Example 1 with RadioState

use of org.eclipse.jface.commands.RadioState in project eclipse.platform.ui by eclipse-platform.

the class LegacyActionPersistence method convertActionToCommand.

/**
 * Determine which command to use. This is slightly complicated as actions do
 * not have to have commands, but the new architecture requires it. As such, we
 * will auto-generate a command for the action if the definitionId is missing or
 * points to a command that does not yet exist. All such command identifiers are
 * prefixed with AUTOGENERATED_COMMAND_ID_PREFIX.
 *
 * @param element       The action element from which a command must be
 *                      generated; must not be <code>null</code>.
 * @param primaryId     The primary identifier to use when auto-generating a
 *                      command; must not be <code>null</code>.
 * @param secondaryId   The secondary identifier to use when auto-generating a
 *                      command; must not be <code>null</code>.
 * @param warningsToLog The collection of warnings logged while reading the
 *                      extension point; must not be <code>null</code>.
 * @return the fully-parameterized command; <code>null</code> if an error
 *         occurred.
