public RAFileOutputStream(java.io.RandomAccessFile parentFile, long startPos)
parentFile
- - underlying RandomAccess filestartPos
- - the (global) position of the first character in parentFileendPos
- - the (global) position of EOF mark (not a valid character in the file)public void write(int b) throws java.io.IOException
write
is that one byte is written
to the output stream. The byte to be written is the eight
low-order bits of the argument b
. The 24
high-order bits of b
are ignored.
Subclasses of OutputStream
must provide an
implementation for this method.
write
in class java.io.OutputStream
b
- the byte
.java.io.IOException
- if an I/O error occurs. In particular,
an IOException
may be thrown if the
output stream has been closed.public void write(byte[] b) throws java.io.IOException
b.length
bytes from the specified byte array
to this output stream. The general contract for write(b)
is that it should have exactly the same effect as the call
write(b, 0, b.length)
.write
in class java.io.OutputStream
b
- the data.java.io.IOException
- if an I/O error occurs.OutputStream.write(byte[], int, int)
public void write(byte[] b, int off, int len) throws java.io.IOException
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.write
in class java.io.OutputStream
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.java.io.IOException
