  1. POSelecting correct Enum
    text
    copied!<p>I have a number of Enums each of which contain the names of attributes to be tested. The problem I have is how to select the relevant enum for the object. How can I define just a Enum variable which use throughout my code which can be set through an initalise method.</p> <p>EDIT:</p> <p>Sorry for the delayed reponse. I had to step away from the desk</p> <p>It very well be bad design. I have a few enums as follows:</p> <pre><code>public enum AccountGrpEnum { Account("Account"), AccountType("AccountType"), AcctIDSource("AcctIDSource"); private static Set&lt;String&gt; grpNames = new HashSet&lt;String&gt;(3) {{ for(AccountGrpEnum e : AccountGrpEnum.values()) { add(e.toString()); } }}; public static boolean contains(String name) { return grpNames.contains(name); } private String name; private AccountGrpEnum(String name) { this.name = name; } public String toString() { return this.name; } } </code></pre> <p>Another <code>Enum</code>:</p> <pre><code>public enum BlockManValEnum { avgPx("avgPx"), quantity("quantity"), securityIDSource("securityIDSource"), securityID("securityID"), blockStatus("blockStatus"), side("side"); private static Set&lt;String&gt; names = new HashSet&lt;String&gt;(9) {{ for(BlockManValEnum e : BlockManValEnum.values()) { add(e.toString()); } }}; public static boolean contains(String name) { return names.contains(name); } private String name; private BlockManValEnum(String name) { this.name = name; } public String toString() { return this.name; } } </code></pre> <p>Within my code I am checking the fields of an incoming object to see they are contained within the Enum. As follows:</p> <pre><code>if (BlockManValEnum.contains(fields[i].getName())) </code></pre> <p>however I would like it to be along the lines of </p> <pre><code>if (variableEnum.contains(fields[i].getName())) </code></pre> <p>Where <code>variableEnum</code> can be set at runtime.</p> <p>Hope this is clearer guys</p>
