception err) {
              timing.endFailure(err);
          }
      }
  }
  }
