DESCRIPTION

Library contains a group of useful utility functions

is_gco_error OBJECT

Returns true if OBJECT is an object (or sub-class) of "Google::Checkout::General::Error". Returns false otherwise. Many functions reteurns "Google::Checkout::General::Error" to indicate error conditions so it's important to use this function to check for them.

is_merchant_item OBJECT

Returns true if OBJECT is an object (or sub-class) of "Google::Checkout::General::MerchantItem". Returns false otherwise. This function is used internally.

is_shipping_method OBJECT

Returns true if OBJECT is an object (or sub-class) of "Google::Checkout::General::Shipping". Returns false otherwise. This function is used internally.

is_tax_table OBJECT

Returns true if OBJECT is an object (or sub-class) of "Google::Checkout::General::TaxTable". Returns false otherwise. This function is used internally.

compute_hmac_sha1 DATA, B64

Compute HMAC SHA1 for DATA. If B64 is true, also encode it in Base64 before returning.

compute_base64 DATA

Compute Base64 for DATA.

date_time_string DATE_TIME_STRING

Given a valid date/time string, return it in ISO 8601 UTC format. If string is not a valid date/time string, "Google::Checkout::General::Error" is returned.

make_xml_safe XML_DATA

Make XML_DATE safe to be used in a XML document. '&' is turned into '&#x26;', '>' is turned into '&#x3e;' and '<' is turned into '&#x3c;'.

format_tax_rate RATE

Make sure tax rate is in the right format. If RATE is less than 1, it's already in the right form so it's returned without any change. If RATE is equal to or greater than 1, it's assumed to be in percent format (for example, 25 means 25%) in which case it's turned into RATE / 100 (25 / 100 = 0.25).

get_valid_carrier CARRIER

Returns a valid carrier if CARRIER is valid. Returns "Google::Checkout::General::Error" otherwise. This function is used internally.

is_valid_buyer_info BUYER_INFO

This function is used internally.
