Method Detail

copyOnGet

boolean copyOnGet()

Returns:

Copy on get flag.

storeValue

boolean storeValue()

Returns:

True if should store unmarshalled value in cache.

addDeploymentInfo

boolean addDeploymentInfo()

Returns:

True if deployment info should be associated with the objects of this cache.

binaryEnabled

boolean binaryEnabled()

Returns:

Binary enabled flag.

binaryContext

BinaryContext binaryContext()

Returns:

Binary context.

waitMetadataWriteIfNeeded

void waitMetadataWriteIfNeeded(int typeId)

Forces caller thread to wait for binary metadata write operation for given type ID. In case of in-memory mode this method becomes a No-op as no binary metadata is written to disk in this mode.

Parameters:

typeId - ID of binary type to wait for metadata write operation.

classLoader

@Nullable
@Nullable ClassLoader classLoader()

Returns:

User's class loader.

globalLoader

ClassLoader globalLoader()

Gets distributed class loader.

Returns:

Cache class loader.

log

IgniteLogger log(Class<?> cls)

Parameters:

cls - Class

Returns:

Logger for class.

marshal

byte[] marshal(Object val)
        throws IgniteCheckedException

Parameters:

val - Value.

Returns:

Value bytes.

Throws:

IgniteCheckedException - If failed.

unmarshal

Object unmarshal(byte[] bytes,
                 ClassLoader clsLdr)
          throws IgniteCheckedException

Parameters:

bytes - Bytes.

clsLdr - Class loader.

Returns:

Unmarshalled object.

Throws:

IgniteCheckedException - If failed.

isPeerClassLoadingEnabled

boolean isPeerClassLoadingEnabled()

Returns:

true if peer class loading is enabled, false otherwise.

transformIfNecessary

default byte[] transformIfNecessary(byte[] bytes)

Transforms bytes according to CacheObjectTransformerProcessor when specified.

Parameters:

bytes - Given bytes.

Returns:

Transformed bytes.

transformIfNecessary

byte[] transformIfNecessary(byte[] bytes,
                            int offset,
                            int length)

Transforms bytes according to CacheObjectTransformerProcessor when specified.

Parameters:

bytes - Given bytes.

offset - Index to start from.

length - Data length.

Returns:

Transformed bytes.

restoreIfNecessary

byte[] restoreIfNecessary(byte[] bytes)

Restores transformed bytes if necessary.

Parameters:

bytes - Given bytes.

Returns:

Restored bytes.
