## Method Summary

Modifier and Type
Method
Description
`void`
`addConfigElement(ConfigElement config)`
Add a configuration element to this one.
`Object`
`clone()`
`boolean`
`expectsModification()`
If your config element expects to be modified in the process of a test run, and you want those modifications to carry over from sample to sample (as in a cookie manager - you want to save all cookies that get set throughout the test), then return true for this method.

## Method Details

### addConfigElement

void addConfigElement(ConfigElement config)
Add a configuration element to this one. This allows config elements to combine and give a "layered" effect. For example, HTTPConfigElements have properties for domain, path, method, and parameters. If element A has everything filled in, but null for domain, and element B is added, which has only domain filled in, then after adding B to A, A will have the domain from B. If A already had a domain, then the correct behavior is for A to ignore the addition of element B.

Parameters:
  `config` - the element to be added to this ConfigElement

### expectsModification

boolean expectsModification()
If your config element expects to be modified in the process of a test run, and you want those modifications to carry over from sample to sample (as in a cookie manager - you want to save all cookies that get set throughout the test), then return true for this method. Your config element will not be cloned for each sample. If your config elements are more static in nature, return false. If in doubt, return false.

Returns:
  true if the element expects to be modified over the course of a test run

### clone

Object clone()
