public abstract class TreeBasedTask
extends StarTeamTask

FileBasedTask.java This abstract class is the base for any tasks that are tree-based, that is, for tasks which iterate over a tree of folders in StarTeam which is reflected in a tree of folder the local machine. This class provides the tree-iteration functionality. Derived classes will implement their specific task functionality by the visitor pattern, specifically by implementing the method `visit(Folder rootStarteamFolder, java.io.File rootLocalFolder)` Created: Sat Dec 15 16:55:19 2001

Field Detail

### DEFAULT_INCLUDESETTING

    public static final java.lang.String DEFAULT_INCLUDESETTING

  This constant sets the filter to include all files. This default has the same result as `setIncludes("*")`.

  See Also:
    `getIncludes()`, `setIncludes(String includes)`, Constant Field Values

### DEFAULT_EXCLUDESETTING

    public static final java.lang.String DEFAULT_EXCLUDESETTING

  This disables the exclude filter by default. In other words, no files are excluded. This setting is equivalent to `setExcludes(null)`.

  See Also:
    `getExcludes()`, `setExcludes(String excludes)`

Constructor Detail

### TreeBasedTask

    public TreeBasedTask()

Method Detail

### setRootStarteamFolder

    public void setRootStarteamFolder(java.lang.String rootStarteamFolder)

  Set the root of the subtree in the StarTeam repository from which to work; optional. Defaults to the root folder of the view ('/').

  Parameters:
    `rootStarteamFolder` - the root folder

### getRootStarteamFolder

    public java.lang.String getRootStarteamFolder()

  returns the root folder in the Starteam repository used for this operation

  Returns:
    the root folder in use

### setRootLocalFolder

    public void setRootLocalFolder(java.lang.String rootLocalFolder)

  Set the local folder that will be the root of the tree to which files are checked out; optional. If this is not supplied, then the StarTeam "default folder" associated with `rootstarteamfolder` is used.

  Parameters:
    `rootLocalFolder` - the local folder that will mirror this.rootStarteamFolder
  See Also:
    `rootLocalFolder`

### getRootLocalFolder

    public java.lang.String getRootLocalFolder()

  Returns the local folder specified by the user, corresponding to the starteam folder for this operation or null if not specified.

  Returns:
    the local folder that mirrors this.rootStarteamFolder
  See Also:
    `rootLocalFolder`

### setIncludes

    public void setIncludes(java.lang.String includes)

  Declare files to include using standard `includes` patterns; optional.

  Parameters:
    `includes` - A string of filter patterns to include. Separate the patterns by spaces.
  See Also:
    `getIncludes()`, `setExcludes(String excludes)`, `getExcludes()`

### getIncludes

    public java.lang.String getIncludes()

  Gets the patterns from the include filter. Rather that duplicate the details of AntStarTeamCheckOut's filtering here, refer to these links:

  Returns:
    A string of filter patterns separated by spaces.
  See Also:
    `setIncludes(String includes)`, `setExcludes(String excludes)`, `getExcludes()`

### logIncludes

    protected void logIncludes()

  if excludes have been specified, emit the list to the log

### setExcludes

    public void setExcludes(java.lang.String excludes)

  Declare files to exclude using standard `excludes` patterns; optional. When filtering files, AntStarTeamCheckOut uses an unmodified version of `DirectoryScanner`'s `match` method, so here are the patterns straight from the Ant source code:
  Matches a string against a pattern. The pattern contains two special characters:
  '*' which means zero or more characters,
  '?' which means one and only one character.
  For example, if you want to check out all files except .XML and .HTML files, you would put the following line in your program: `setExcludes("*.XML,*.HTML");` Finally, note that filters have no effect on the directories that are scanned; you could not skip over all files in directories whose names begin with "project," for instance.
  Treatment of overlapping inlcudes and excludes: To give a simplistic example suppose that you set your include filter to "*.htm *.html" and your exclude filter to "index.*". What happens to index.html? AntStarTeamCheckOut will not check out index.html, as it matches an exclude filter ("index.*"), even though it matches the include filter, as well.
  Please also read the following sections before using filters:

  Parameters:
    `excludes` - A string of filter patterns to exclude. Separate the patterns by spaces.
  See Also:
    `setIncludes(String includes)`, `getIncludes()`, `getExcludes()`

### getExcludes

    public java.lang.String getExcludes()

  Gets the patterns from the exclude filter. Rather that duplicate the details of AntStarTeanCheckOut's filtering here, refer to these links:

  Returns:
    A string of filter patterns separated by spaces.
  See Also:
    `setExcludes(String excludes)`, `setIncludes(String includes)`, `getIncludes()`

### logExcludes

    protected void logExcludes()

    public final void execute()
                       throws BuildException

                      throws BuildException

  Helper method calls on the StarTeam API to retrieve an ID number for the specified view, corresponding to this.label.

  Parameters:
    `v` - the `View` in which to search for `this.label`
  Returns:
    the ID number corresponding to `this.label` or -1 if no label was provided.
  Throws:
    `BuildException` - if `this.label` does not correspond to any label in the supplied view

### getIDofLabelInUse

    protected int getIDofLabelInUse()

### visit

    protected abstract void visit(com.starbase.starteam.Folder rootStarteamFolder,

                           throws BuildException

  Derived classes must override this class to define actual processing to be performed on each folder in the tree defined for the task

  Parameters:
    `rootStarteamFolder` - the StarTeam folderto be visited
    `rootLocalFolder` - the local mapping of rootStarteamFolder
  Throws:
    `BuildException`

### testPreconditions

    protected abstract void testPreconditions()
                                       throws BuildException

  Derived classes must override this method to define tests for any preconditons required by the task. This method is called at the beginning of the execute() method.

  Throws:
    `BuildException` - throw if any fatal error exists in the parameters supplied. If there is a non-fatal condition, just writing to the log may be appropriate.
  See Also:
    `execute()`

### getFullRepositoryPath

    public static java.lang.String getFullRepositoryPath(com.starbase.starteam.File remotefile)

  Return the full repository path name of a file. Surprisingly there's no method in com.starbase.starteam.File to provide this.

  Parameters:
    `remotefile` - the Star Team file whose path is to be returned
  Returns:
    the full repository path name of a file.
