Class Summary

Class	Description
BaseFieldFactory	Base field factor class which handles the common tasks for building column writers and JSON listeners.
BaseJsonLoaderTest
BaseJsonLoaderTest.JsonLoaderFixture
EmptyArrayFieldParser	Represents a run of empty arrays for which we have no type information.
FieldDefn	Describes a new field within an object.
InferredFieldFactory	Create Drill field listeners based on the observed look-ahead tokens in JSON.
JsonLoaderImpl	Revised JSON loader that is based on the ResultSetLoader abstraction.
JsonLoaderImpl.JsonLoaderBuilder
JsonLoaderOptions	Extends the JsonStructureOptions class, which provides JSON syntactic options, with a number of semantic options enforced at the JSON loader level.
NullFieldParser	Parser for a field that contains only nulls.
ProvidedFieldFactory	Create a Drill field listener based on a provided schema.
SimpleArrayListener	Base class for scalar and object arrays.
SimpleArrayListener.ListArrayListener
SimpleArrayListener.StructureArrayListener
TestBasics
TestExtendedArrays
TestExtendedTypes
TestExtendedWithSchema	Test extended types with a schema.
TestMessageParser
TestObjects
TestRepeatedList	Tests repeated lists to form a 2D or 3D array of various data types.
TestScalarArrays	Test scalar arrays.
TestScalars	Tests JSON scalar handling.
TestUnknowns	Tests the ability of the JSON reader to "wait out" a set of leading null or empty array values to wait until an actual value appears before deciding on the column type.
TestVariant
TupleParser	Accepts { name : value ...
