Method Detail

testMap

public void testMap()

testMapWithSchema

public void testMapWithSchema()

Without a schema, leading nulls or empty maps can be ambiguous. With a schema, the meaning is clear.

testMapAsJson

public void testMapAsJson()

testMapArray

public void testMapArray()

testMapArrayWithSchema

public void testMapArrayWithSchema()

With a schema we don't have to infer the type of the map or its members. Instead, we can tolerate extreme ambiguity in both.

testMapArrayWithSchemaInitialNullMember

public void testMapArrayWithSchemaInitialNullMember()

The structure parser feels its way along looking ahead at tokens to guess types. Test the case where the member is an array containing null (so the parser does not know the type). Given a schema, we know it is a map.

testObjectToScalar

public void testObjectToScalar()

testObjectToArray

public void testObjectToArray()
