Function Documentation

Data bin2base64 (  Array< int >  data, bool  changeByteOrder, bool  padChar )

Convert data from binary format to base64 encoded string. Parameters: data  Data to convert. changeByteOrder  If set to *true* change order of bytes. padChar  Character which will be used to pad output. Default "=". (optional) Returns: converted to base64 encoded string.

Data bin2hex (  Array< int >  data, bool  changeByteOrder )

Convert data from binary format to hex string. Parameters: data  Data to convert. changeByteOrder  If set to *true* change order of bytes. Returns: converted to hex string.

Data bin2string (  Array< int >  data, bool  changeByteOrder, bool  asWideChar )

Convert data from binary format to string. Parameters: data  Data to convert. changeByteOrder  If set to *true* change order of bytes. asWideChar  - if set to *true*, this function will use 16 bits per char, otherwise only 8 bits per char will be used. Returns: converted to string.

int bitroll (  int  x, int  r )

Shifts bits in integer right, and perform rounding to 32 bits. Parameters: x  Integer to shift. r  How much shifts should be dome (must be lower than 32). Returns: Value of x w shifted right r times.

Array<int> changeByteOrder (  Array< int >  data  )

Changes order of bytes in data between big endian and low endian. Parameters: data  Data to change. Returns: Date with changed byte order.

int madd (  int  x, int  y )

Add two integer with rounding to 32 bits. Parameters: x  First sum argument. y  Second sum argument. Returns: Sum of x and y rounded to 32 bits.

Array<int> string2bin (  String  data, bool  changeByteOrder, bool  isWideChar )

Convert string to binary format. Parameters: data  String with data to convert. changeByteOrder  If true change order of bytes. isWideChar  If true, this function will use 16 bit per char, otherwise only 8 bit per char will be used. Returns: Data converted to binary format.
