Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
private static class	DynamicLibrary.DataSymbolMemoryIO Small MemoryIO wrapper class to keep the library alive
static class	DynamicLibrary.Symbol
private static class	DynamicLibrary.TextSymbolMemoryIO Since the text area of a dynamic library is usually not readable nor writable, wrap the address in a MemoryIO instance that throws an exception on all accesses
