Method Detail

comparator

public Comparator comparator()

Description copied from interface:
Returns the Comparator associated with this SortedMap, or null if it uses its keys' natural ordering.

Specified by:

comparator in interface SortedMap

subMap

public SortedMap subMap(java.lang.Object fromKey,
                        java.lang.Object toKey)

Description copied from interface:
Returns a view of the portion of this SortedMap whose keys range from fromKey, inclusive, to toKey, exclusive. The returned SortedMap is backed by this SortedMap, so changes in the returned SortedMap are reflected in this SortedMap, and vice-versa. The returned Map supports all optional Map operations.

The Map returned by this method will throw an IllegalArgumentException if the user attempts to insert a key outside the specified range.

Specified by:

subMap in interface SortedMap

headMap

public SortedMap headMap(java.lang.Object toKey)

Description copied from interface:
Returns a view of the portion of this SortedMap whose keys are strictly less than toKey. The returned SortedMap is backed by this SortedMap, so changes in the returned SortedMap are reflected in this SortedMap, and vice-versa. The returned Map supports all optional Map operations. The Map returned by this method will throw an IllegalArgumentException if the user attempts to insert a key outside the specified range.

Specified by:

headMap in interface SortedMap

tailMap

public SortedMap tailMap(java.lang.Object fromKey)

Description copied from interface:
Returns a view of the portion of this SortedMap whose keys are greater than or equal to fromKey. The returned SortedMap is backed by this SortedMap, so changes in the returned SortedMap are reflected in this SortedMap, and vice-versa. The returned Map supports all optional Map operations.

The Map returned by this method will throw an IllegalArgumentException if the user attempts to insert a key outside the specified range.

Specified by:

tailMap in interface SortedMap

firstKey

public java.lang.Object firstKey()

Description copied from interface:
Returns the first (lowest) key currently in this SortedMap.

Specified by:

firstKey in interface SortedMap

lastKey

public java.lang.Object lastKey()

Description copied from interface:
Returns the last (highest) key currently in this SortedMap.

Specified by:

lastKey in interface SortedMap
