Class Attribute

java.lang.Object

gov.llnl.babel.ast.ASTNode

gov.llnl.babel.ast.Attribute

All Implemented Interfaces:

java.lang.Comparable

public class Attribute
extends ASTNode
implements java.lang.Comparable

General encapsulation of built-in attributes (such as final or abstract) as well as user-defined attributes, including both singletons, or key-value pairs.

Built-in varieties are assumed to have an implicit key with a leading underscore for instance nonblocking, oneway, local are all mutually exclusive values on the key _communication. Use getVisibleKey if you prefer not to be bothered with this implementation detail. User defined varieties such as %attrib{blue} are assigned to keys with the value of null. Note that keys tend to be mutually exclusive... so %attrib{color,color=blue} will cause a compilation error.
