Executor (Jenkins core 2.331 API)

java.lang.Object
- java.lang.Thread
- - hudson.model.Executor

All Implemented Interfaces:

ModelObject, Runnable

Direct Known Subclasses:

OneOffExecutor
```
@ExportedBean
public class Executor
extends Thread
implements ModelObject
```
Thread that executes builds. Since 1.536, Executors start threads on-demand.
Callers should use isActive() instead of Thread.isAlive().

All Methods Static Methods Instance Methods Concrete Methods Deprecated Methods
Modifier and Type	Method and Description
`Result`	`abortResult()`
`void`	`completedAsynchronous(Throwable error)`
`static Executor`	`currentExecutor()` Returns the executor of the current thread or null if current thread is not an executor.
`org.kohsuke.stapler.HttpResponse`	`doStop()` Stops the current build. You can use `doStopBuild(String)` instead to ensure what will be interrupted is actually what you want to interrupt.
`void`	`doStop(org.kohsuke.stapler.StaplerRequest req, org.kohsuke.stapler.StaplerResponse rsp)` Deprecated. as of 1.489 Use `doStop()` or `doStopBuild(String)`.
`org.kohsuke.stapler.HttpResponse`	`doStopBuild(String runExtId)` Stops the current build, if matching the specified external id (or no id is specified, or the current `Queue.Executable` is not a `Run`).
`org.kohsuke.stapler.HttpResponse`	`doYank()` Deprecated. now a no-op
`Api`	`getApi()` Exposes the executor to the remote API.
`AsynchronousExecution`	`getAsynchronousExecution()` If currently running in asynchronous mode, returns that handle.
`Throwable`	`getCauseOfDeath()` Deprecated. no longer used
`Collection<CauseOfInterruption>`	`getCausesOfInterruption()` Returns causes of interruption.
`Queue.Executable`	`getCurrentExecutable()` Returns the current build this executor is running.
`Queue.Executable`	`getCurrentExecutableForApi()` Same as `getCurrentExecutable()` but checks `Item.READ`.
`FilePath`	`getCurrentWorkspace()` If current executable is `AbstractBuild`, return the workspace that this executor is using, or null if the build hasn't gotten to that point yet.
`WorkUnit`	`getCurrentWorkUnit()` Returns the current `WorkUnit` (of `the current executable`) that this executor is running.
`String`	`getDisplayName()` Human readable name of the Jenkins executor.
`long`	`getElapsedTime()`
`static long`	`getEstimatedDurationFor(Queue.Executable e)` Deprecated. call `Queue.Executable.getEstimatedDuration()` directly
`String`	`getEstimatedRemainingTime()` Computes a human-readable text that shows the expected remaining time until the build completes.
`long`	`getEstimatedRemainingTimeMillis()` The same as `getEstimatedRemainingTime()` but return it as a number of milli-seconds.
`long`	`getIdleStartMilliseconds()` Returns when this executor started or should start being idle.
`int`	`getNumber()` Gets the executor number that uniquely identifies it among other `Executor`s for the same computer.
`Computer`	`getOwner()`
`int`	`getProgress()` Returns the progress of the current build in the number between 0-100.
`long`	`getTimeSpentInQueue()` Returns the number of milli-seconds the currently executing job spent in the queue waiting for an available executor.
`String`	`getTimestampString()` Gets the string that says how long since this build has started.
`boolean`	`hasStopPermission()` Checks if the current user has a permission to stop this build.
`void`	`interrupt()`
`void`	`interrupt(Result result)` Interrupt the execution, but instead of marking the build as aborted, mark it as specified result.
`void`	`interrupt(Result result, CauseOfInterruption... causes)` Interrupt the execution.
`boolean`	`isActive()` Check if executor is ready to accept tasks.
`boolean`	`isBusy()` The opposite of `isIdle()` — the executor is doing some work.
`boolean`	`isDisplayCell()` If this executor is running an `AsynchronousExecution` and that execution wants to hide the display cell for the executor (because there is another executor displaying the job progress and we don't want to confuse the user) then this method will return `false` to indicate to `executors.jelly` that the executor cell should be hidden.
`boolean`	`isIdle()` Returns true if this `Executor` is ready for action.
`boolean`	`isLikelyStuck()` Returns true if the current build is likely stuck.
`boolean`	`isParking()` Returns true if this executor is waiting for a task to execute.
`<T> T`	`newImpersonatingProxy(Class<T> type, T core)` Creates a proxy object that executes the callee in the context that impersonates this executor.
`static Executor`	`of(Queue.Executable executable)` Finds the executor currently running a given process.
`void`	`recordCauseOfInterruption(Run<?,?> build, TaskListener listener)` report cause of interruption and record it to the build, if available.
`void`	`run()`
`void`	`start()` Can't start executor like you normally start a thread.

    The opposite of isIdle() — the executor is doing some work.
  - isActive
```
public boolean isActive()
```
    Check if executor is ready to accept tasks. This method becomes the critical one since 1.536, which introduces the on-demand creation of executor threads. Callers should use this method instead of Thread.isAlive(), which would be incorrect for non-started threads or running AsynchronousExecution.
    
    Returns:
    
    true if the executor is available for tasks (usually true)
    
    Since:
    
    1.536

```
public boolean isDisplayCell()

    -1 if it's impossible to estimate the progress.
  - isLikelyStuck
```
@Exported
public boolean isLikelyStuck()
```
    Returns true if the current build is likely stuck.
    This is a heuristics based approach, but if the build is suspiciously taking for a long time, this method returns true.
  - getElapsedTime
```
public long getElapsedTime()
```
  - getTimeSpentInQueue
```
public long getTimeSpentInQueue()
```
    Returns the number of milli-seconds the currently executing job spent in the queue waiting for an available executor. This excludes the quiet period time of the job.

```
    Computes a human-readable text that shows the expected remaining time until the build completes.
  - getEstimatedRemainingTimeMillis
```
public long getEstimatedRemainingTimeMillis()
```
    The same as getEstimatedRemainingTime() but return it as a number of milli-seconds.
  - start
```
public void start()
```
    Can't start executor like you normally start a thread.

    Creates a proxy object that executes the callee in the context that impersonates this executor. Useful to export an object to a remote channel.
  - currentExecutor
```
@CheckForNull
public static Executor currentExecutor()
```
    Returns the executor of the current thread or null if current thread is not an executor.
  - of
```
@CheckForNull
public static Executor of(Queue.Executable executable)

    Finds the executor currently running a given process.
    
    Parameters:
    
    executable - a possibly running executable
    
    Returns:
    
    the executor (possibly a OneOffExecutor) whose getCurrentExecutable() matches that, or null if it could not be found (for example because the execution has already completed)
