Example 56 with LightVirtualFile

use of com.intellij.testFramework.LightVirtualFile in project intellij-community by JetBrains.

the class CodeFormatterFacade method wrapLongLinesIfNecessary.

/**
   * Inspects all lines of the given document and wraps all of them that exceed {@link CodeStyleSettings#getRightMargin(Language)}
   * right margin}.
   * <p/>
   * I.e. the algorithm is to do the following for every line:
   * <p/>
   * <pre>
   * <ol>
   *   <li>
   *      Check if the line exceeds {@link CodeStyleSettings#getRightMargin(Language)}  right margin}. Go to the next line in the case of
   *      negative answer;
   *   </li>
   *   <li>Determine line wrap position; </li>
   *   <li>
   *      Perform 'smart wrap', i.e. not only wrap the line but insert additional characters over than line feed if necessary.
   *      For example consider that we wrap a single-line comment - we need to insert comment symbols on a start of the wrapped
   *      part as well. Generally, we get the same behavior as during pressing 'Enter' at wrap position during editing document;
   *   </li>
   * </ol>
   </pre>
   *
   * @param file        file that holds parsed document tree
   * @param document    target document
   * @param startOffset start offset of the first line to check for wrapping (inclusive)
   * @param endOffset   end offset of the first line to check for wrapping (exclusive)
