package org.apache.commons.attributes;

 * Thrown when attempting to get attributes for a parameter of a constructor or method
 * and the parameter index is out of bounds.
 * <p>Note: for performance reasons, this exception is only thrown when the 
 * Commons Attribute runtime can quickly determine that the index is out of bounds.
 * Therefore, you may sometimes be able to pass an invalid index and not receive this
 * exception. For example, if the runtime knows that the method or constructor has
 * no attributes at all, an empty collection / null or false (as appropriate) will be 
 * returned instead. Put simply, <i>don't use this exception to test how many parameters
 * a method or constructor has.
 * @since 2.2
public class ParameterIndexOutOfBoundsException extends IndexOutOfBoundsException {
     * Create a new ParameterIndexOutOfBoundsException.
     * @param methodOrConstructorName the name of the method or constructor whose parameter
     *                                the client tried to get attributes for.
     * @param index the index supplied by the client.
     * @param maxIndex the maximum + 1 parameter index allowed. For example, if a method takes
     *                 two parameters, the maximum allowed index is 1, and this parameter should
     *                 be set to 2. There is no minIndex parameter - it is assumed to be 0.
    public ParameterIndexOutOfBoundsException (String methodOrConstructorName, int index, int maxIndex) {
