                         GridCacheMapEntry next,
                         int hdrId)

Parameters:

ctx - Cache context.

key - Cache key.

hash - Key hash value.

val - Entry value.

next - Next entry in the linked list.

hdrId - Header ID.

Method Detail

resetFromPrimary

public void resetFromPrimary(CacheObject val,
                    GridCacheVersion ver)

Sets value to detached entry so it can be retrieved in transactional gets.

Parameters:

val - Value.

ver - Version.

unswap

@Nullable
public CacheObject unswap(boolean needVal)
                   throws IgniteCheckedException

Unswaps an entry.

Specified by:

unswap in interface GridCacheEntryEx

Overrides:

unswap in class GridCacheMapEntry

Parameters:

needVal - If false then do not to deserialize value during unswap.

Returns:

Value.

Throws:

IgniteCheckedException - If failed.

value

protected void value(@Nullable
         CacheObject val)

Sets entry value. If off-heap value storage is enabled, will serialize value to off-heap.

Overrides:

value in class GridCacheMapEntry

Parameters:

val - Value to store.

valueBytesUnlocked

protected CacheObject valueBytesUnlocked()

Overrides:

valueBytesUnlocked in class GridCacheMapEntry

Returns:

Value bytes.

updateIndex

protected void updateIndex(CacheObject val,
               long expireTime,
               GridCacheVersion ver,
               CacheObject old)
                    throws IgniteCheckedException

Updates cache index.

Overrides:

updateIndex in class GridCacheMapEntry

Parameters:

val - Value.

expireTime - Expire time.

ver - New entry version.

old - Previous value.

Throws:

IgniteCheckedException - If update failed.

clearIndex

protected void clearIndex(CacheObject val)
                   throws IgniteCheckedException

Clears index.

Overrides:

clearIndex in class GridCacheMapEntry

Parameters:

val - Previous value (if needed for index update).

Throws:

IgniteCheckedException - If failed.

detached

public boolean detached()

Specified by:

detached in interface GridCacheEntryEx

Overrides:

detached in class GridCacheMapEntry

Returns:

False if entry belongs to cache map, true if this entry was created in colocated cache and node is not primary for this key.

toString

public String toString()

Overrides:

toString in class GridDistributedCacheEntry

addRemoved

public boolean addRemoved(GridCacheVersion ver)

Overrides:

addRemoved in class GridDistributedCacheEntry

Parameters:

ver - Lock version.

Returns:

True if removed.
