Method Summary

Modifier and Type	Method and Description
boolean	isSelected(InstallData idata, File basedir, String filename, File file) The heart of the matter.
void	setCasesensitive(boolean casesensitive) Whether to ignore case when checking filenames.
void	setName(String pattern) The name of the file, or the pattern for the name, that should be used for selection.
void	setNegate(boolean negated) You can optionally reverse the selection of this selector, thereby emulating an <exclude> tag, by setting the attribute negate to true.
void	setParameters(Parameter[] parameters) When using this as a custom selector, this method will be called.

FilenameSelector

public FilenameSelector()

Creates a new FilenameSelector instance.

Method Detail

toString

public String toString()

Overrides:

toString in class Object

Returns:

a string describing this object

setName

public void setName(String pattern)

The name of the file, or the pattern for the name, that should be used for selection.

Parameters:

pattern - the file pattern that any filename must match against in order to be selected.

setCasesensitive

public void setCasesensitive(boolean casesensitive)

Whether to ignore case when checking filenames.

Parameters:

casesensitive - whether to pay attention to case sensitivity

setNegate

public void setNegate(boolean negated)

You can optionally reverse the selection of this selector, thereby emulating an <exclude> tag, by setting the attribute negate to true. This is identical to surrounding the selector with <not></not>.

Parameters:

negated - whether to negate this selection

setParameters

public void setParameters(Parameter[] parameters)

When using this as a custom selector, this method will be called. It translates each parameter into the appropriate setXXX() call.

Specified by:

setParameters in interface Parameterizable

Overrides:

setParameters in class BaseExtendSelector

Parameters:

parameters - the complete set of parameters for this selector

verifySettings

public void verifySettings()

Checks to make sure all settings are kosher. In this case, it means that the name attribute has been set.

Overrides:

verifySettings in class BaseSelector

isSelected

public boolean isSelected(InstallData idata,
                          File basedir,
                          String filename,
                          File file)
                   throws Exception

The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset. Most of the work for this selector is offloaded into SelectorUtils, a static class that provides the same services for both FilenameSelector and DirectoryScanner.

Specified by:

isSelected in interface FileSelector

Specified by:

isSelected in class BaseExtendSelector

Parameters:

basedir - the base directory the scan is being done from

filename - is the name of the file to check

file - is a java.io.File object the selector can use

Returns:

whether the file should be selected or not

Throws:

Exception - if the selector was not configured correctly
