public final Enum LogicalType

Array types of other values.

Binary data such as byte[] and java.nio.ByteBuffer.

java.lang.Boolean, boolean, java.util.concurrent.atomic.AtomicBoolean.

java.util.Collection values (and "Collection-like" for JVM languages and datatype libraries with semantically similar types)

Date/time datatypes such as java.util.Date, java.util.Calendar.

Various java.lang.Enum types.

Basic floating-point numbers types like float, double, and matching wrapper types, java.math.BigDecimal.

Basic integral numbers types like short, int, long and matching wrapper types, java.math.BigInteger.

java.util.Map values (and "Map-like" for JVM languages and datatype libraries with semantically similar types)

Scalar types other than ones listed above: includes types like java.net.URL and java.util.UUID.

Types that are handled by default "set of key/value pairs" serialization, also known as "Beans".

In addition to user-defined types, also includes JDK types like:

• java.lang.Throwable

Purely textual types, java.lang.String and similar (but not types that are generally expressed as Strings in input).

"Non-type", Type used to contained untyped, free-form content: maybe a "Tree" (sometimes called "AST"), or buffer of some kind, or even just nominal type of java.lang.Object

Helper method to use for figuring out logical type from physical type, in cases where caller wants a guess. Note that introspection is not exhaustive and mostly covers basic java.util.Collection, java.util.Map and java.lang.Enum cases; but not more specific types (for example datatype-provided extension types).

Parameters

raw:Class<?>

Type-erased class to classify

defaultIfNotRecognized:LogicalType

if no type recognized, value to return (for example, null)
