The users of the version control system can branch any branch. Branches are also known as trees, streams or codelines. The originating branch is sometimes called the parent branch, the upstream branch (or simply upstream, especially if the branches are maintained by different organizations or individuals), or the backing stream.
Rebasing is the act of moving changesets to a different branch when using a revision control system or in some systems, by synchronizing a branch with the originating branch by merging all new changes in the latter to the former. For example, Git and Darcs do this (but Darcs extends the concept and calls it "patch commutation").
Upstream development allows other distributions to benefit from it when they pick up the future release or merge recent (or all) upstream patches. [1] Likewise, the original authors (maintaining upstream) can benefit from contributions that originate from custom distributions, if their users send patches upstream.
The runtime overhead of added instrumentation is small (5–20%) and the bytecode instrumentor itself is very fast (mostly limited by file I/O speed). Memory overhead is a few hundred bytes per Java class. EMMA is 100% pure Java, has no external library dependencies, and works in any Java 2 JVM (even 1.2.x).

This sometimes involves an addition of the offset onto the program counter register (unless, in some instruction sets, the branch instruction allows an extra index register). This final address usually points to one of a sequence of unconditional branch instructions, or the instruction immediately beyond them (saving one entry in the table).
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria. It is a form of conditional statement . A multiway branch is often the most efficient method of passing control to one of a set of program labels , especially if an index has been created beforehand from the raw data .
Switch statements function somewhat similarly to the if statement used in programming languages like C/C++, C#, Visual Basic .NET, Java and exist in most high-level imperative programming languages such as Pascal, Ada, C/C++, C#, [1]: 374–375 Visual Basic .NET, Java, [2]: 157–167 and in many other types of language, using such keywords as ...
