Packed data objects

摘要

A computer-implemented process for creating a packed data object, the computer-implemented process comprising providing instrumentation to an enhanced runtime by an enhanced compiler for a computer executable program portion, detecting a special class in the computer executable program portion by the enhanced runtime, creating an internal representation of a packed data object header using the instrumentation, calculating a size of elements for a packed data object associated with the computer executable program portion, determining a type of packed data object using information in the packed data object header, and responsive to a determination that the type of packed data object is an on-heap packed data object, storing the packed data object header and associated packed data object data together for the packed data object in a memory heap.

1. A computer-implemented process for creating a packed data object, the computer-implemented process comprising:
providing instrumentation to an enhanced runtime by an enhanced compiler for a computer executable program portion; detecting a special class in the computer executable program portion by the enhanced runtime; creating an internal representation of a packed data object header using the instrumentation; calculating a size of elements for a packed data object associated with the computer executable program portion; determining a type of packed data object using information in the packed data object header; and responsive to a determination that the type of packed data object is an on-heap packed data object, storing the packed data object header and associated packed data object data together for the packed data object in a memory heap.
