data-model
==========

Automagically generated test data

This library allows using expanded definition of generated data.
Using JSON format the following information could be defined:
 * field name
 * type (currently supported: identifier, integer, long, date, string, text, array, object, enum)
 * probability - number from 0 to 100, indicating the probability that the 
                 defined field will be present in the generated document (100 
                 means that the field will be present in all the documents, 
                 50 means that about 50% of the documents will contain given field)
 * size (for arrays)
Example of input file: 

{ 
	"data" : {
		"id" : {
			"type" : "identifier"
		},
		"tags" : {
			"type" : "array",
			"subtype" : {
				"type": "integer"
			},
			"size" : 10
		},
		"position" : {
			"type" : "object",
			"fields" : {
				"lon" : {
					"type" : "long"
				},
				"lat" : {
					"type" : "long"
				}
			},
			"probability" : 50
		},
		"created" : {
			"type" : "date"
		},
		"name" : {
			"type" : "string",
			"probability" : 30
		},
		"status" : {
			"type" : "enum",
			"available" : ["OPEN", "WAITING", "RUN", "CLOSED"]
		}
	}
}

Usage:

DataModel model = DataModel.builder().fromJson(DataModelTest.class.getResourceAsStream("/input.json"));




Output depends on producer class used. For example: 

new SolrDataModelProducer().convert(model.getValue());

generates:

<doc>
	<field name="id">30</field>
	<field name="tags">1061831906</field>
	<field name="tags">1823041322</field>
	<field name="tags">1043347384</field>
	<field name="tags">1435798929</field>
	<field name="tags">1863886272</field>
	<field name="tags">614448648</field>
	<field name="tags">899164045</field>
	<field name="tags">293936725</field>
	<field name="tags">1762090246</field>
	<field name="tags">1009759002</field>
	<field name="position.lon">-3400858544594038103</field>
	<field name="position.lat">-3581634897016771756</field>
	<field name="created">2011-05-15T20:57:28</field>
</doc>

For JsonDataModelProducer: 

new JsonDataModelProducer().convert(model.getValue());

output can be:

{
	"id":"3",
	"tags":[1102324772,1639875632,941233980,187315297,99270113,2044803615,1811470888,1093630565,2071000800,2129652106],
	"created":1015062520000
}
