read()
Reads one byte from this buffer.

int len)
Reads up to
len bytes of data from this buffer into
an array of bytes. |

int read(byte[] b, int off, int len) throws IOException
len
bytes of data from this buffer into
an array of bytes. The exact number of bytes read depends how many bytes
are stored in the buffer.
If off
is negative, or len
is negative, or
off+len
is greater than the length of the array
b
, this method can throw a runtime exception. The exact type
of runtime exception thrown by this method depends on implementation.
This method returns -1
if the end of content stream has been
reached.
b
- the buffer into which the data is read.off
- the start offset in array b
at which the data is written.len
- the maximum number of bytes to read.-1
if there is no more data because the end of
the stream has been reached.IOException
- if an I/O error occurs.int read() throws IOException
-1
if the end of content stream has been reached.IOException
- in case of an I/O error.Copyright © 2005–2021 The Apache Software Foundation. All rights reserved.
