Constructor Detail
- XPRSprob
```
public XPRSprob()
         throws XPRSprobException
```
  Creates a new, empty problem. Note that instances of this class should be explicitly cleaned up by calling close() so that native resources can be released and licenses can be released. A good practice is to use instances of this class with try-with-resources.
  
  Throws:
  
  XPRSprobException - if the problem cannot be created.
- XPRSprob
```
public XPRSprob(java.lang.String path)
         throws XPRSprobException,
                XPRSexception
```
  Creates a new, empty problem. The functions calls XPRS.init(path) so you don't have to do that explicitly. Problems constructed this way will also take care of calling XPRS.free() to match the call to XPRS.init() made from this constructor. Note that instances of this class should be explicitly cleaned up by calling close() so that native resources can be released and licenses can be released. A good practice is to use instances of this class with try-with-resources.
  
  Parameters:
  
  path - The path to the license location for XPRS.init. This can be code null.
  
  Throws:
  
  XPRSexception - if the license cannot be initialized.
  
  XPRSprobException - if the problem cannot be created.
  
  Since:

Method Detail

close
```
public void close()
```
Destroy the problem, deallocating all memory used. Release any resources allocated for this problem instance. Also calls XPRS.free() to match the call to XPRS.init("") performed by the constructor.
