#Java reflection javadoc code#
An enum is a language construct that is used to define type-safe enumerations which can be used when a fixed set of named values is desired. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled. Consequently, reflective operations have slower performance than their non-reflective counterparts, and should be avoided in sections of code which are called frequently in performance-sensitive applications. Core Java Java Reflection Java Reflection API Guide. Quoting Java's documentation on reflection:īecause reflection involves types that are dynamically resolved, certain Java virtual machine optimizations can not be performed. When the application is on-runtime, the application can modify itself or even see its structure of itself. The classes Reflections and SubTypesScanner are not standard Java classes.
Looking up a class via reflection is, by magnitude, more expensive. Java reflection is a Java feature that allows Java programs to learn or modify themselves.
