public abstract class TreeBasedTask
extends StarTeamTask

TreeBasedTask.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).

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

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

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()
