StackFrame

In previous sections, we iterated through the StackFrame elements, and provided sample code snippets, but did not take the time to examine it more closely. StackFrame is an interface defined inside the StackWalker class. It defines accessors, and a converter that can be used to convert the information to StackTraceElement.

The accessors the interface defines are the following:

• getClassName() will return the binary name of the class of the method represented by the StackFrame.
• getMethodName() will return the name of the method represented by the StackFrame.
• getDeclaringClass() will return the class of the method represented by the StackFrame. If the Option.RETAIN_CLASS_REFERENCE was not used during the creation of the StackWalker instance then the method will throw UnsupportedOperationException.
• getByteCodeIndex() gets the index to the code array containing the execution point of the method represented by the StackFrame. The use of this value can be helpful during bug hunting when looking...
