public final class LittleEndianDataOutputStream
extends java.io.FilterOutputStream
implements java.io.DataOutput

An implementation of DataOutput that uses little-endian byte ordering for writing char, short, int, float, double, and long values.

Note: This class intentionally violates the specification of its supertype DataOutput, which explicitly requires big-endian byte order.

Since:

8.0

Method Detail

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Specified by:

write in interface java.io.DataOutput

Overrides:

write in class java.io.FilterOutputStream

Throws:

java.io.IOException

writeBoolean

public void writeBoolean(boolean v)
                  throws java.io.IOException

Specified by:

writeBoolean in interface java.io.DataOutput

Throws:

java.io.IOException

writeByte

public void writeByte(int v)
               throws java.io.IOException

Specified by:

writeByte in interface java.io.DataOutput

Throws:

java.io.IOException

writeBytes

@Deprecated
public void writeBytes(java.lang.String s)
                throws java.io.IOException

Deprecated.

The semantics of writeBytes(String s) are considered dangerous. Please use writeUTF(String s), writeChars(String s) or another write method instead.

Specified by:

writeBytes in interface java.io.DataOutput

Throws:

java.io.IOException

writeChar

public void writeChar(int v)
               throws java.io.IOException

Writes a char as specified by DataOutputStream.writeChar(int), except using little-endian byte order.

Specified by:

writeChar in interface java.io.DataOutput

Throws:

java.io.IOException - if an I/O error occurs

writeChars

public void writeChars(java.lang.String s)
                throws java.io.IOException

Writes a String as specified by DataOutputStream.writeChars(String), except each character is written using little-endian byte order.

Specified by:

writeChars in interface java.io.DataOutput

Throws:

java.io.IOException - if an I/O error occurs

writeDouble

public void writeDouble(double v)
                 throws java.io.IOException

Writes a double as specified by DataOutputStream.writeDouble(double), except using little-endian byte order.

Specified by:

writeDouble in interface java.io.DataOutput

Throws:

java.io.IOException - if an I/O error occurs

writeFloat

public void writeFloat(float v)
                throws java.io.IOException

Writes a float as specified by DataOutputStream.writeFloat(float), except using little-endian byte order.

Specified by:

writeFloat in interface java.io.DataOutput

Throws:

java.io.IOException - if an I/O error occurs

writeInt

public void writeInt(int v)
