◆ deserialize()

bool dd::Foreign_key_element_impl::deserialize ( Sdi_rcontext rctx,
const RJ_Value val 
)
overridevirtual

Re-establishes the state of *this by reading sdi information from the rapidjson DOM subobject provided.

Cross-references encountered within this object are tracked in sdictx, so that they can be updated when the entire object graph has been established.

Parameters
rctxstores book-keeping information for the deserialization process
valsubobject of rapidjson DOM containing json representation of this object
Return values
falsesuccess
truefailure

◆ has_new_primary_key()

bool dd::Foreign_key_element_impl::has_new_primary_key ( ) const
overridevirtual

Indicates that object is guaranteed to have primary key value which doesn't exist in database (e.g.

because it only will be generated using auto-increment at store() time). So it is ok for store() method to skip lookup of existing object with the same primary key and simply try to insert new object into the table.

Converts *this into json.

Converts all member variables that are to be included in the sdi into json by transforming them appropriately and passing them to the rapidjson writer provided.

Parameters
wctxopaque context for data needed by serialization
wrapidjson writer which will perform conversion to json
