REPRESENTATION AND CONVERSION OF DYNAMICALLY-TYPED ARRAYS

摘要

Representation of an array in dynamically-typed program code at runtime is provided. Program code is accessed at runtime. An instruction for adding, updating or deleting one or more elements for an array is detected within the code. The array is associated with a first kind of element comprising a first representation and packing format. A second kind of element is determined based on at least one of the instruction or the one or more elements, the second kind of element comprising at least one of a second representation or packing format. A determination is made that the first and second kind of elements are not consistent, based on an inconsistency between the first and second representation formats or packing formats. The array is converted so that the first and second kind of elements are consistent. One or more array elements are added, updated or deleted based on the instruction.
