## Constructor Details

### SuffixLines

public SuffixLines()
Constructor for "dummy" instances.

See Also:

### SuffixLines

public SuffixLines(Reader in)
Creates a new filtered reader.

Parameters:
  `in` - A Reader object providing the underlying stream. Must not be `null`.

## Method Details

### read

public int read() throws IOException
Returns the next character in the filtered stream. One line is read from the original input, and the suffix added. The resulting line is then used until it ends, at which point the next original line is read, etc.

Overrides:
  `read` in class `FilterReader`
Returns:
  the next character in the resulting stream, or -1 if the end of the resulting stream has been reached
Throws:
  `IOException` - if the underlying stream throws an IOException during reading

### setSuffix

public void setSuffix(String suffix)
Sets the suffix to add at the end of each input line.

Parameters:
  `suffix` - The suffix to add at the end of each input line. May be `null`, in which case no suffix is added.

### chain

public Reader chain(Reader rdr)
Creates a new SuffixLines filter using the passed in Reader for instantiation.

Specified by:
  `chain` in interface `ChainableReader`
Parameters:
  `rdr` - A Reader object providing the underlying stream. Must not be `null`.
Returns:
  a new filter based on this configuration, but filtering the specified reader
