Method Detail

strlen

public static int strlen(byte[] input)

'Classic' strlen function. Obtain length of String from a given array of characters.

string2ByteArrayOf

public static byte[] string2ByteArrayOf(java.lang.String contents,
                                        int arraysize)

Convert String to byte[] of fixed max size.

Useful for interaction with AOS kernel, which uses fixed size Strings in its TOC entries.

There will always be a terminating null character, if the String does not fit then the result will be truncated. No more than contents.length() bytes will be copied, the result is padded with zero bytes (just like a C string).

Parameters:

contents - String contents to fill byte array

arraysize - Exact size of the resulting array.

Returns:

An array with at most the first arraysize-1 bytes from contents copied into it. The rest of the array is padded with zero bytes. The last byte of the array is always zero (C string style)

byteArray2String

public static java.lang.String byteArray2String(byte[] input)

Create string from byte[] but strip null-bytes from input.

Convert byte[] to String. If it has any trailing zero bytes then these are not part of the resulting String. This is different to what the String(byte[]) constructor does, because this constructor includes these zero bytes in the resulting String.

Parameters:

input - byte[] to convert to a String.

Returns:

new String with the contents of input represented as String.
