isJsonType back to summary

isJsonType	back to summary
public default boolean isJsonType(final Type type) Check whether provided `Type` is JSON type. JSON type is any class that implements `jakarta.json.JsonValue` interface. Default implementation always returns `false`, because `jakarta.json.JsonValue` interface is not supported in core module without extensions. Parameters type:Type tyoe to be checked Returns:boolean value of `true` when provide type implements `jakarta.json.JsonValue` interface or `false` otherwose

public default boolean isJsonType(final Type type)

Check whether provided Type is JSON type. JSON type is any class that implements jakarta.json.JsonValue interface. Default implementation always returns false, because jakarta.json.JsonValue interface is not supported in core module without extensions.

Parameters

type:Type: tyoe to be checked

Returns:boolean

value of true when provide type implements jakarta.json.JsonValue interface or false otherwose
