1. object CAPSJsonSerialiser extends JsonSerialiser

   

   Serialises CAPSRecords to a JSON string.

   Serialises CAPSRecords to a JSON string. The format is as follows:

   {
     "columns" : [ "key" ]   // array of columns
     "rows" : [              // array of rows
       {                     // each row is an object
         "key" : "value"     // each cell is a tuple
       }
     ]
   }

   CAPSGraphs are serialized in the following format:

   {
     "nodes" : [ LIST_OF_NODES ]   // array of nodes
     "edges" : [ LIST_OF_EDGES ]   // array of relationships
     "labels": [ "Person", "Book"] // each label present in the graph
     "types": [ "KNOWS", "READS"]  // each relationship type present in the graph
   }

   The format of scalar values follows the format of org.opencypher.okapi.api.value.CypherValue.CypherValue#toString. The format of nodes is as follows:

   "n" : {
     "id" : 0,           // id is an integer
     "labels" : [        // labels is an array of strings
       "A",
       "B"
     ],
     "properties" : {    // properties is an object
       "key" : "value",  // key-value is a tuple
       "foo" : bar
     }
   }

   The format of relationships is as follows:

   "n" : {
     "id" : 0,           // id is an integer
     "source" : 0,       // id of source node
     "target" : 0,       // id of target node
     "type" : "T"        // relationship type is a string
     "properties" : {    // properties is an object
       "key" : "value",  // key-value is a tuple
       "foo" : bar
     }
   }
