Constructor Summary

NonBlockingBufferedInputStream()

Method Summary

int	available() return the number of bytes available to be read without blocking
void	close() disassociate from the underlying input stream
int	peek() Just like read except byte is not removed from the buffer.
int	read() Read a byte from the input stream, blocking if necessary.
int	read(byte[] dest) Read bytes from the input stream.
int	read(byte[] dest, int off, int len) Read a specified number of bytes from the input stream.
void	setContentLength(int value) set the maximum number of bytes allowed to be read from this input stream.
void	setInputStream(java.io.InputStream in) set the input stream to be used for subsequent reads

Constructor Detail

NonBlockingBufferedInputStream

public NonBlockingBufferedInputStream()

Method Detail

setInputStream

public void setInputStream(java.io.InputStream in)

set the input stream to be used for subsequent reads

Parameters:

in - the InputStream

setContentLength

public void setContentLength(int value)

set the maximum number of bytes allowed to be read from this input stream.

Parameters:

value - the Content Length

read

public int read()
         throws java.io.IOException

Read a byte from the input stream, blocking if necessary. Internally the data is buffered for efficiency.

Specified by:

read in class java.io.InputStream

Returns:

the byte read

java.io.IOException

read

public int read(byte[] dest)
         throws java.io.IOException

Read bytes from the input stream. This is guaranteed to return at least one byte or throw an exception. When possible, it will return more bytes, up to the length of the array, as long as doing so would not require waiting on bytes from the input stream.

Overrides:

read in class java.io.InputStream

Parameters:

dest - byte array to read into

Returns:

the number of bytes actually read

java.io.IOException

read

public int read(byte[] dest,
                int off,
                int len)
         throws java.io.IOException

Read a specified number of bytes from the input stream. This is guaranteed to return at least one byte or throw an execption. When possible, it will return more bytes, up to the length specified, as long as doing so would not require waiting on bytes from the input stream.

Overrides:

read in class java.io.InputStream

Parameters:

dest - byte array to read into

off - starting offset into the byte array

len - maximum number of bytes to read

Returns:

the number of bytes actually read

java.io.IOException

skip

public int skip(int len)
         throws java.io.IOException

skip over (and discard) a specified number of bytes in this input stream

Parameters:

len - the number of bytes to be skipped

Returns:

the action number of bytes skipped

java.io.IOException

available

public int available()
              throws java.io.IOException

return the number of bytes available to be read without blocking

Overrides:

available in class java.io.InputStream

Returns:

the number of bytes

java.io.IOException

close

public void close()
           throws java.io.IOException

disassociate from the underlying input stream

Overrides:

close in class java.io.InputStream

java.io.IOException

peek

public int peek()
         throws java.io.IOException

Just like read except byte is not removed from the buffer. the data is buffered for efficiency. Was added to support multiline http headers. ;-)

Returns:

the byte read

java.io.IOException
