Method Details

addAsync

RFuture<Boolean> addAsync(V value,
 long ttl,
 TimeUnit unit)

Stores value with specified time to live. Value expires after specified time to live.

Parameters:

value - to add

ttl - - time to live for key\value entry. If 0 then stores infinitely.

unit - - time unit

Returns:

true if value has been added. false if value already been in collection.

sizeAsync

RFuture<Integer> sizeAsync()

Returns the number of elements in cache. This number can reflects expired elements too due to non realtime cleanup process.

Specified by:

sizeAsync in interface RCollectionAsync<V>

Returns:

size of set

tryAddAsync

@Deprecated
RFuture<Boolean> tryAddAsync(long ttl,
 TimeUnit unit,
 V... values)

Deprecated.

Use addIfAbsentAsync(Duration, Object) instead

Parameters:

values - - values to add

ttl - - time to live for value. If 0 then stores infinitely.

unit - - time unit

Returns:

true if elements successfully added, otherwise false.

addIfAbsentAsync

RFuture<Boolean> addIfAbsentAsync(Duration ttl,
 V object)

Adds element to this set only if has not been added before.

Requires Redis 3.0.2 and higher.

Parameters:

ttl - - object ttl

object - - object itself

Returns:

true if element added and false if not.

addIfExistsAsync

RFuture<Boolean> addIfExistsAsync(Duration ttl,
 V object)

Adds element to this set only if it's already exists.

Requires Redis 3.0.2 and higher.

Parameters:

ttl - - object ttl

object - - object itself

Returns:

true if element added and false if not.

addIfLessAsync

RFuture<Boolean> addIfLessAsync(Duration ttl,
 V object)

Adds element to this set only if new ttl less than current ttl of existed element.

Requires Redis 6.2.0 and higher.

Parameters:

ttl - - object ttl

object - - object itself

Returns:

true if element added and false if not.

addIfGreaterAsync

RFuture<Boolean> addIfGreaterAsync(Duration ttl,
 V object)

Adds element to this set only if new ttl greater than current ttl of existed element.

Requires Redis 6.2.0 and higher.

Parameters:

ttl - - object ttl

object - - object itself

Returns:

true if element added and false if not.

addAllAsync

RFuture<Integer> addAllAsync(Map<V,Duration> objects)

Adds all elements contained in the specified map to this sorted set. Map contains of ttl mapped by object.

Parameters:

objects - - map of elements to add

Returns:

amount of added elements, not including already existing in this sorted set

addAllIfAbsentAsync

RFuture<Integer> addAllIfAbsentAsync(Map<V,Duration> objects)

Adds elements to this set only if they haven't been added before.

Requires Redis 3.0.2 and higher.

Parameters:

objects - map of elements to add

Returns:

amount of added elements

addAllIfExistAsync

RFuture<Integer> addAllIfExistAsync(Map<V,Duration> objects)

Adds elements to this set only if they already exist.

Requires Redis 3.0.2 and higher.

Parameters:

objects - map of elements to add

Returns:

amount of added elements

addAllIfGreaterAsync

RFuture<Integer> addAllIfGreaterAsync(Map<V,Duration> objects)

Adds elements to this set only if new ttl greater than current ttl of existed elements.

Requires Redis 6.2.0 and higher.

Parameters:

objects - map of elements to add

Returns:

amount of added elements

addAllIfLessAsync

RFuture<Integer> addAllIfLessAsync(Map<V,Duration> objects)

Adds elements to this set only if new ttl less than current ttl of existed elements.

Requires Redis 6.2.0 and higher.

Parameters:

objects - map of elements to add

Returns:

amount of added elements
