getHighestRank

public int getHighestRank()

Description copied from interface: MergeMap

Returns the highest rank of the values in the map.

Specified by:

getHighestRank in interface MergeMap<K,AsConfigurationHolder<T extends AbstractAsConfiguration,R extends AbstractAsConfiguration>>

Returns:

the highest rank of the values in the map

getLowestRank

public int getLowestRank()

Description copied from interface: MergeMap

Returns the lowest rank of the values in the map.

Specified by:

getLowestRank in interface MergeMap<K,AsConfigurationHolder<T extends AbstractAsConfiguration,R extends AbstractAsConfiguration>>

Returns:

the lowest rank of the values in the map

mergeBefore

public AsConfigurationHolder<T,R> mergeBefore(K key,
                                              AsConfigurationHolder<T,R> value)

Description copied from interface: MergeMap

Associates the given value with the given key in this map. The new value is added with an higher rank.

Specified by:

mergeBefore in interface MergeMap<K,AsConfigurationHolder<T extends AbstractAsConfiguration,R extends AbstractAsConfiguration>>

Parameters:

key - - the key

value - - the value

Returns:

the previous value, or null if there was no mapping for the key

mergeBefore

public void mergeBefore(MergeMap<K,AsConfigurationHolder<T,R>> source,
                        MergeFunction<K,AsConfigurationHolder<T,R>> mergeFunction)

Description copied from interface: MergeMap

Merges both maps, all entries from source map are added to this map. The new values are added with an higher rank, the rank hierarchy from the source map is preserved. If the merge function returns null, the mapping is removed.

Specified by:

mergeBefore in interface MergeMap<K,AsConfigurationHolder<T extends AbstractAsConfiguration,R extends AbstractAsConfiguration>>

Parameters:

source - - the source map

mergeFunction - - the merge function

mergeAfter

public AsConfigurationHolder<T,R> mergeAfter(K key,

Description copied from interface: MergeMap

Associates the given value with the given key in this map. The new value is added with a lower rank.

Specified by:

mergeAfter in interface MergeMap<K,AsConfigurationHolder<T extends AbstractAsConfiguration,R extends AbstractAsConfiguration>>

Parameters:

key - - the key

value - - the value

Returns:

the previous value, or null if there was no mapping for the key
