| In addition to <a href="DocScope.html" title="Article in Oomph Setup Documentation">scopes</a> there are several other important structural elements for organizing and maintaining setup information. |
| </p> |
| |
| <h2><a name="DocIndex"></a>1 Index</h2> |
| <p> |
| An <a href="../../javadoc/org/eclipse/oomph/setup/Index.html" title="Interface in org.eclipse.oomph.setup"><code>index</code></a> is a <a href="../../javadoc/org/eclipse/oomph/setup/Index.html#getProductCatalogs()" title="Method in org.eclipse.oomph.setup.Index"><code>container</code></a> for <a href="DocScope.html#DocProductCatalog" title="Chapter in Oomph Setup Documentation">product catalogs</a> |
| as well as a <a href="../../javadoc/org/eclipse/oomph/setup/Index.html#getProjectCatalogs()" title="Method in org.eclipse.oomph.setup.Index"><code>container</code></a> for <a href="DocScope.html#DocProductCatalog" title="Chapter in Oomph Setup Documentation">project catalogs</a>. |
| It also <a href="../../javadoc/org/eclipse/oomph/setup/Index.html#getDiscoverablePackages()" title="Method in org.eclipse.oomph.setup.Index"><code>provides access</code></a> to all task models. |
| All available <a href="DocScope.html#DocProduct" title="Chapter in Oomph Setup Documentation">products</a> and <a href="DocScope.html#DocProject" title="Chapter in Oomph Setup Documentation">projects</a> are reachable from the index. |
| All the <a href="../user/wizard/index.html" title="Category in Oomph Setup Documentation">setup wizards</a> are driven by this information. |
| The index also <a href="../../javadoc/org/eclipse/oomph/setup/Index.html#getDiscoverablePackages()" title="Method in org.eclipse.oomph.setup.Index"><code>maintains references</code></a> to dynamic Ecore models that provide additional <a href="DocTask.html" title="Article in Oomph Setup Documentation">task</a> implementations. |
| It is stored in the <a href="DocSetupResource.html#DocInstallationResource" title="Chapter in Oomph Setup Documentation">installation resource</a>. |
| </p> |
| |
| <h2><a name="DocLocationCatalog"></a>2 Location Catalog</h2> |
| <p> |
| A <a href="../../javadoc/org/eclipse/oomph/setup/LocationCatalog.html" title="Interface in org.eclipse.oomph.setup"><code>location catalog</code></a> maintains an index of all <a href="DocScope.html#DocInstallation" title="Chapter in Oomph Setup Documentation">installations</a> and <a href="DocScope.html#DocWorkspace" title="Chapter in Oomph Setup Documentation">workspaces</a> |
| installed and provisioned by Oomph, |
| including any installation where Oomph is installed, |
| and any workspace opened by any installation with Oomph installed. |
| It maintains a two-way map, |
| i.e., for each installation, the workspaces it has opened are <a href="../../javadoc/org/eclipse/oomph/setup/LocationCatalog.html#getInstallations()" title="Method in org.eclipse.oomph.setup.LocationCatalog"><code>recorded</code></a> |
| and for each workspace, the installations that have opened it are <a href="../../javadoc/org/eclipse/oomph/setup/LocationCatalog.html#getWorkspaces()" title="Method in org.eclipse.oomph.setup.LocationCatalog"><code>recorded</code></a>. |
| Each time a product with Oomph installed is started, |
| its installation-workspace pair is added to the maps. |
| The installation-to-workspace map is ordered, |
| so the most recently installed or started installation is moved to the front |
| and its workspace is moved to the front of the list associated with that installation. |
| Similarly, the workspace-to-installation map is ordered, |
| so the most recently provisioned or opened workspace is moved to the front |
| and the installation that opened it is moved to the front of the list associated with that workspace. |
| It is stored in the <a href="DocSetupResource.html#DocLocationResource" title="Chapter in Oomph Setup Documentation">location resource</a>. |
| </p> |
| |
| <h2><a name="DocCatalogSelection"></a>3 Catalog Selection</h2> |
| <p> |
| A <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html" title="Interface in org.eclipse.oomph.setup"><code>catalog selection</code></a> maintains an installation and provisioning history for the <a href="../user/wizard/index.html" title="Category in Oomph Setup Documentation">setup wizards</a>. |
| It maintains the following: |
| <ul> |
| <li> |
| The <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html#getProductCatalogs()" title="Method in org.eclipse.oomph.setup.CatalogSelection"><code>selected subset</code></a> of the <a href="DocInfrastructure.html#DocIndex" title="Chapter in Oomph Setup Documentation">index</a>'s available <a href="DocScope.html#DocProductCatalog" title="Chapter in Oomph Setup Documentation">product catalogs</a> displayed in the <a href="../user/wizard/DocProductPage.html" title="Article in Oomph Setup Documentation">product page</a>. |
| </li> |
| The <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html#getDefaultProductVersions()" title="Method in org.eclipse.oomph.setup.CatalogSelection"><code>most recently selected</code></a> <a href="DocScope.html#DocVersion" title="Chapter in Oomph Setup Documentation">product version</a> of each <a href="DocScope.html#DocProduct" title="Chapter in Oomph Setup Documentation">product</a> displayed in the <a href="../user/wizard/DocProductPage.html" title="Article in Oomph Setup Documentation">product product page</a>. |
| </li> |
| <li> |
| The <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html#getProjectCatalogs()" title="Method in org.eclipse.oomph.setup.CatalogSelection"><code>selected subset</code></a> of the <a href="DocInfrastructure.html#DocIndex" title="Chapter in Oomph Setup Documentation">index</a>'s available <a href="DocScope.html#DocProjectCatalog" title="Chapter in Oomph Setup Documentation">project catalogs</a> displayed in the <a href="../user/wizard/DocProjectPage.html" title="Article in Oomph Setup Documentation">project page</a>. |
| </li> |
| The <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html#getDefaultStreams()" title="Method in org.eclipse.oomph.setup.CatalogSelection"><code>most recently selected</code></a> <a href="DocScope.html#DocStream" title="Chapter in Oomph Setup Documentation">stream</a> of each <a href="DocScope.html#DocProject" title="Chapter in Oomph Setup Documentation">project</a> ever chosen in the <a href="../user/wizard/DocProjectPage.html" title="Article in Oomph Setup Documentation">project page</a>. |
| </li> |
| </li> |
| The <a href="../../javadoc/org/eclipse/oomph/setup/CatalogSelection.html#getSelectedStreams()" title="Method in org.eclipse.oomph.setup.CatalogSelection"><code>most recently selected</code></a> <a href="DocScope.html#DocStream" title="Chapter in Oomph Setup Documentation">streams</a> chosen by the <a href="../user/wizard/DocProjectPage.html" title="Article in Oomph Setup Documentation">project page</a>. |
| </li> |
| </ul> |
| In other words, it maintains a persistent initial state for all the <a href="../user/wizard/index.html" title="Category in Oomph Setup Documentation">setup wizards</a>. |
| It is stored in the <a href="DocSetupResource.html#DocCatalogSelectionResource" title="Chapter in Oomph Setup Documentation">catalog selection resource</a>. |
