An apparatus, process, and computer program product to merge types in an object-oriented program is disclosed herein. In one embodiment, a process may include analyzing a method within an object-oriented program to identify merge candidates. These merge candidates may then be recorded in a merge candidate list. The process may further include identifying at least two code paths in the method that merge into a single code path and that operate on different types. The types in these code paths may then be merged to a nearest common superclass listed in the merge candidate list. In selected embodiments, the types may be merged to the java.lang.Object class in the event the merge candidate list is empty.

Type merging technique to reduce class loading during Java verification

A computer implemented method, apparatus, and computer usable program code for processing a class file. The class file is loaded onto a target device. A determination is made whether verification is enabled. Static constraints are checked in response to determining the verification is enabled. A determination is made whether subroutines are present in a set of methods within the class file. The subroutines are in-lined in response to determining that subroutines are present in the set of methods.

Load time in-lining of subroutines

A grenade machine gun or other weapon which employs superelevation of the barrel comprises a barrel unit and an aiming system mounted upon a support. The aiming system is mounted to the weapon and the support by a coupling unit. The aiming system comprises an imaging and display unit for displaying an image of a scene including a target, angle encoders for providing a signal representing displacement of the imaging unit in elevation relative to the support, and a control unit, e.g. a computer, for selecting either of two states for the coupling unit. The first state entrains the imaging unit to move with the barrel. The second state secures the imaging unit to the support and allows the barrel to move relative to both, i.e. during superelevation of the barrel. The coupling unit may comprise a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit. The control unit may comprise a computer for superimposing upon the image an aiming reticle and a rangefinder reticle, the former representing an aiming point of the imaging unit and the latter representing an aiming point of the rangefinder, and may adjust the position of the aiming reticle in dependence upon the elevation signal, and stores coordinates for selected positions. The control computer may offset the displacement signal to displace the aiming reticle relative to the field of view in a direction opposite to the required superelevation angle.
