Constructor Details

DateSelector

public DateSelector()

Method Details

toString

public String toString()

Description copied from class: DataType

Basic DataType toString().

Overrides:

toString in class DataType

Returns:

a string describing this object

setMillis

public void setMillis(long millis)

Set the time; for users who prefer to express time in ms since 1970.

Parameters:

millis - the time to compare file's last modified date to, expressed in milliseconds.

getMillis

public long getMillis()

Returns the millisecond value the selector is set for.

Returns:

the millisecond value.

setDatetime

public void setDatetime(String dateTime)

Sets the date. The user must supply it in MM/DD/YYYY HH:MM AM_PM format, unless an alternate pattern is specified via the pattern attribute.

Parameters:

dateTime - a formatted date String.

setCheckdirs

public void setCheckdirs(boolean includeDirs)

Set whether to check dates on directories.

Parameters:

includeDirs - whether to check the timestamp on directories.

setGranularity

public void setGranularity(int granularity)

Sets the number of milliseconds leeway we will give before we consider a file not to have matched a date.

Parameters:

granularity - the number of milliseconds leeway.

setWhen

public void setWhen(DateSelector.TimeComparisons tcmp)

Sets the type of comparison to be done on the file's last modified date.

Parameters:

tcmp - The comparison to perform, an EnumeratedAttribute.

setWhen

public void setWhen(TimeComparison t)

Set the comparison type.

Parameters:

t - TimeComparison object.

setPattern

public void setPattern(String pattern)

Sets the pattern to be used for the SimpleDateFormat.

Parameters:

pattern - the pattern that defines the date format.

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()

This is a consistency check to ensure the selector's required values have been set.

Overrides:

verifySettings in class BaseSelector

isSelected

public boolean isSelected(File basedir,
 String filename,
 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.

Specified by:

isSelected in interface FileSelector

Specified by:

isSelected in class BaseExtendSelector

Parameters:

basedir - the base directory from which the scan is being performed.

filename - is the name of the file to check.

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

Returns:

whether the file is selected.
