Constructor Summary

DateSelector()


Method Summary

long getMillis()
          Returns the millisecond value the selector is set for.

boolean isSelected(java.io.File basedir, java.lang.String filename, java.io.File file)
          The heart of the matter.

void setCheckdirs(boolean includeDirs)
          Should we be checking dates on directories?

void setDatetime(java.lang.String dateTime)
          Sets the date.

void setGranularity(int granularity)
          Sets the number of milliseconds leeway we will give before we consider a file not to have matched a date.

void setMillis(long millis)
          For users that prefer to express time in milliseconds since 1970

void setParameters(Parameter[] parameters)
          When using this as a custom selector, this method will be called.

void setWhen(DateSelector.TimeComparisons cmp)
          Sets the type of comparison to be done on the file's last modified date.

java.lang.String toString()


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

Constructor Detail

DateSelector


public DateSelector()

Method Detail

toString


public java.lang.String toString()

Overrides:: toString in class java.lang.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()

Returns the millisecond value the selector is set for.

setDatetime


public void setDatetime(java.lang.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.

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

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(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.

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
