Module tools.jackson.databind

Package tools.jackson.databind.ext

package tools.jackson.databind.ext

Contains extended support for "external" packages: things that may or may not be present in runtime environment, but that are commonly enough used so that explicit support can be added.

Currently included extensions are:

• Java core XML datatypes: the reason these are considered "external" is that some platforms that claim to be conformant are only partially so (Google Android, GAE) and do not included these types; and with Java 9 and above also due to JPMS reasons.
• Selected java.sql types.
• Selected java.beans annotations: @Transient, ConstructorProperties.
• Java (8) Time (JSR-310) type support: as of Jackson 3.0 included in databind but added similar to JacksonModules for improved configurability.
