All Implemented Interfaces:

Closeable, AutoCloseable

public final class ConstrainableInputStream
extends BufferedInputStream

A jsoup internal class (so don't use it as there is no contract API) that enables constraints on an Input Stream, namely a maximum read size, and the ability to Thread.interrupt() the read.

Constructor Details

ConstrainableInputStream

private ConstrainableInputStream(InputStream in,
 int bufferSize,
 int maxSize)

Method Details

wrap

public static ConstrainableInputStream wrap(InputStream in,
 int bufferSize,
 int maxSize)

If this InputStream is not already a ConstrainableInputStream, let it be one.

Parameters:

in - the input stream to (maybe) wrap

bufferSize - the buffer size to use when reading

maxSize - the maximum size to allow to be read. 0 == infinite.

Returns:

a constrainable input stream

read

public int read(byte[] b,
 int off,
 int len)
         throws IOException

Overrides:

read in class BufferedInputStream

Throws:

IOException

readToByteBuffer

public ByteBuffer readToByteBuffer(int max)
                            throws IOException

Reads this inputstream to a ByteBuffer. The supplied max may be less than the inputstream's max, to support reading just the first bytes.

Throws:

IOException

reset

public void reset()
           throws IOException

Overrides:

reset in class BufferedInputStream

Throws:

IOException

timeout

public ConstrainableInputStream timeout(long startTimeNanos,
 long timeoutMillis)

expired

private boolean expired()
