24.24 java.io.FilterInputStream (JDK 1.0)

This class provides method definitions required to filter data obtained from the InputStream specified when the FilterInputStream is created. It must be subclassed to perform some sort of filtering operation, and may not be instantiated directly. See the subclasses BufferedInputStream, DataInputStream, and PushbackInputStream.

public class FilterInputStream extends InputStream {
    // Protected Constructor
            protected FilterInputStream(InputStream in);
    // Protected Instance Variables
            protected InputStream in;
    // Public Instance Methods
            public int available() throws IOException;  // Overrides InputStream
            public void close() throws IOException;  // Overrides InputStream
            public synchronized void mark(int readlimit);  // Overrides InputStream
            public boolean markSupported();  // Overrides InputStream
            public int read() throws IOException;  // Defines InputStream
            public int read(byte[] b) throws IOException;  // Overrides InputStream
            public int read(byte[] b, int off, int len) throws IOException;  // Overrides InputStream
            public synchronized void reset() throws IOException;  // Overrides InputStream
            public long skip(long n) throws IOException;  // Overrides InputStream
}
