Nested Classes

Modifier and Type	Class	Description
private static final class	DynamicLibrary.DataSymbolMemoryIO	Small MemoryIO wrapper class to keep the library alive
static final class	DynamicLibrary.Symbol
private static final 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
