Method Detail

byteAt

public static byte byteAt(byte[] value,
                          int index)

Return the byte at index in value.

Parameters:

value - Source value.

index - Zero-based index.

Returns:

The byte at index in value.

compareTo

public static int compareTo(byte[] value,
                            byte[] other)

Compare binary value with other binary value.

Parameters:

value - Source value.

other - Other string value for comparison.

Returns:

Negative result if value < other, zero result if value == other, positive result if value > other.

hashCode

public static int hashCode(byte[] value)

Return a hash code for value.

See Also:

PearsonHashing.

Parameters:

value - Source value.

Returns:

A hash code for `value`.

indexOf

public static int indexOf(byte[] value,
                          byte[] find)

See indexOf(byte[], byte[], int).

indexOf

public static int indexOf(byte[] value,
                          byte[] find,
                          int start)

Locates find within value, searching forwards from start.

See Also:

JavaScript String.prototype.indexOf.

Parameters:

value - Source value.

find - Text to be located.

start - Optional start position (defaults to 0).

Returns:

Zero-based index where `text` is found within `value`, or -1 if not found.

slice

public static byte[] slice(byte[] value,
                           int start)

See slice(byte[], int, int).

slice

public static byte[] slice(byte[] value,
                           int start,
                           int end)

Return a section of value beginning at start, through to end. Allows negative values for start / end to specify end-relative positions.

Parameters:

value - Source value.

start - The zero-based index at which to begin extraction from the source value. If negative, it is treated as value.length + start.

end - Optional. The zero-based index at which to end extraction from the source value. If omitted, slice extracts to the end of the value. If negative, it is treated as value.length + end.

Returns:

A section of value beginning at start, through to end. Allows negative values for start / end to specify end-relative positions.

toString

public static java.lang.String toString(byte[] value)

Return a string value with simple (numeric value) mapping of source bytes to target Unicode character values. Use only when character values are limited to ISO-8859-1 (the first 256 code points of Unicode).

See Also:

UTF8.toString.

Parameters:

value - Source value.

Returns:

A string value with simple (numeric value) mapping of source bytes to target Unicode character values. Use only when character values are limited to [ISO-8859-1](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) (the first 256 code points of Unicode).
