Examples of org.dtk.analysis.script.node.ObjectLiteral

org.dtk.analysis.script.node.ObjectLiteral
Extension of the BaseLiteralNode class to support JavaScript object literals. Provides utility method for returning converted element values as a Map class. Provides two public methods, getKeys & getValue, to abstract away the process of traversing node properties to find the list of literal members and their associated values. To ensure we don't have to traverse node for each access, we maintain an internal map of previously discovered values. @author James Thomas
