write
The same behavior as OutputStream.write().
Writes the specified byte to this output stream. The general contract forwrite
is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argumentb
. The 24 high-order bits ofb
are ignored.Subclasses of
OutputStream
must provide an implementation for this method.- Specified by:
write
in classOutputStream
- Parameters:
b
- thebyte
.- Throws:
IOException
- if an I/O error occurs. In particular, anIOException
may be thrown if the output stream has been closed.
-
write
Writesb.length
bytes from the specified byte array to this output stream. The general contract forwrite(b)
is that it should have exactly the same effect as the callwrite(b, 0, b.length)
.- Overrides:
write
in classOutputStream
- Parameters:
b
- the data.- Throws:
IOException
- if an I/O error occurs.- See Also:
-
write
Writeslen
bytes from the specified byte array starting at offsetoff
to this output stream. The general contract forwrite(b, off, len)
is that some of the bytes in the arrayb
are written to the output stream in order; elementb[off]
is the first byte written andb[off+len-1]
is the last byte written by this operation.- Overrides:
write
in classOutputStream
- Parameters:
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.- Throws:
IOException
- if an I/O error occurs.
-
writeInt
Same behavior as DataOutputStream.writeInt();- Specified by:
writeInt
in classRAOutputStream
- Throws:
IOException
-
writeLong
Same behavior as DataOutputStream.writeLong();- Specified by:
writeLong
in classRAOutputStream
- Throws:
IOException
-
getOffset
- Specified by:
getOffset
in classRAOutputStream
- Throws:
IOException
-
seek
Same behavior as the seek in RandomAccessFile.
Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs. The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.- Specified by:
seek
in classRAOutputStream
- Parameters:
localPos
- - the new local postion in the stream, measured in bytes from the beginning of the stream- Throws:
IOException
-
flush
Flush the stream.- Specified by:
flush
in interfaceFlushable
- Overrides:
flush
in classOutputStream
- Throws:
IOException
-
close
Close the stream. If the stream is the only one in the underlying file, the file will be close too.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Overrides:
close
in classOutputStream
- Throws:
IOException
-
length
- Specified by:
length
in classRAOutputStream
