public class ParameterName
extends java.lang.Object

A ParameterName object can represent any parameter name used in Dynamo. Use this class when building your own droplets to create unique parameter names. The parameter names will then be stored in a global hashtable keyed by strings. Using this class allows the parameters of a droplet to be publicly available (for example, to the Workbench) as well as enforcing good coding standards whereby the parameter name string only appears once in the java code.

To get the unique ParameterName for a given String call the static getParameterName() method. This method will look the given string up in the hashtable of parameter names and either return the value or create a new one with the string that was passed in. For example, you might have the following code :

public final static ParameterName EMPTY = ParameterName.getParamterName("empty");

Then, every time you wish to reference that parameter name, you would reference EMPTY as in the following piece of code :

request.serviceLocalParameter(EMPTY, request, response);

Parameters:

pName - the name/string to look up or create.

getName
