摘要：Instrumenting a computer program to provide instrumented byte code includesexamining the byte code, selecting portions of the byte code for instrumentation, andinstrumenting the portions to provide instrumented byte code. Selecting the portionsmay include choosing portions of the byte code corresponding to method entry, methodexit, a throw, a method call, or a new line number. Instrumenting a portion of the bytecode corresponding to a method call may include instrumenting a local line number ofsource code corresponding to the byte code being instrumented. Instrumenting theportions may include adding calls to instrumentation runtime functions that pass

parameters indicative of the portions being instrumented. At least one of the parametersthat is passed may include a line number of the source code corresponding to theportion being instrumented or a thispointer for the method corresponding to theportion being instrumented. Data from instrumentation may be passed via a messagestream that is viewed as the data is being generated and/or stored.
