Method Summary

Modifier and Type	Method and Description
default R	insert(SetAbsentEntry<K> absentEntry) Inserts the new entry into the set, of the key from the given insertion context (absentEntry).
default R	remove(SetEntry<K> entry) Removes the given entry from the set.

Method Detail

remove

default R remove(@NotNull
                 SetEntry<K> entry)

Removes the given entry from the set. Note: default implementation calls SetEntry.doRemove() on the given entry and returns null.

Parameters:

entry - the entry to remove

Returns:

result of operation, understandable by higher-level SPIs

Throws:

IllegalStateException - if some locking/state conditions required to perform remove operation are not met

RuntimeException - if removal was unconditionally unsuccessful due to any reason

insert

default R insert(@NotNull
                 SetAbsentEntry<K> absentEntry)

Inserts the new entry into the set, of the key from the given insertion context (absentEntry). Note: default implementation calls SetAbsentEntry.doInsert() and returns null.

Returns:

result of operation, understandable by higher-level SPIs

Throws:

IllegalStateException - if some locking/state conditions required to perform insertion operation are not met

RuntimeException - if insertion was unconditionally unsuccessful due to any reason
