Inherited methods
From: ByteSink
public default void write(int b) throws IOException
Overridden from: ByteSink
Writes a single byte to the byte sink.

This method works similarly to OutputStream.write(int).

bThe byte.
IOExceptionIn case of I/O error.
public abstract void write(byte[] b) throws IOException
Overridden from: DataOutput
Writes to the output stream all the bytes in array b. If b is null, a NullPointerException is thrown. If b.length is zero, then no bytes are written. Otherwise, the byte b[0] is written first, then b[1], and so on; the last byte written is b[b.length-1].

IOExceptionif an I/O error occurs.
public abstract void write(byte[] b, int off, int len) throws IOException
Overridden from: DataOutput
Writes len bytes from array b, in order, to the output stream. 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. If len is zero, then no bytes are written. Otherwise, the byte b[off] is written first, then b[off+1], and so on; the last byte written is b[off+len-1].

public abstract void writeBoolean(boolean v) throws IOException
Overridden from: 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.
vthe boolean to be written.
IOExceptionif an I/O error occurs.
public abstract void writeByte(int v) throws IOException
Overridden from: 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.
vthe byte value to be written.
IOExceptionif an I/O error occurs.
Overridden from: 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.

IOExceptionif an I/O error occurs.
public abstract void writeChar(int v) throws IOException
Overridden from: DataOutput
Writes a char value, which is comprised of two bytes, to the output stream. The byte values to be written, in the order shown, are:

 (byte)(0xff & (v >> 8))
 (byte)(0xff & v)
 

The bytes written by this method may be read by the readChar method of interface DataInput , which will then return a char equal to (char)v.

vthe char value to be written.
IOExceptionif an I/O error occurs.
Overridden from: DataOutput
Writes every character in the string s, to the output stream, in order, two bytes per character. If s is null, a NullPointerException is thrown. If s.length is zero, then no characters 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, two bytes are actually written, high-order byte first, in exactly the manner of the writeChar method.

public abstract void writeDouble(double v) throws IOException
Overridden from: DataOutput
Writes a double value, which is comprised of eight bytes, to the output stream. It does this as if it first converts this double value to a long in exactly the manner of the Double.doubleToLongBits method and then writes the long value in exactly the manner of the writeLong method. The bytes written by this method may be read by the readDouble method of interface DataInput, which will then return a double equal to v.
vthe double value to be written.
IOExceptionif an I/O error occurs.
public abstract void writeFloat(float v) throws IOException
Overridden from: DataOutput
Writes a float value, which is comprised of four bytes, to the output stream. It does this as if it first converts this float value to an int in exactly the manner of the Float.floatToIntBits method and then writes the int value in exactly the manner of the writeInt method. The bytes written by this method may be read by the readFloat method of interface DataInput, which will then return a float equal to v.
vthe float value to be written.
IOExceptionif an I/O error occurs.
public abstract void writeInt(int v) throws IOException
Overridden from: DataOutput
Writes an int value, which is comprised of four bytes, to the output stream. The byte values to be written, in the order shown, are:

 (byte)(0xff & (v >> 24))
 (byte)(0xff & (v >> 16))
 (byte)(0xff & (v >>  8))
 (byte)(0xff & v)
 

The bytes written by this method may be read by the readInt method of interface DataInput , which will then return an int equal to v.

vthe int value to be written.
IOExceptionif an I/O error occurs.
public abstract void writeLong(long v) throws IOException
Overridden from: DataOutput
Writes a long value, which is comprised of eight bytes, to the output stream. The byte values to be written, in the order shown, are:

 (byte)(0xff & (v >> 56))
 (byte)(0xff & (v >> 48))
 (byte)(0xff & (v >> 40))
 (byte)(0xff & (v >> 32))
 (byte)(0xff & (v >> 24))
 (byte)(0xff & (v >> 16))
 (byte)(0xff & (v >>  8))
 (byte)(0xff & v)
 

The bytes written by this method may be read by the readLong method of interface DataInput , which will then return a long equal to v.

IOExceptionif an I/O error occurs.
public abstract void writeShort(int v) throws IOException
Overridden from: DataOutput
Writes two bytes to the output stream to represent the value of the argument. The byte values to be written, in the order shown, are:

 (byte)(0xff & (v >> 8))
 (byte)(0xff & v)
 

The bytes written by this method may be read by the readShort method of interface DataInput , which will then return a short equal to (short)v.

vthe short value to be written.
IOExceptionif an I/O error occurs.
public abstract void writeUTF(String s) throws IOException
Overridden from: 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.
