| <h3>Description</h3> |
| <p>Adds a component definition to the current project. A component definition is the same as |
| a <a href="typedef.html">typedef</a> except:</p> |
| <ol> |
| <li>that it can only be used in other types or tasks that accept components (by having |
| an <code>add()</code> method).</li> |
| <li>multiple components may have the same name, provided they implement different interfaces.</li> |
| </ol> |
| <p>The purpose of this is to allow internal Apache Ant definitions to be made for tags |
| like <samp>and</samp> or <samp>or</samp>.</p> |
| |
| <h3>Examples</h3> |
| |
| <p>Define two components with the same name <samp>or</samp>; one is a |
| condition (see <a href="conditions.html">conditions</a>) and one is a |
| selector (see <a href="../Types/selectors.html">selectors</a>).</p> |
| <pre> |
| <componentdef name="or" onerror="ignore" |
| classname="com.apache.tools.ant.taskdefs.conditions.Or"/> |
| <componentdef name="or" onerror="ignore" |
| classname="com.apache.tools.ant.types.resources.selectors.Or"/></pre> |
