Examples of serp.bytecode.BCClass

serp.bytecode.BCClass
The BCClass represents a class object in the bytecode framework, in many ways mirroring the {@link Class} class of Java reflection. The representedclass might be a primitive, array, existing object type, or some new user- defined type. As with most entities in the bytecode framework, the BCClass contains methods to manipulate the low-level state of the class (constant pool indexes, etc), but these can and should be ignored in favor of the available high-level methods.
A BCClass instance is loaded from a {@link Project} and remainsattached to that project for its lifetime. If a BCClass is removed from its project, the result of any further operations on the class are undefined.

Note that if a BCClass represents a primitive or array type, all of the available mutator methods and any methods that access the constant pool will throw {@link UnsupportedOperationException}s.
