\nI recently was working on an application where I needed to verify that certain static constants were defined by a specific class. I have run into similar situations like this before so I decided to write a simple utility which I could reuse.\n<\/p>\n
\nConstantDefinitionUtil is an all static class which provides an API for determining if specific constants have been defined by a class.\n<\/p>\n
\nAdditionally, ConstantDefinitionUtil provides a method for retrieving all static constants which have been defined by a class.\n<\/p>\n
\nThe following example demonstrates how ConstantDefinitionUtil can be utilized to determine if the static constant “X” has been defined by ClassA:\n<\/p>\n
\r\npackage\r\n{\r\n public class ClassA\r\n {\r\n public static const X:int = 1;\r\n public static const Y:int = 2;\r\n public static const Z:int = 3;\r\n }\r\n}\r\n\r\nimport com.ericfeminella.utils.ConstantDefinitionUtil;\r\n\r\ntrace( ConstantDefinitionUtil.isDefinedBy(\"X\",ClassA) ); \/\/true\r\n<\/pre>\nConstantDefinitionUtil.as<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"I recently was working on an application where I needed to verify that certain static constants were defined by a specific class.
