All Implemented Interfaces:
```
public class JsonField<T extends Object>

                    
```
A class representing a serializable JSON field.
It can either be a KnownValue value of type T, matching the type the SDK expects, or an arbitrary JSON value that bypasses the type system (via JsonValue).

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public interface`	`JsonField.Visitor`	An interface that defines how to map each possible state of a `JsonField<T>` to a value of type R.
`public final class`	`JsonField.IsMissing`	This class is a Jackson filter that can be used to exclude missing properties from objects. This filter should not be used directly and should instead use the @ExcludeMissing annotation.
`public final class`	`JsonField.Deserializer`

Method Summary

Modifier and Type	Method	Description
`final Boolean`	`isMissing()`	Returns whether this field is missing, which means it will be omitted from the serialized JSON entirely.
`final Boolean`	`isNull()`	Whether this field is explicitly set to `null`.
`final Optional<T>`	`asKnown()`	Returns an Optional containing this field's "known" value, meaning it matches the type the SDK expects, or an empty Optional if this field contains an arbitrary JsonValue.
`final Optional<JsonValue>`	`asUnknown()`	Returns an Optional containing this field's arbitrary JsonValue, meaning it mismatches the type the SDK expects, or an empty Optional if this field contains a "known" value.
`final Optional<Boolean>`	`asBoolean()`	Returns an Optional containing this field's boolean value, or an empty Optional if it doesn't contain a boolean.
`final Optional<Number>`	`asNumber()`	Returns an Optional containing this field's numerical value, or an empty Optional if it doesn't contain a number.
`final Optional<String>`	`asString()`	Returns an Optional containing this field's string value, or an empty Optional if it doesn't contain a string.
`final String`	`asStringOrThrow()`
`final Optional<List<JsonValue>>`	`asArray()`	Returns an Optional containing this field's list value, or an empty Optional if it doesn't contain a list.
`final Optional<Map<String, JsonValue>>`	`asObject()`	Returns an Optional containing this field's map value, or an empty Optional if it doesn't contain a map.
`final <R extends Any> R`	`accept(JsonField.Visitor<T, R> visitor)`	Returns the result of calling the visitor method corresponding to this field's state.
`final static <T extends Any> JsonField<T>`	`of(T value)`	Returns a JsonField containing the given "known" value.
`final static <T extends Any> JsonField<T>`	`ofNullable(T value)`	Returns a JsonField containing the given "known" value, or JsonNull if value is null.

  - isMissing
```
 final Boolean isMissing()
```
    Returns whether this field is missing, which means it will be omitted from the serialized JSON entirely.
  - isNull
```
 final Boolean isNull()
```
    Whether this field is explicitly set to null.
  - asKnown
```
 final Optional<T> asKnown()
```
    Returns an Optional containing this field's "known" value, meaning it matches the type the SDK expects, or an empty Optional if this field contains an arbitrary JsonValue.
    This is the opposite of asUnknown.
  - asUnknown
```
 final Optional<JsonValue> asUnknown()
```
    Returns an Optional containing this field's arbitrary JsonValue, meaning it mismatches the type the SDK expects, or an empty Optional if this field contains a "known" value.
    This is the opposite of asKnown.
  - asBoolean
```
 final Optional<Boolean> asBoolean()
```
    Returns an Optional containing this field's boolean value, or an empty Optional if it doesn't contain a boolean.
    This method checks for both a KnownValue containing a boolean and for JsonBoolean.
  - asNumber
```
 final Optional<Number> asNumber()
```
    Returns an Optional containing this field's numerical value, or an empty Optional if it doesn't contain a number.
    This method checks for both a KnownValue containing a number and for JsonNumber.
  - asString
```
 final Optional<String> asString()
```
    Returns an Optional containing this field's string value, or an empty Optional if it doesn't contain a string.
    This method checks for both a KnownValue containing a string and for JsonString.
  - asStringOrThrow
```
 final String asStringOrThrow()
```
  - asArray
```
 final Optional<List<JsonValue>> asArray()
```
    Returns an Optional containing this field's list value, or an empty Optional if it doesn't contain a list.
    This method checks for both a KnownValue containing a list and for JsonArray.
  - asObject
```
 final Optional<Map<String, JsonValue>> asObject()
```
    Returns an Optional containing this field's map value, or an empty Optional if it doesn't contain a map.
    This method checks for both a KnownValue containing a map and for JsonObject.
  - accept
```
 final <R extends Any> R accept(JsonField.Visitor<T, R> visitor)
```
    Returns the result of calling the visitor method corresponding to this field's state.
  - of
```
 final static <T extends Any> JsonField<T> of(T value)
```
    Returns a JsonField containing the given "known" value.
  - ofNullable
```
 final static <T extends Any> JsonField<T> ofNullable(T value)
```
    Returns a JsonField containing the given "known" value, or JsonNull if value is null.
