Method Detail

encodeTo

public static boolean encodeTo(String src,
               byte[] dest,
               int offs)

Encode a string into UTF-8 (except encoding character zero to its two-byte form).

Parameters:

src - the source string

dest - the array to encode to

offs - the offset into the destination array

Returns:

true if the string fit, false if it did not

encodedLengthOf

public static int encodedLengthOf(String src)

Get the encoded length of a string.

Parameters:

src - the string

Returns:

its encoded length

indexOf

public static int indexOf(byte[] array,
          int search,
          int offs,
          int len)

Find the first occurrence of a byte in a byte array.

Parameters:

array - the array to search

search - the byte to search for

offs - the offset in the array to start searching

len - the length of the segment to search

Returns:

the index, or -1 if the byte is not found

indexOf

public static int indexOf(byte[] array,
          int search,
          int offs)

Find the first occurrence of a byte in a byte array.

Parameters:

array - the array to search

search - the byte to search for

offs - the offset in the array to start searching

Returns:

the index, or -1 if the byte is not found

indexOf

public static int indexOf(byte[] array,
          int search)

Find the first occurrence of a byte in a byte array.

Parameters:

array - the array to search

search - the byte to search for

Returns:

the index, or -1 if the byte is not found
