toCheckedByteArray

public static byte[] toCheckedByteArray(java.lang.CharSequence s)

Converts the a CharSequence to a byte array, eliminating all the unprintable US-ASCII symbols by replacing them with spaces (' ').

Parameters:

s - CharSequence

Returns:

a converted byte array, where all the char sequence's unprintable US-ASCII symbols have been replaced with spaces (' ')

toCheckedByteArray

public static byte[] toCheckedByteArray(java.lang.CharSequence s,
                                        byte[] dstArray,
                                        int arrayOffs)

Serializes the passed CharSequence into a passed byte array starting from a given offset. All the unprintable US-ASCII symbols will be replaced with spaces (' ').

Parameters:

s - CharSequence

dstArray - the byte array to be used to convert the CharSequence into

arrayOffs - the offset in the byte array, where the serialization will be started

Returns:

the passed dstArray

Throws:

java.lang.IllegalArgumentException - if there is no enough space in the dstArray to serialize the CharSequence

isNonPrintableUsAscii

public static boolean isNonPrintableUsAscii(int ub)

Returns true if the passed symbol code represents a non-printable US-ASCII symbol in range [Integer.MIN_VALUE; 9) U (9; 31] U [127; Integer.MAX_VALUE].

Parameters:

ub - the symbol code to check

Returns:

true if the passed symbol code represents a non-printable US-ASCII symbol in range [Integer.MIN_VALUE; 9) U (9; 31] U [127; Integer.MAX_VALUE]
