Annotation Type View

@Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface View

A contract method marked as View may access values stored in the persistent contract storage variables, but may not *modify* those values. Essentially you are only *reading* the blockchain state, and not modifying it. Because of this View methods do not require a transaction and consume zero gas. A View method may not also be marked as Payable. Note that in the context of a View method the values in the msg variable are meaningless because this is no actual transaction being made.
