QueryTiming (Pentaho Community Edition Project: mondrian 9.3.0.0-424 API)

java.lang.Object
- mondrian.olap.QueryTiming

```
public class QueryTiming
extends Object
```
Provides hooks for recording timing information of components of Query execution.
NOTE: This class is experimental and subject to change/removal without notice.
Code that executes as part of a Query can call markStart(String) before executing, and markEnd(String) afterwards, or can track execution times manually and call markFull(String, long).
To read timing information, add a handler to the statement using Statement.enableProfiling(mondrian.spi.ProfileHandler) and implement the ProfileHandler.explain(String, QueryTiming) method.

public QueryTiming()
```
- Method Detail
  - init
```
public void init(boolean enabled)
```
    Initializes (or re-initializes) a query timing, also setting whether enabled. All previous stats are removed.
    
    Parameters:
    
    enabled - Whether to collect stats in future
  - done
```
public void done()
```
  - markStart
```
public final void markStart(String name)
```
    Marks the start of a Query component's execution.
    
    Parameters:
    
    name - Name of the component
  - markEnd
```
public final void markEnd(String name)
```
    Marks the end of a Query component's execution.
    
    Parameters:
    
    name - Name of the component
  - markFull
```
public final void markFull(String name,
                           long duration)
```
    Marks the duration of a Query component's execution. markFull is synchronized because it may be called from either Actor's spawn thread or RolapResultShepherd thread
    
    Parameters:
    
    name - Name of the component
    
    duration - Duration of the execution
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
