Android database lazy loading method based on proxy mode

Abstract

The invention discloses an android database lazy loading method based on a proxy mode. The method includes the following steps that S100, proxy of a collection class is realized in the proxy mode, and a DAO layer in ORM visits a proxy object of the collection class; S200, a proxy class acts for an Iterator method of the collection class, and only when specific data are taken from a collection to call the Iterator method, does the proxy object fills up the collection by searching for a database. The utilization efficiency of the database is effectively improved, and the memory overhead of a system is effectively lowered.

Description

technical field

[0001] The invention relates to the technical field of computer networks, in particular to a proxy mode-based android database delay loading method. Background technique

[0002] ORMlite is a common ORM framework for operating sqlite databases. Due to its own characteristics, embedded devices need to be more cautious in utilizing system resources. Optimizations for ORMLite operations are also gaining attention.

[0003] When a persistent entity is initialized from the database, are the collection properties of the entity initialized along with the persistent class? If the collection attribute contains hundreds of thousands or even millions of records, the performance will drop sharply if all the collection attributes are fetched while the persistent entity is initialized. Contents of the invention

[0004] The object of the present invention is to provide a delay loading method for an android database based on a proxy mode, which can effectively improve t...
