Key whose mapping is to be removed from cache.
Previous value associated with specified key, or null
if there was no value for this key.

Retrieves value mapped to the specified key from cache. The return value of null
means entry did not pass the provided filter or cache has no mapping for the key.

IgniteCache.get(...)
Stores given key-value pair in cache.
Stores given key-value pair in cache. If filters are provided, then entries will be stored in cache only if they pass the filter. Note that filter check is atomic, so value stored in cache is guaranteed to be consistent with the filters.
If write-through is enabled, the stored value will be persisted to GridCacheStore
via GridCacheStore#put(String, GridCacheTx, Object, Object) method.
This method is transactional and will enlist the entry into ongoing transaction if there is one.
Key-Value pair to store in cache.
Previous value associated with specified key, or null
if entry did not pass the filter, or if there was no mapping for the key in swap
or in persistent storage.
IgniteCache#put(...)
Stores given key-value pairs from the sequence in cache.
Stores given key-value pairs from the sequence in cache.
If write-through is enabled, the stored values will be persisted to GridCacheStore
via GridCacheStore#putAll(String, GridCacheTx, Map) method.

IgniteCache#putx(...)
Removes given key mapping from cache.
Removes given key mapping from cache. If cache previously contained value for the given key,
then this value is returned. Otherwise, in case of CacheMode#REPLICATED caches,
the value will be loaded from swap and, if it's not there, and read-through is allowed,
from the underlying GridCacheStore storage. In case of CacheMode#PARTITIONED
caches, the value will be loaded from the primary node, which in its turn may load the value
from the swap storage, and consecutively, if it's not in swap and read-through is allowed,
from the underlying persistent storage. If value has to be loaded from persistent
storage, GridCacheStore#load(String, GridCacheTx, Object) method will be used.
If the returned value is not needed, method removex$(...) should
always be used instead of this one to avoid the overhead associated with returning of the
previous value.
If write-through is enabled, the value will be removed from 'GridCacheStore'
via GridCacheStore#remove(String, GridCacheTx, Object) method.
This method is transactional and will enlist the entry into ongoing transaction if there is one.

Creates and executes ad-hoc SCAN query returning its result.
Creates and executes ad-hoc SCAN query returning its result.
Note that if query is executed more than once (potentially with different
arguments) it is more performant to create query via standard mechanism
and execute it multiple times with different arguments. The analogy is
similar to JDBC PreparedStatement. Note also that this function will return
all results at once without pagination and therefore memory limits should be
taken into account.
Note that query value class will be taken implicitly as exact type V of this
cache projection.

Overview
Defines Scalar "pimp" for
IgniteCacheon Java side.Essentially this class extends Java
IgniteCacheinterface with Scala specific API adapters using primarily implicit conversions defined inScalarConversionsobject. What it means is that you can use functions defined in this class on object of JavaIgniteCachetype. Scala will automatically (implicitly) convert it into Scalar's pimp and replace the original call with a call on that pimp.Note that Scalar provide extensive library of implicit conversion between Java and Scala Ignite counterparts in
ScalarConversionsobjectSuffix '$' In Names
Symbol
$is used in names when they conflict with the names in the base Java class that Scala pimp is shadowing or with Java package name that your Scala code is importing. Instead of giving two different names to the same function we've decided to simply mark Scala's side method with$suffix.
