LoggingMatlabProxy (matconsolectl 4.4.2 API)

java.lang.Object
- matlabcontrol.MatlabProxy
- - matlabcontrol.LoggingMatlabProxy

All Implemented Interfaces:

MatlabOperations
```
public final class LoggingMatlabProxy
extends MatlabProxy
```
Wraps around a MatlabProxy to provide a log of interactions. The data is not altered. This logger is useful for determining the Java types and structure of data returned from MATLAB.

Interaction with all methods, except those defined in Object and not overridden, is logged. Entering a method, exiting a method, and throwing an exception are logged. Method parameters and return values are logged. The contents of a returned array will be recursively explored and its contents logged. As is convention, all of these interactions are logged at Level.FINER. If the logging system has not been otherwise configured, then the ConsoleHandler which prints log messages to the console will not show these log messages as their level is too low. To configure the ConsoleHandler to show these log messages, call showInConsoleHandler().

This class is unconditionally thread-safe.

4.1.0

    Constructs the logging proxy. All methods defined in MatlabProxy will be delegated to delegateProxy.
    
    Parameters:
    
    delegateProxy -
- Method Detail
  - showInConsoleHandler
```
public static void showInConsoleHandler()
```
    Configures the ConsoleHandler responsible for showing logging records to show the records that are logged by this proxy. This behavior is useful if you have not otherwise configured logging in your application.
  - eval
```
public void eval(String command)
          throws MatlabInvocationException
```
    Description copied from interface: MatlabOperations
    
    Evaluates a command in MATLAB. This is equivalent to MATLAB's eval('command').
    
    Parameters:
    
    command - the command to be evaluated in MATLAB
    
    Throws:
    
    MatlabInvocationException
  - returningEval
```
public Object[] returningEval(String command,
                              int nargout)
                       throws MatlabInvocationException
```
    Description copied from interface: MatlabOperations
    Evaluates a command in MATLAB, returning the result. This is equivalent to MATLAB's eval('command').
    
    In order for the result of this command to be returned the number of arguments to be returned must be specified by nargout. This is equivalent in MATLAB to the number of variables placed on the left hand side of an expression. For example, in MATLAB the inmem function may be used with either 1, 2, or 3 return values each resulting in a different behavior:
```
 
 M = inmem;
 [M, X] = inmem;
 [M, X, J] = inmem;
 
 
```
    The returned Object array will be of length nargout with each return argument placed into the corresponding array position.
    
    If the command cannot return the number of arguments specified by nargout then an exception will be thrown.
    Parameters:
    
    command - the command to be evaluated in MATLAB
    
    nargout - the number of arguments that will be returned from evaluating command
    
    Returns:
    
    result of MATLAB command, the length of the array will be nargout
    
    Throws:
    
    MatlabInvocationException
  - feval
```
public void feval(String functionName,
                  Object... args)
           throws MatlabInvocationException
```
    Description copied from interface: MatlabOperations
    
    Calls a MATLAB function with the name functionName, returning the result. Arguments to the function may be provided as args, but are not required if the function needs no arguments.
    
    The function arguments will be converted into MATLAB equivalents as appropriate. Importantly, this means that a String will be converted to a MATLAB char array, not a variable name.
    
    Parameters:
    
    functionName - the name of the MATLAB function to call
    
    args - the arguments to the function
    
    Throws:
    
    MatlabInvocationException
  - returningFeval
```
public Object[] returningFeval(String functionName,
                               int nargout,
                               Object... args)
                        throws MatlabInvocationException
```
    Description copied from interface: MatlabOperations
    Calls a MATLAB function with the name functionName, returning the result. Arguments to the function may be provided as args, but are not required if the function needs no arguments.
    
    The function arguments will be converted into MATLAB equivalents as appropriate. Importantly, this means that a String will be converted to a MATLAB char array, not a variable name.
    
    In order for the result of this function to be returned the number of arguments to be returned must be specified by nargout. This is equivalent in MATLAB to the number of variables placed on the left hand side of an expression. For example, in MATLAB the inmem function may be used with either 1, 2, or 3 return values each resulting in a different behavior:
```
 
 M = inmem;
 [M, X] = inmem;
 [M, X, J] = inmem;
 
 
```
    The returned Object array will be of length nargout with each return argument placed into the corresponding array position.
    
    If the function is not capable of returning the number of arguments specified by nargout then an exception will be thrown.
    Parameters:
    
    functionName - the name of the MATLAB function to call
    
    nargout - the number of arguments that will be returned by functionName
    
    args - the arguments to the function
    
    Returns:
    
    result of MATLAB function, the length of the array will be nargout
    
    Throws:
    
    MatlabInvocationException
  - setVariable
