nimn4j-annotations

Core annotations require to parse a Java object to Nimn format and vice versa (under draft)

Annotations

Class level

• @Nimn
• @Nimn(sequence=["","",""]): specify sequence of properties so that changing the order of fields in the class will not effect encoding /decoding
• @NimnIgnoreProperties({"property1", "property2"})
• @NimnIgnoreProperties(ignoreExtra=true): Application will not throw error when nimn has data for a field which is not present in annotated class.

Field level

@NimnParser(parser.class): Helpful when

• passwords or sensetive information need to be encrypted/decrypted
• when schema level encoding / decoding applies. Like for date/enum etc.

@NimnIgnore: An annotated field will be ignored. IDE plugin will also not warn.

@NimnUnique : annotated field will not be separated with boundary char. Allowed on enum or boolean type values only.

If field type is enum and all the instances are annotated with @NimnChar

Attension

• There is a possibility when you add a field into the class but miss to specify into the @Nimn(sequence), IDE plugin can warn you

Deserializing

Using constructors or factory methods

By default nimn4j use default constructor to create instance. Instead, you can annotate a factory methos or a constructor for the same using @NimnCreator.

What if a class is singleton, or it's object need to be taken from the pool? polymorphic types
