| Project: jackson-core |
| |
| Contains core streaming reader (`JsonParser`) and writer (`JsonGenerator`) abstractions, |
| factory for constructing readers/writers (JsonFactory), as well as a minimal set |
| of interfaces needed for streaming level to make callbacks and call-throughs, |
| via `ObjectCodec` and `TreeNode`. |
| |
| Also includes implementation of this API for JSON. |
| Forms the base for other data formats as well, despite naming that suggests |
| JSON-specificity: naming is due to history, as Jackson started out as pure |
| JSON library. |

| #137: Allow filtering content read via `JsonParser` by specifying `JsonPointer`; |
| uses new class `com.fasterxml.jackson.core.filter.FilteringParserDelegate` |
| (and related, `TokenFilter`) |
