| <h1> API Use Ant Task </h1> |
| <h2>Purpose</h2> |
| <p>This task runs a complete search of a given baseline to determine a producer-centric report of API usage.</p> |
| <p>The analysis does not include bundles that are not API Tools enabled.</p> |
| |
| <h2>Usage</h2> |
| <h3>Description</h3> |
| <p>The name of the ant task is: <code>apitooling.apiuse</code>. To be used, the jar file <code>apitooling-ant.jar</code> has to be on the ant |
| classpath.</p> |
| <pre> |

| </tr> |
| <tr> |
| <td valign="top">location</td> |
| <td valign="top"> |
| This attribute specifies the location of the current product you want to search for API usage. |
| <br><br> |
| It can be a .zip, .jar, .tgz, .tar.gz file, or a directory that corresponds to a collection of bundles. |
| <br><br> |
| The location is specified using an absolute path.</td> |
| <td align="center" valign="top">Yes</td> |
| </tr> |
| <tr> |
| <td valign="top">scopepattern</td> |
| <td valign="top"> |
| This attribute specifies the regular expression pattern used to build the scope of elements to search for |
| references from in the product location. |
| <br><br> |
| The pattern must be a well-formatted regular expression as |
| defined <a href="http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html">here</a>. |
| </td> |
| <td align="center" valign="top">No</td> |
| </tr> |
| <tr> |
| <td valign="top">referencepattern</td> |
| <td valign="top"> |
| Set the regular expression pattern used to build the scope of elements to search for |
| references to in the product location. |
| <br><br> |
| The pattern must be a well-formatted regular expression as |

| <tr> |
| <td valign="top">report</td> |
| <td valign="top">Set the output location where the reports will be generated. |
| <br><br> |
| Once the task is completed, reports are available in this directory using a hierarchical structure. A sub-folder is created |
| for each component that has another bundle that references it. Each sub-folder contains a file called "[bundlename].xml". Within |
| this folder is another sub-folder (named "[referencing bundle name].xml") for each bundle that references the bundle of the containing folder. |
| Inside the referencing bundle folder is one of three sub-folders (API, PRIVATE or OTHER) which contain type, method or field references of that kind. |
| <br><br> |
| Two other special files are written into the report directory, which are "not_searched.xml" and "no_apidescription.xml" and they contain |
| information about bundles from the baseline that were not search for usage information and those that did not have an .api_description files in them, respectively. |
| <br><br> |
| The location is specified using an absolute path. |
| <br><br> |
| For example: |
| <pre> |
| root |
| | |
| +-- "not_searched.xml" |
| +-- "no_apidescription.xml" |
| +-- bundle name with usage |
| | |
| +--referencing bundle name |

| <td valign="top">apipatterns</td> |
| <td valign="top">A comma separated list of package name patterns (regular expressions) to consider as API packages. |
| <br><br>By default API descriptions are used in the scanned bundles, but this can be used to |
| override or add API packages.</td> |
| <td align="center" valign="top">No</td> |

| <h3>Examples</h3> |
| <pre> |
| <b><font color="#0000ff"><apitooling.apiuse |
| location=<font color="#008000">"/eclipse/eclipse.tar.gz"</font> |
| scopepattern=<font color="#008000">".*"</font> |
| referencepattern=<font color="#008000">"org\.eclipse.*"</font> |
| report=<font color="#008000">"/eclipse/apiuse-both/XML"</font> |
| considerinternal=<font color="#008000">"true"</font> |
| considerapi=<font color="#008000">"true"</font> |
| debug=<font color="#008000">"true"</font> |
| /></font></b> |
| </pre> |
| <p>This will run the task creating <code>*.xml</code> files inside the folder <code>/eclipse/apiuse-both/XML</code>. |
| The task will search all bundles in the product location - defined by the regular expression <code>.*</code> - searching |
| for all references to any bundles whose identifier begins with org.eclipse (defined by the <code>org\.eclipse.*</code> regular expression). |
| <p>If debug is enabled, some debug tracing will show up in the ant console.</p> |
