Method Summary

Modifier and TypeMethod and Description
public static boolean

Returns:

true if c represents a whitespace character in 8-bit US-ASCII
isWhitespace(byte
the 8-bit US-ASCII encoded character
c)

Determine if an 8-bit US-ASCII encoded character is represents whitespace

public static int

Returns:

the new start point
trimLeadingWhitespace(byte[]
the byte array containing the portion to trim whitespace for
raw, int
the start of the section of bytes
start, int
the end of the section of bytes
end)

raw, int
the start of the section of bytes
start, int
the end of the section of bytes
end)
