ZContext (JeroMQ 0.3.5 API)

java.lang.Object
- org.zeromq.ZContext

All Implemented Interfaces:

Closeable, AutoCloseable
```
public class ZContext
extends Object
implements Closeable
```
ZContext provides a high-level ZeroMQ context management class It manages open sockets in the context and automatically closes these before terminating the context. It provides a simple way to set the linger timeout on sockets, and configure contexts for number of I/O threads. Sets-up signal (interrupt) handling for the process.

```
- Method Detail
  - destroy
```
public void destroy()
```
    Destructor. Call this to gracefully terminate context and close any managed 0MQ sockets
  - createSocket
```
public ZMQ.Socket createSocket(int type)
```
    Creates a new managed socket within this ZContext instance. Use this to get automatic management of the socket at shutdown
    
    Parameters:
    type - socket type (see ZMQ static class members)
    
    Returns:
    Newly created Socket object
  - destroySocket
```
public void destroySocket(ZMQ.Socket s)
```
    Destroys managed socket within this context and remove from sockets list
    
    Parameters:
    s - org.zeromq.Socket object to destroy
  - shadow
```
public static ZContext shadow(ZContext ctx)
```
    Creates new shadow context. Shares same underlying org.zeromq.Context instance but has own list of managed sockets, io thread count etc.
    
    Parameters:
    ctx - Original ZContext to create shadow of
    
    Returns:
    New ZContext
  - getIoThreads
```
public int getIoThreads()
```
    Returns:
    the ioThreads
  - setIoThreads
```
public void setIoThreads(int ioThreads)
```
    Parameters:
    ioThreads - the ioThreads to set
  - getLinger
```
public int getLinger()
```
    Returns:
    the linger
  - setLinger
```
public void setLinger(int linger)
```
    Parameters:
    linger - the linger to set
  - getHWM
```
public int getHWM()
```
    Returns:
    the HWM
  - setHWM
```
public void setHWM(int hwm)
```
    Parameters:
    hwm - the HWM to set
  - isMain
```
public boolean isMain()
```
    Returns:
    the main
  - setMain
```
public void setMain(boolean main)
```
    Parameters:
    main - the main to set
  - getContext
```
public ZMQ.Context getContext()
```
    Returns:
    the context
  - setContext
```
public void setContext(ZMQ.Context ctx)
```
    Parameters:
    ctx - sets the underlying org.zeromq.Context associated with this ZContext wrapper object
  - getSockets
```
public List<ZMQ.Socket> getSockets()
```
    Returns:
    the sockets
