scanRow

protected void scanRow(String key,
                       String keyInSource,
                       com.couchbase.client.java.document.json.JsonValue value,

                       CouchbaseMetadataProcessor.Dimension dimension)

A dispatcher of scan jsonValue(document, of a segment of document), the jsonValue either can be a JsonObject, or JsonArray, different type dispatch to different scan method.

Parameters:

key - - The attribute name in document, which mapped with value

value - - JsonObject/JsonArray which may contain nested JsonObject/JsonArray

mf -

table -

referenceTableName - - The top table name, used to add foreign key

isNestedType - - Whether the jsonValue are a nested value, or the jsonValue is a segment of document

dimension - - The dimension of nested array, for example, "{"nestedArray": [[["nestedArray"]]]}", the dimension deepest array is 3
