stringToBytesNullTerminated

public static byte[] stringToBytesNullTerminated(String fileName)
Convert a String filename to a byte array using the deprecated ascii String method for cases where passing it through a character set converter is too heavyweight. Allocates an additional null-terminator byte so that the resulting byte array can be passed to native C functions.

Parameters:
fileName - File name
Returns:
Byte-array representation

stringToBytes

public static byte[] stringToBytes(String fileName)
Convert a String filename to a byte array using the deprecated ascii String method for cases where passing it through a character set converter is too heavyweight.

Parameters:
fileName - File name
Returns:
Byte-array representation

asciiBytesToString

public static String asciiBytesToString(byte[] val)
Convert a byte array to a String assuming the ASCII character set, for use in cases (such as early in the boot process) where character set conversion is unavailable or inadvisable.

Parameters:
val - Byte array to convert
Returns:
The resulting string

asciiBytesToString

public static String asciiBytesToString(byte[] val,
                                        int start,
                                        int length)
Convert a byte array to a String assuming the ASCII character set, for use in cases (such as early in the boot process) where character set conversion is unavailable or inadvisable.

Parameters:
val - Byte array to convert
start - Start the string at this byte
length - Use 'length' bytes
Returns:
The resulting string
