use of com.mucommander.ui.dialog.file.FileCollisionRenameDialog in project mucommander by mucommander.

the class AbstractCopyJob method checkForCollision.

/**
 * Checks if there is a file collision (file exists in the destination).
 * If there is no collision this method returns destFile.
 * If there is a collision this method returns: <ul>
 *  <li>null if a user cancelled the transfer
 *  <li>null if a user skipped the file
 *  <li>destFile if a user resumed the transfer (and sets append flag)
 *  <li>destFile if a user has chosen to overwrite the file
 *  <li>new file if a user renamed the file
 *  </ul>
 * @param file a source file
 * @param destFolder a destination folder
 * @param destFile a destination file
 * @param allowCaseVariation if true,
 * @return destFile the new destination file
