ProxyReader (Cobble Lang 4.6.0 API)

所有已实现的接口:

Closeable, AutoCloseable, Readable

直接已知子类:

AutoCloseReader
```
public abstract class ProxyReader
extends FilterReader
```
A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
It is an alternative base class to FilterReader to increase reusability, because FilterReader changes the methods being called, such as read(char[]) to read(char[], int, int).

  - beforeRead
```
protected void beforeRead(int n)

```
    Invoked by the read methods before the call is proxied. The number of chars that the caller wanted to read (1 for the read() method, buffer length for read(char[]), etc.) is given as an argument.
    Subclasses can override this method to add common pre-processing functionality without having to override all the read methods. The default implementation does nothing.
    Note this method is not called from skip(long) or reset(). You need to explicitly override those methods if you want to add pre-processing steps also to them.
    
    参数:
    
    n - number of chars that the caller asked to be read
    
    抛出:
    
    IOException - if the pre-processing fails
    
    从以下版本开始:
    
    2.0
  - afterRead
```
protected void afterRead(int n)
                  throws IOException
```
    Invoked by the read methods after the proxied call has returned successfully. The number of chars returned to the caller (or -1 if the end of stream was reached) is given as an argument.
    Subclasses can override this method to add common post-processing functionality without having to override all the read methods. The default implementation does nothing.
    Note this method is not called from skip(long) or reset(). You need to explicitly override those methods if you want to add post-processing steps also to them.
    
    参数:
    
    n - number of chars read, or -1 if the end of stream was reached
    
    抛出:
    
    IOException - if the post-processing fails
    
    从以下版本开始:
    
    2.0
  - handleIOException
```
protected void handleIOException(IOException e)
                          throws IOException
```
    Handle any IOExceptions thrown.
    This method provides a point to implement custom exception handling. The default behaviour is to re-throw the exception.
    
    参数:
    
    e - The IOException thrown
    
    抛出:
    
    IOException - if an I/O error occurs
