hints
Description copied from interface:Generator
Hints provided by the generator to the engine.The most important hint for custom generators is
AfterGenerate
. This hint indicates whether the object created by this generator:- should be populated (for example, if it has
null
fields) - can be modified using selectors
For example, setting the hint to
AfterGenerate.POPULATE_NULLS
will cause Instancio to populatenull
fields on the object returned by this generator:@Override public Hints hints() { return Hints.afterGenerate(AfterGenerate.POPULATE_NULLS); }
If the action is not specified, default behaviour will be based on the
AfterGenerate
value configured in theSettings
using the keyKeys.AFTER_GENERATE_HINT
.In addition, the following hints can be provided for populating data structures:
- should be populated (for example, if it has
