Method Summary

Modifier and Type	Method and Description
static byte[]	getFixedSizeBytes(int fixedSize, String value) Get a fixed size byte array populated with the contents of a String If the String length is larger than the byte array, the String will be truncated to the fixed size
static void	writeFixedString(byte[] dest, String value, int offset, int fixedSize) Creates a fixed size byte array, populates it with contents of a String and writes this to a destination byte array
static void	writeInteger(byte[] dest, int value, int offset) Write an integer to a byte array

Method Detail

writeFixedString

public static void writeFixedString(byte[] dest,
                                    String value,
                                    int offset,
                                    int fixedSize)

Creates a fixed size byte array, populates it with contents of a String and writes this to a destination byte array

Parameters:

dest - the destination byte array

value - the String value

offset - the offset to write to in the destination array

fixedSize - the size of the byte array to place the String into

writeShort

public static void writeShort(byte[] dest,
                              short value,
                              int offset)

Write a short to a byte array

Parameters:

dest - the destination byte array

value - the short value to be written

offset - the offset to write to in the destination array

writeInteger

public static void writeInteger(byte[] dest,
                                int value,
                                int offset)

Write an integer to a byte array

Parameters:

dest - the destination byte array

value - the integer value to be written

offset - the offset to write to in the destination array

getFixedSizeBytes

public static byte[] getFixedSizeBytes(int fixedSize,
                                       String value)

Get a fixed size byte array populated with the contents of a String If the String length is larger than the byte array, the String will be truncated to the fixed size

Parameters:

fixedSize - the size of the byte array to place the String into

value - the String value

Returns:

the populated byte array
