Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`int`	`getActiveTaskCount()` Returns the approximate number of threads that are actively executing tasks.
`long`	`getCompletedTaskCount()` Returns the approximate total number of tasks that have completed execution.
`int`	`getCorePoolSize()` Returns core pool size of thread pool, the minimum number of workers (where that makes sense for a thread pool, SEPExecutor does not have a minimum size).
`int`	`getMaximumPoolSize()` Returns maximum pool size of thread pool.
`default int`	`getMaxTasksQueued()`
`int`	`getPendingTaskCount()` Returns the approximate total of tasks waiting to be executed.
`void`	`setCorePoolSize(int newCorePoolSize)` Allows user to resize minimum size of the thread pool.
`void`	`setMaximumPoolSize(int newMaximumPoolSize)` Allows user to resize maximum size of the thread pool.

- Method Detail
  - getCorePoolSize
```
int getCorePoolSize()
```
    Returns core pool size of thread pool, the minimum number of workers (where that makes sense for a thread pool, SEPExecutor does not have a minimum size).
  - setCorePoolSize
```
void setCorePoolSize(int newCorePoolSize)
```
    Allows user to resize minimum size of the thread pool.
  - getMaximumPoolSize
```
int getMaximumPoolSize()
```
    Returns maximum pool size of thread pool.
  - setMaximumPoolSize
```
void setMaximumPoolSize(int newMaximumPoolSize)
```
    Allows user to resize maximum size of the thread pool.
  - getActiveTaskCount
```
int getActiveTaskCount()
```
    Returns the approximate number of threads that are actively executing tasks.
    
    Returns:
    
    the number of threads
  - getCompletedTaskCount
```
long getCompletedTaskCount()
```
    Returns the approximate total number of tasks that have completed execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.
    
    Returns:
    
    the number of tasks
  - getPendingTaskCount
```
int getPendingTaskCount()
```
    Returns the approximate total of tasks waiting to be executed. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation.
    
    Returns:
    
    the number of tasks
  - getMaxTasksQueued
```
default int getMaxTasksQueued()
```
