Constructor Detail

FilenameSelector


public FilenameSelector()
Method Detail

toString


public java.lang.String toString()
Overrides:
toString in class java.lang.Object

setName


public void setName(java.lang.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(java.io.File basedir,
                          java.lang.String filename,
                          java.io.File file)
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
