| |
| The Zest™ Core Runtime has a number of extension points, which we call the _Qi4j Core Extension SPI_. These are defined |
| interfaces used *only* by the Core Runtime and *never* directly by application code. <<extensions>> are assembled in |
| applications during the bootstrap phase. |
| |
| include::../../build/docs/buildinfo/artifact.txt[] |
| |
| There are currently 5 Core SPI extensions; |
| |
| * <<core-spi-valueserialization>> |
| * <<core-spi-entitystore>> |
| * <<core-spi-cache>> |
| * <<core-spi-indexing>> |
| * <<core-spi-metrics>> |
| |
| Zest™ Runtime Extensions implementations may depend on Zest™ Libraries, but Libraries are NOT ALLOWED to depend on |
| Extensions. Applications code is NOT ALLOWED to depend on extensions. And application code SHOULD NOT depend on the |
| Core Extension SPI. If you think that is needed, please contact qi4j-dev forum at Google Groups, to see if your usecase |
| can be solved in a support manner, or that we need to extend the Core API to support it. |
