NAME

       NetSDS::Util::Struct - data structure convertors

SYNOPSIS

	       use NetSDS::Util::Struct;

	       ...

	       my $str = dump_to_row($some_structure);

DESCRIPTION

       NetSDS::Util::Struct module contains different utilities for data structures processing.

EXPORTED METHODS

       dump_to_string(...)
	   Returns cleaned dump to scalar.

       dump_to_row(...)
	   Returns cleaned dump to scalar.

       to_array($data)
       arrays_to_hash($keys_ref, $values_ref) - translate arrays to hash
	   Parameters: references to keys array and values array

	   Return: hash

	   If @$keys_ref is longer than @$values_ref - rest of keys filled with "undef" values.

	   If @$keys_ref is shorter than @$values_ref - rest of values are discarded.

	   If any of parameters isn't array reference then "undef" will return.

	   Example:

		   my %h = array2hash(['fruit','animal'], ['apple','horse']);

	   Result should be a hash:

		   (
			   fruit => 'apple',
			   animal => 'horse'
		   )

       merge_hash($target, $source) - merge two hashes
	   Parameters: references to target and source hashes.

	   This method adds source hash to target one and return value as a result.

NAME

       NetSDS::Util::String - string prcessing routines

SYNOPSIS

	       use NetSDS::Util::String qw();

	       # Read from standard input
	       my $string = <STDIN>;

	       # Encode string to internal structure
	       $string = string_encode($tring);

DESCRIPTION

       "NetSDS::Util::String" module contains functions may be used to quickly solve string processing tasks like parsing, recoding, formatting.

       As in other NetSDS modules standard encoding is UTF-8.

EXPORTED FUNCTIONS

       str_encode($str[, $encoding]) - encode string to internal UTF-8
	   By default this function treat first argument as byte string in UTF-8 and return it's internal Unicode representation.

	   In case of external character set isn't UTF-8 it should be added as second argument of function.

		   # Convert UTF-8 byte string to internal Unicode representation
		   $uni_string = str_encode($byte_string);

		   # Convert KOI8-U byte string to internal
		   $uni_string = str_encode($koi8_string, 'KOI8-U');

	   After "str_encode()" it's possible to process this string correctly including regular expressions. All characters will be understood as
	   UTF-8 symbols instead of byte sequences.

       str_decode($str[, $encoding]) - decode internal UTF-8 to byte string
	   By default this function treat first argument as string in internal UTF-8 and return it in byte string (external) representation.

	   In case of external character set isn't UTF-8 it should be added as second argument of function.

		   # Get UTF-8 byte string from internal Unicode representation
		   $byte_string = str_decode($uni_string);

		   # Convert to KOI8-U byte string from internal Unicode
		   $koi8_string = str_encode($uni_string, 'KOI8-U');

	   It's recommended to use "str_encode()" when preparing data for communication with external systems (especially networking).

       str_recode($str, $FROM_ENC[, $TO_ENC]) - recode string
	   Translate string between different encodings.  If target encoding is not set UTF-8 used as default one.

       str_trim($str) - remove leading/trailing space characters
		   $orig_str = "  string with spaces   ";
		   $new_str = str_trim($orig_str);

		   # Output: "string with spaces"
		   print $new_str;

       str_trim_left($str) - removes leading whitespaces
	   This function is similar to "str_trim()" except of it removes only leading space characters and leave trailing ones.

       str_trim_right($str) - removes trailing whitespaces
	   This function is similar to "str_trim()" except of it removes only trailing space characters and leave leading ones.

       str_clean($str) - clean string from extra spaces
	   Function is similar to "str_trim()" but also changes all spacing chains inside string to single spaces.

       str_camelize($strin)
	   If pass undef - return undef.  If pass '' - return ''.

	   Examples:

		   # returns 'getValue'
		   str_camelize( 'get_value' )

		   # returns 'addUserAction'
		   str_camelize( 'ADD_User_actION' )

       str_decamelize(...)
	   If pass undef - return undef.  If pass '' - return ''.

	   Examples:

		   # returns 'get_value'
		   str_decamelize( 'getValue' )
