      • write

        public void write​(byte[] b,
                  int off,
                  int len)
           throws IOException
        Description copied from class: java.io.FilterOutputStream
        Writes len bytes from the specified byte array starting at offset off to this output stream.

        The write method of FilterOutputStream calls the write method of one argument on each byte to output.

        Note that this method does not call the write method of its underlying output stream with the same arguments. Subclasses of FilterOutputStream should provide a more efficient implementation of this method.

        Specified by:
        write in interface DataOutput
        Overrides:
        write in class FilterOutputStream
        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.

        FilterOutputStream.write(int)

      • writeBoolean

        public void writeBoolean​(boolean v)
                  throws IOException
        Description copied from interface: java.io.DataOutput
        Writes a boolean value to this output stream. If the argument v is true, the value (byte)1 is written; if v is false, the value (byte)0 is written. The byte written by this method may be read by the readBoolean method of interface DataInput, which will then return a boolean equal to v.
        Specified by:
        writeBoolean in interface DataOutput
        Parameters:
        v - the boolean to be written.
        Throws:
        IOException - if an I/O error occurs.

      • writeByte

        public void writeByte​(int v)
               throws IOException
        Description copied from interface: java.io.DataOutput
        Writes to the output stream the eight low- order bits of the argument v. The 24 high-order bits of v are ignored. (This means that writeByte does exactly the same thing as write for an integer argument.) The byte written by this method may be read by the readByte method of interface DataInput, which will then return a byte equal to (byte)v.
        Specified by:
        writeByte in interface DataOutput
        Parameters:
        v - the byte value to be written.
        Throws:
        IOException - if an I/O error occurs.

      • writeBytes

        @Deprecated
public void writeBytes​(String s)
                throws IOException
        Deprecated.
        The semantics of writeBytes(String s) are considered dangerous. Please use writeUTF(String s), writeChars(String s) or another write method instead.
        Description copied from interface: java.io.DataOutput
        Writes a string to the output stream. For every character in the string s, taken in order, one byte is written to the output stream. If s is null, a NullPointerException is thrown.

        If s.length is zero, then no bytes are written. Otherwise, the character s[0] is written first, then s[1], and so on; the last character written is s[s.length-1]. For each character, one byte is written, the low-order byte, in exactly the manner of the writeByte method . The high-order eight bits of each character in the string are ignored.

        Specified by:
        writeBytes in interface DataOutput
        Parameters:
        s - the string of bytes to be written.
        Throws:
        IOException - if an I/O error occurs.

      • writeUTF

        public void writeUTF​(String str)
              throws IOException
        Description copied from interface: java.io.DataOutput
        Writes two bytes of length information to the output stream, followed by the modified UTF-8 representation of every character in the string s. If s is null, a NullPointerException is thrown. Each character in the string s is converted to a group of one, two, or three bytes, depending on the value of the character.

        If a character c is in the range \u0001 through \u007f, it is represented by one byte: 

        (byte)c

        If a character c is \u0000 or is in the range \u0080 through \u07ff, then it is represented by two bytes, to be written in the order shown: 

        
 (byte)(0xc0 | (0x1f & (c >> 6)))
 (byte)(0x80 | (0x3f & c))

        If a character c is in the range \u0800 through uffff, then it is represented by three bytes, to be written in the order shown: 

        
 (byte)(0xe0 | (0x0f & (c >> 12)))
 (byte)(0x80 | (0x3f & (c >>  6)))
 (byte)(0x80 | (0x3f & c))

        First, the total number of bytes needed to represent all the characters of s is calculated. If this number is larger than 65535, then a UTFDataFormatException is thrown. Otherwise, this length is written to the output stream in exactly the manner of the writeShort method; after this, the one-, two-, or three-byte representation of each character in the string s is written.

        The bytes written by this method may be read by the readUTF method of interface DataInput , which will then return a String equal to s.

        Specified by:
        writeUTF in interface DataOutput
        Parameters:
        str - the string value to be written.
        Throws:
        IOException - if an I/O error occurs.
