Class WeaveJsonDataSet

java.lang.Object

weave.beans.WeaveJsonDataSet

public class WeaveJsonDataSet
extends java.lang.Object

Below is an example JSON representation of a WeaveJsonDataSet object. This example illustrates the need to specify keyType by showing that record keys referring to different things can have identical string representations ("25" could refer to a state or a person).

 {
    columns: {
       "22": {"title": "State name", "keyType": "state fips", "dataType": "string"},
       "23": {"title": "Population", "year": "2000", "keyType": "state fips", "dataType": "number"},
       "71": {"title": "Name", "keyType": "person id", "dataType": "string"},
       "72": {"title": "Age", "keyType": "person id", "dataType": "number"},
       "73": {"title": "State", "keyType": "person id", "dataType": "state fips"}
    },
    records: {
       "state fips": {
          "01": {"22": "Alabama", "23": 4452000},
