Constructor Detail

CacheObjectImpl

public CacheObjectImpl()

CacheObjectImpl

public CacheObjectImpl(Object val,
                       byte[] valBytes)

Parameters:

val - Value.

valBytes - Value bytes.

Method Detail

isPlatformType

public boolean isPlatformType()

Gets flag indicating whether object value is a platform type. Platform types will be automatically deserialized on public API cache operations regardless whether IgniteCache.withKeepBinary() is used or not.

Returns:

Platform type flag.

value

@Nullable
public <T> T value(CacheObjectValueContext ctx,
                   boolean cpy)

Parameters:

ctx - Context.

cpy - If true need to copy value.

Returns:

Value.

value

@Nullable
public <T> T value(CacheObjectValueContext ctx,
                   boolean cpy,
                   ClassLoader ldr)

Deserializes a value from an internal representation.

Parameters:

ctx - Context.

cpy - If true need to copy value.

ldr - Class loader, if it is null, default class loader will be used.

Returns:

Value.

valueBytes

public byte[] valueBytes(CacheObjectValueContext ctx)
                  throws IgniteCheckedException

Parameters:

ctx - Context.

Returns:

Value bytes.

Throws:

IgniteCheckedException - If failed.

prepareMarshal

public void prepareMarshal(CacheObjectValueContext ctx)
                    throws IgniteCheckedException

Parameters:

ctx - Context.

Throws:

IgniteCheckedException - If failed.

finishUnmarshal

public void finishUnmarshal(CacheObjectValueContext ctx,
                            ClassLoader ldr)
                     throws IgniteCheckedException

Parameters:

ctx - Context.

ldr - Class loader.

Throws:

IgniteCheckedException - If failed.

onAckReceived

public void onAckReceived()

Method called when ack message received.

directType

public short directType()

Gets message type.

Returns:

Message type.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

prepareForCache

public CacheObject prepareForCache(CacheObjectContext ctx)

Prepares cache object for cache (e.g. copies user-provided object if needed).

Parameters:

ctx - Cache context.

Returns:

Instance to store in cache.
