All Implemented Interfaces:

java.lang.Cloneable, IrrelevantToPlaybackFilter

public class RelativeTimeFilter
extends Filter

Constructor Detail

RelativeTimeFilter

public RelativeTimeFilter(long relativeOffset)

Create a TimeFilter with the specified cutoff time, and whether the pass condition should be before or after the time.

Parameters:

relativeOffset - long delta time in Java standard milliseconds

Method Detail

getFilterUIName

public java.lang.String getFilterUIName()

Get the class name of a dynamically loadable class for the the GUI for this filter. The name is allowed to have a wildcard '*' in it where a GUI type ("gui" for standard Java or "android" for Android) can be substituted.

Specified by:

getFilterUIName in class Filter

Returns:

String name of GUI class for this filter

isFilterPlaybacks

public boolean isFilterPlaybacks()

Indicate whether packets from log file playbacks should be filtered or not.

Returns:

boolean true if playback messages (no source) will be filtered

setFilterPlaybacks

public void setFilterPlaybacks(boolean filterPlaybacks)

Specify whether packets from log file playbacks should be filtered or not.

Parameters:

filterPlaybacks - boolean true if this filter should apply to playback messages

getRelativeOffsetMsec

public long getRelativeOffsetMsec()

setRelativeOffsetMsec

public void setRelativeOffsetMsec(long relativeOffsetMsec)

isHardReject

public boolean isHardReject()

setHardReject

public void setHardReject(boolean hardReject)

getFilterTypeTagName

public java.lang.String getFilterTypeTagName()

Report a tag name used to look up the labelling for an editor panel for this editor instance in a ResourceBundle of translated names.

Specified by:

getFilterTypeTagName in class Filter

Returns:

String to use in looking up form label for this filter's editor

getFilterHelpTagName

public java.lang.String getFilterHelpTagName()

Report a tag name used to look up JavaHelp for a filter editor.

Specified by:

getFilterHelpTagName in class Filter

Returns:

null because there is no filter specific help

acceptAX25Frame

public int acceptAX25Frame(AX25Frame frame)

Indicate whether the specified message should be displayed or used to determine if a station should be displayed (if recursively called from acceptStation()).

Specified by:

acceptAX25Frame in class Filter

Parameters:

frame - the timestamped AX25 frame record to analyze

Returns:

RESULT_xxx constant indicating if message information should be displayed

acceptMessage

public int acceptMessage(AX25Message msg)

Indicate whether the specified message should be displayed or used to determine if a station should be displayed (if recursively called from acceptStation()).

Specified by:

acceptMessage in class Filter

Parameters:

msg - the APRS Message record to analyze

Returns:

RESULT_xxx constant indicating if message information should be displayed

acceptStation

public int acceptStation(StationState ss)

Indicate whether the specified station should be displayed. The acceptMessage() and acceptAX25Frame() methods may be called to assist in the determination.

Specified by:

acceptStation in class Filter

Parameters:

ss - StationState record to analyze

Returns:

RESULT_xxx constant indicating if station information should be displayed

addFilterChangeListener

public void addFilterChangeListener(FilterChangeListener l)

Register a listener for changes of this Filter.

Specified by:

addFilterChangeListener in class Filter

Parameters:

l - FilterChangeListener to register

removeFilterChangeListener

public void removeFilterChangeListener(FilterChangeListener l)

Deregisters a listener. The listener will no longer be informed of changes to this filter.

Specified by:

removeFilterChangeListener in class Filter

Parameters:

l - FilterChangeListener to deregister

setToPassall

public void setToPassall()

Reset the filter to a configuration that would pass the maximum amount of messages, packets, and stations.

Specified by:

setToPassall in class Filter

fireFilterChange

protected void fireFilterChange()

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement. By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass(). By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Overrides:

clone in class Filter

Returns:

a clone of this instance.

Throws:

java.lang.CloneNotSupportedException - if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.
