US Patent 11288045 Object creation from structured data using indirect constructor invocation

A data-instantiator method handle is configured to instantiate a target class based on a structured data object. One type of data-instantiator method handles is a Structured Data Object Processor method handle (SDOP_mh). The runtime environment invokes a SDOP_mh to create a target object based on a name-index map and an index-value map. The SDOP_mh is adapted, directly or indirectly, from a direct method handle that references a constructor of the target class. In an embodiment, the constructor referenced by the direct method handle is a canonical constructor. In an embodiment, the SDOP_mh is a runtime-computed constant in a runtime constant pool.
