Method Detail

get

V get(K key)

Gets an entry from the cache.

Parameters:

key - the key whose associated value is to be returned

Returns:

the element, or null, if it does not exist.

put

void put(K key,
         V val)

Associates the specified value with the specified key in the cache.

Parameters:

key - key with which the specified value is to be associated

val - value to be associated with the specified key.

size

int size(CachePeekMode... peekModes)

Gets the number of all entries cached across all nodes.

Parameters:

peekModes - Optional peek modes. If not provided, then total cache size is returned.

getAll

Map<K,V> getAll(Set<? extends K> keys)

Gets a collection of entries from the Ignite cache, returning them as Map of the values associated with the set of keys requested.

Parameters:

keys - The keys whose associated values are to be returned.

Returns:

A map of entries that were found for the given keys.

putAll

void putAll(Map<? extends K,? extends V> map)

Copies all of the entries from the specified map to the Ignite cache.

Parameters:

map - Mappings to be stored in this cache.

remove

boolean remove(K key)

Removes the mapping for a key from this cache if it is present.

Parameters:

key - Key whose mapping is to be removed from the cache.

Returns:

false if there was no matching key.

removeAll

void removeAll(Set<? extends K> keys)

Removes entries for the specified keys.

Parameters:

keys - The keys to remove.

clear

void clear()

Clears the contents of the cache.

withExpiryPolicy

IgniteCacheProxy<K,V> withExpiryPolicy(javax.cache.expiry.ExpiryPolicy expirePlc)

Returns cache with the specified expired policy set. This policy will be used for each operation invoked on the returned cache.

Returns:

Cache instance with the specified expiry policy set.

query

<R> QueryCursor<R> query(Query<R> qry)

Execute SQL query and get cursor to iterate over results.

Parameters:

qry - SQL query.

Returns:

Query result cursor.

containsKey

boolean containsKey(K key)

Determines if the ClientCache contains an entry for the specified key.

Parameters:

key - key whose presence in this cache is to be tested.

Returns:

true if this map contains a mapping for the specified key.
