public int read(final byte[] b, final int off, final int len) throws IOException Overrides java.io.InputStream.read. Doc from java.io.InputStream.read. Reads up to `len` bytes of data from the input stream into an array of bytes. An attempt is made to read as many as `len` bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown. If `len` is zero, then no bytes are read and `0` is returned; otherwise, there is an attempt to read at least one byte. If no byte is available because the stream is at end of file, the value `-1` is returned; otherwise, at least one byte is read and stored into `b`. The first byte read is stored into element `b[off]`, the next one into `b[off+1]`, and so on. The number of bytes read is, at most, equal to `len`. Let k be the number of bytes actually read; these bytes will be stored in elements `b[off]` through `b[off+`k`-1]`, leaving elements `b[off+`k`]` through `b[off+len-1]` unaffected. In every case, elements `b[0]` through `b[off-1]` and elements `b[off+len]` through `b[b.length-1]` are unaffected. Parameters b:byte[] the buffer into which the data is read. off:int the start offset in array `b` at which the data is written. len:int the maximum number of bytes to read. Returns:int 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. Annotations @SuppressWarnings:resource @Override Exceptions IOException: If the first byte cannot be read for any reason other than end of file, or if the input stream has been closed, or if some other I/O error occurs.

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

In every case, elements b[0] through b[off-1] and elements b[off+len] through b[b.length-1] are unaffected.

Parameters

b:byte[]: the buffer into which the data is read.
off:int: the start offset in array b at which the data is written.

public void write(final byte[] b, final int off, final int len) throws IOException Overrides java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes `len` bytes from the specified byte array starting at offset `off` to this output stream. The general contract for `write(b, off, len)` is that some of the bytes in the array `b` are written to the output stream in order; element `b[off]` is the first byte written and `b[off+len-1]` is the last byte written by this operation. If `b` is `null`, a `NullPointerException` is thrown. If `off` is negative, or `len` is negative, or `off+len` is greater than the length of the array `b`, then an `IndexOutOfBoundsException` is thrown. Parameters b:byte[] the data. off:int the start offset in the data. len:int the number of bytes to write. Annotations @Override Exceptions IOException: if an I/O error occurs. In particular, an `IOException` is thrown if the output stream is closed.

public void write(final byte[] b, final int off, final int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

off:int: the start offset in the data.
len:int: the number of bytes to write.
