model-generator's Introduction

Model-Generator

Generate code for basic models from JSON schema.

Languages

To Do

unit tests for java and groovy before moving on
generate build files in directories

Possible Improvements

Constants / final properties ?
Serialization
Builder methods
hashCode, toString, and equals methods
Parameterized constructor using 'required' on object properties
On a similar note, call parameterized super constructor

Specification

A couple of new properties were added to add more functionality.

extends - extend from other object in another schema
primitive - array: T[] or List ; numbers: Float or float; Integer or int
parseTo - attempt a parse to non-standard JSON schema types (BigDecimal, Long, Byte, etc)
- If parsing fails on a field, it falls back to whatever is specified in type

      }
    },

      "parseTo": "decimal" // attempt parse to BigDecimal for currency handling, falls back to Float if failed
    }
  }
