Method Detail

getModifiedUtf8Length

public static int getModifiedUtf8Length(java.lang.String string)

Returns the length of the modified UTF-8 byte array representation of the given string.

getModifiedUtf8Bytes

public static byte[] getModifiedUtf8Bytes(java.lang.String string)

Returns the modified UTF-8 byte array representation of the given string.

Note: surrogate pairs are encoded separately as three byte values as requested by the modified UTF-8 specification. This method is suited for encoding strings stored in class files, dex files or native libraries.

getString

public static java.lang.String getString(byte[] modifiedUtf8Bytes)

Returns the String representation of the given modified UTF-8 byte array.

getString

public static java.lang.String getString(byte[] modifiedUtf8Bytes,
                                         int startIndex,
                                         int endIndex)

Returns the String representation of the given modified UTF-8 byte array.

join

public static java.lang.String join(java.lang.String separator,
                                    java.lang.String... strings)

Joins the given strings using the provided separator.

Parameters:

separator - The separator to use.

strings - The strings to join.

Returns:

The input strings, concatenated together using the separator

toHexString

public static java.lang.String toHexString(byte[] bytes)

Returns the hexadecimal representation of the given byte array.

toHexString

public static java.lang.String toHexString(byte[] bytes,
                                           java.lang.String separator,
                                           boolean upperCase)

Returns the hexadecimal representation of the given byte array.

escapeControlCharacters

public static java.lang.String escapeControlCharacters(java.lang.String input)

Escapes control characters (\n, \r, \b, \t, \f).
