/** @file This library provides a set of utility APIs that allow to create/read/update/delete (CRUD) Redfish resources and provide basic query abilities by using [URI/RedPath] (https://github.com/DMTF/libredfish). The query language is based on XPath (https://www.w3.org/TR/1999/REC-xpath-19991116/). This library and query language essentially treat the entire Redfish Service like it was a single JSON document. In other words whenever it encounters an odata.id in JSON document, it will retrieve the new JSON document (if needed). We name the path as RedPath: Expression Description nodename Selects the JSON entity with the name "nodename". If the value of nodename is an object with "@odata.id", it will continue get the value from "@odata.id". / Selects from the root node [index] Selects the index number JSON entity from an array or object. If the JSON entity is one collection (has Members & Members@odata.count), means to get the index member in "Members". Index number >=1, 1 means to return the first instance. [XXX] Operation on JSON entity. If the JSON entity is one collection (has Members & Members@odata.count), means to get all elements in "Members". If the JSON entity is one array, means to get all elements in array. Others will match the nodename directly (e.g. JSON_OBJECT, JSON_STRING, JSON_TRUE, JSON_FALSE, JSON_INTEGER). [nodename] Selects all the elements from an JSON entity that contain a property named "nodename" [name=value] Selects all the elements from an JSON entity where the property "name" is equal to "value" [name~value] Selects all the elements from an JSON entity where the string property "name" is equal to "value" using case insensitive comparison. [namevalue] Selects all the elements from an JSON entity where the property "name" is greater than "value" [name>=value] Selects all the elements from an JSON entity where the property "name" is greater than or equal to "value" Some examples: /v1/Chassis[1] - Will return the first Chassis instance. /v1/Chassis[SKU=1234] - Will return all Chassis instances with a SKU field equal to 1234. /v1/Systems[Storage] - Will return all the System instances that have Storage field populated.
