getValue

public java.lang.Object getValue(java.lang.String key)

Description copied from interface: AVList

Returns the value for a specified key.

Specified by:

getValue in interface AVList

Overrides:

getValue in class AVListImpl

Parameters:

key - the attribute name. May not be null.

Returns:

the attribute value if one exists in the collection, otherwise null.

isFinalLevel

public final boolean isFinalLevel(int levelNum)

isLevelEmpty

public final boolean isLevelEmpty(int levelNumber)

isResourceAbsent

public final boolean isResourceAbsent(Tile tile)

Indicates whether a tile has been marked as absent.

Parameters:

tile - The tile in question.

Returns:

true if the tile is marked absent, otherwise false.

Throws:

java.lang.IllegalArgumentException - if tile is null

isResourceAbsent

public final boolean isResourceAbsent(TileKey tileKey)

Indicates whether a tile has been marked as absent.

Parameters:

tileKey - The key of the tile in question.

Returns:

true if the tile is marked absent, otherwise false.

Throws:

java.lang.IllegalArgumentException - if tile is null

markResourceAbsent

public final void markResourceAbsent(Tile tile)

Instructs the level set that a tile is likely to be absent.

Parameters:

tile - The tile to mark as having an absent resource.

Throws:

java.lang.IllegalArgumentException - if tile is null

setExpiryTime

public void setExpiryTime(long expiryTime)

setValue

public java.lang.Object setValue(java.lang.String key,
                                 java.lang.Object value)

Description copied from interface: AVList

Adds a key/value pair to the list. Replaces an existing key/value pair if the list already contains the key.

Specified by:

setValue in interface AVList

Overrides:

setValue in class AVListImpl

Parameters:

key - the attribute name. May not be null.

value - the attribute value. May be null, in which case any existing value for the key is removed from the collection.

Returns:

previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.

unmarkResourceAbsent

public final void unmarkResourceAbsent(Tile tile)

Removes the absent-tile mark associated with a tile, if one is associatied.

Parameters:

tile - The tile to unmark.

Throws:

java.lang.IllegalArgumentException - if tile is null
