Constructor Detail

DateSelector

public DateSelector()

Creates a new DateSelector instance.

Method Detail

toString

public String toString()

Overrides:

toString in class Object

Returns:

a string describing this object

setMillis

public void setMillis(long millis)

For users that prefer to express time in milliseconds since 1970

Parameters:

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

getMillis

public long getMillis()
               throws Exception

Returns the millisecond value the selector is set for.

Returns:

the millisecond value

Throws:

Exception

setDatetime

public void setDatetime(String dateTime)

Sets the date. The user must supply it in MM/DD/YYYY HH:MM AM_PM format

Parameters:

dateTime - a string in MM/DD/YYYY HH:MM AM_PM format

setCheckdirs

public void setCheckdirs(boolean includeDirs)

Should we be checking 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 milliconds leeway

setWhen

public void setWhen(DateSelector.TimeComparisons cmp)

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

Parameters:

cmp - The comparison to perform, an EnumeratedAttribute

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(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.

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
