WashingFilterInputStream
public WashingFilterInputStream(java.io.InputStream in)
- Creates a filtered input stream.
read
public int read()
throws java.io.IOException
- Reads in a character from the input stream. If the character is
less than 32 (Ascii space) or greater than 126 (Ascii tilde), it
is converted to a space. However, newlines, tabs, and carriage
returns (Ascii 9, 10, 13) are kept.
- Overrides:
read
in class java.io.FilterInputStream
java.io.IOException
read
public int read(byte[] buffer,
int off,
int len)
throws java.io.IOException
- Reads up to len bytes of data from this input stream into an
array of bytes. This method blocks until some input is available.
- Overrides:

in class java.io.FilterInputStream
java.io.IOException
washString
public static java.lang.String washString(java.lang.String s)
- Washes the contents of a single string.
main
public static void main(java.lang.String[] args)
throws java.io.IOException
- Washes a file and sends the results to stdout.
