TTMSFNCCustomCloudGoogleFireBaseObjectDatabase Class

Provides an object-oriented layer over a cloud realtime database that stores, retrieves, queries, and deletes typed TTMSFNCCloudGoogleFireBaseObject records. Objects are serialized to the database and reconstructed into their original type when read back.

API unit family: TMSFNCCloudGoogleFireBaseObject Inherits from: TTMSFNCCustomCloudGoogleFireBase

Syntax

TTMSFNCCustomCloudGoogleFireBaseObjectDatabase = class(TTMSFNCCustomCloudGoogleFireBase)

Remarks

This is the non-published base class. Use the published descendant for design-time use. Single-object operations work on one record at a time, while the list operations process whole collections; the query operations filter records by a property value or value range.

Methods

Name	Description
DeleteList	Deletes every record that matches an object in the list.
DeleteObject	Deletes the record identified by the given key.
InsertList	Inserts every object in the list as a new record, generating identifiers for items that do not yet have one.
InsertObject	Inserts a new object as a record in the database. When the object has no identifier, a unique one is generated before insertion.
QueryList	Queries records whose named property equals the given string value.
ReadList	Reads all records from the database. The parsed result is delivered through the read-data-list event.
ReadObject	Reads a single record by identifier. The result is delivered asynchronously through the read-data callbacks.
WriteList	Writes every object in the list to the database.
WriteObject	Writes an object to the database, updating the existing record that matches its identifier.
