close
public void close() throws java.io.IOException
- Specified by:
close
in interfacejava.lang.AutoCloseable
- Specified by:
close
in interfacejava.io.Closeable
- Overrides:
close
in classjava.io.FilterInputStream
- Throws:
java.io.IOException

getLog
public java.io.OutputStream getLog()
-
read
public int read() throws java.io.IOException
Reads the next byte of data from the input stream. The value byte is returned as anint
in the range0
to255
. If no byte is available because the end of the stream has been reached, the value-1
is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.A subclass must provide an implementation of this method.
- Overrides:
read
in classjava.io.FilterInputStream
- Returns:
- the next byte of data, or
-1
if the end of the stream is reached. - Throws:
java.io.IOException
- if an I/O error occurs.
-
read
public int read(byte[] b, int off, int len) throws java.io.IOException
Reads up tolen
bytes of data from this input stream into an array of bytes. This method blocks until some input is available.This method simply performs
in.read(b, off, len)
and returns the result.- Overrides:
read
in classjava.io.FilterInputStream
- Parameters:
b
- the buffer into which the data is read.off
- the start offset of the data.len
- the maximum number of bytes read.- Returns:
- the total number of bytes read into the buffer, or
-1
if there is no more data because the end of the stream has been reached. - Throws:
java.io.IOException
- if an I/O error occurs.- See Also:
