Constructor Detail

WishRealizationMission

public WishRealizationMission(AIMain aiMain,
                              AIUnit aiUnit,
                              Wish wish)

Creates a mission for the given AIUnit.

Parameters:

aiMain - The main AI-object.

aiUnit - The AIUnit this mission is created for.

wish - The Wish which will be realized by the unit and this mission.

WishRealizationMission

public WishRealizationMission(AIMain aiMain,
                              AIUnit aiUnit,
                              FreeColXMLReader xr)
                       throws javax.xml.stream.XMLStreamException

Creates a new WishRealizationMission from a reader.

Parameters:

aiMain - The main AI-object.

aiUnit - The AIUnit this mission is created for.

xr - The input stream containing the XML.

Throws:

javax.xml.stream.XMLStreamException - if a problem was encountered during parsing.

FreeColObject.readFromXML(net.sf.freecol.common.io.FreeColXMLReader)

Method Detail

getWish

public Wish getWish()

Get the wish handled by this mission.

Returns:

The mission Wish.

invalidMissionReason

public static java.lang.String invalidMissionReason(AIUnit aiUnit,
                                                    Location loc)

Why would this mission be invalid with the given AI unit and location?

Parameters:

aiUnit - The AIUnit to check.

loc - The Location to check.

Returns:

A reason for invalidity, or null if none found.

dispose

public void dispose()

Disposes this mission by removing any references to it.

Overrides:

dispose in class Mission

getBaseTransportPriority

public int getBaseTransportPriority()

Get the base transport priority for the unit performing this mission.

Overrides:

getBaseTransportPriority in class Mission

Returns:

A base transport priority.

getTarget

public Location getTarget()

Gets the target of this mission, if any.

Specified by:

getTarget in class Mission

Returns:

The target of this mission, or null if none.

setTarget

public void setTarget(Location target)

Sets the target of this mission, if any. The actual target is handled in the missions that really have them, this is a helper to make sure the unit is updated.

Specified by:

setTarget in class Mission

Parameters:

target - The new target of this mission, or null if none.

findTarget

public Location findTarget()

Finds a new target for this mission.

Specified by:

findTarget in class Mission

Returns:

A new target for this mission.

invalidReason

public java.lang.String invalidReason()

Why is this mission invalid? Mission subclasses must implement this routine, which probably should start by checking invalidAIUnitReason. A mission can be invalid for a number of subclass-specific reasons. For example: a seek-and-destroy mission could be invalid because of a improved stance towards the targeted player.

Specified by:

invalidReason in class Mission

Returns:

A reason for mission invalidity, or null if none found.

doMission

public Mission doMission(LogBuilder lb)

Performs the mission.

Specified by:

doMission in class Mission

Parameters:

lb - A LogBuilder to log to.

Returns:

The Mission to continue with, or null if the current mission has completed.

writeAttributes

protected void writeAttributes(FreeColXMLWriter xw)
                        throws javax.xml.stream.XMLStreamException

Write the attributes of this object to a stream. To be overridden if required by any object that has attributes and uses the toXML(FreeColXMLWriter, String) call.

Overrides:

writeAttributes in class Mission

Parameters:

xw - The FreeColXMLWriter to write to.

Throws:

javax.xml.stream.XMLStreamException - if there are any problems writing to the stream.

readAttributes

protected void readAttributes(FreeColXMLReader xr)
                       throws javax.xml.stream.XMLStreamException

Reads the attributes of this object from an XML stream.

Overrides:

readAttributes in class Mission

Parameters:

xr - The FreeColXMLReader to read from.

Throws:

javax.xml.stream.XMLStreamException - if there is a problem reading the stream.

getXMLTagName

public java.lang.String getXMLTagName()

Get the serialization tag for this object.

Specified by:

getXMLTagName in class FreeColObject

Returns:

The tag.
