Method Detail

javaShortToCShort

public static byte[] javaShortToCShort(short value)

Convert a Java short to C short.

javaIntToCUnsignedShort

public static byte[] javaIntToCUnsignedShort(int value)

Convert a Java int to a C unsigned short. A Java int is required because there are no unsigned integers in Java. Only the 2 low order bytes are sent.

javaIntToCInt

public static byte[] javaIntToCInt(int value)

Convert a Java int to a C int.

javaLongToCUnsignedInt

public static byte[] javaLongToCUnsignedInt(long value)

Convert a Java long to a C unsigned int. A Java long is required because there are no unsigned integers in Java. Only the 4 low order bytes are sent.

javaIntToCLong

public static byte[] javaIntToCLong(int value)

Convert a Java int to a C long (in C longs are only 4 bytes which is equivalent to a Java int)

javaLongToCUnsignedLong

public static byte[] javaLongToCUnsignedLong(long value)

Convert a Java long to a C unsigned long.

javaCharToCChar

public static byte javaCharToCChar(char value)

Convert a 2 byte Unicode character to a 1 byte C char

javaCharToCUnsignedChar

public static byte javaCharToCUnsignedChar(char value)

Convert a 2 byte Unicode character to a 1 byte unsigned C char

javaStringToCCharArray

public static byte[] javaStringToCCharArray(String value)

Convert a Java Unicode string to a C char array

cShortToJavaShort

public static short cShortToJavaShort(byte[] buffer)

Convert a C short to Java short.

Parameters:

buffer - byte array containing the c short value. The array must have a length >= 2. If the length > 2 only the first two bytes are used.

cUnsignedShortToJavaInt

public static int cUnsignedShortToJavaInt(byte[] buffer)

Convert a C unsigned short to Java int

cIntToJavaInt

public static int cIntToJavaInt(byte[] buffer)

Convert a C int to Java int

cUnsignedIntToJavaLong

public static long cUnsignedIntToJavaLong(byte[] buffer)

Convert a C unsigned int to Java long

cLongToJavaInt

public static int cLongToJavaInt(byte[] buffer)

Convert a C long to Java int

cUnsignedLongToJavaLong

public static long cUnsignedLongToJavaLong(byte[] buffer)

Convert a C unsigned long to Java long

cCharToJavaChar

public static char cCharToJavaChar(byte buffer)

Convert a C char to Java char

cUnsignedCharToJavaChar

public static char cUnsignedCharToJavaChar(byte buffer)

Convert a C unsigned char to Java char

cStringToJavaString

public static String cStringToJavaString(byte[] buffer)

Convert a C char array (string) to Java String

insertShiftInShiftOut

public static String insertShiftInShiftOut(String source)

Insert the shift in / shift out characters for Strings which contain DBCS characters.
