Abstract Value Members
- abstract def extension[T <: Extension](ext: ExtensionId[T]): T
Returns the payload that is associated with the provided extension throws an IllegalStateException if it is not registered.
Returns the payload that is associated with the provided extension throws an IllegalStateException if it is not registered. This method can potentially block, waiting for the initialization of the payload, if is in the process of registration from another Thread of execution
- abstract def hasExtension(ext: ExtensionId[_ <: Extension]): Boolean
Returns whether the specified extension is already registered, this method can potentially block, waiting for the initialization of the payload, if is in the process of registration from another Thread of execution
- abstract def registerExtension[T <: Extension](ext: ExtensionId[T]): T
Registers the provided extension and creates its payload, if this extension isn't already registered This method has putIfAbsent-semantics, this method can potentially block, waiting for the initialization of the payload, if is in the process of registration from another Thread of execution

(Since version 2.12.16) Use
formatString.format(value)instead ofvalue.formatted(formatString), or use thef""string interpolator. In Java 15 and later,formattedresolves to the new method in String which has reversed parameters.
