Constructor Detail

CacheDataDescriptionImpl

public CacheDataDescriptionImpl(boolean mutable,
                        boolean versioned,
                        Comparator versionComparator)

Constructs a CacheDataDescriptionImpl instance. Generally speaking, code should use one of the overloaded decode(org.hibernate.mapping.PersistentClass) methods rather than direct instantiation.

Parameters:

mutable - Is the described data mutable?

versioned - Is the described data versioned?

versionComparator - The described data's version value comparator (if versioned).

Method Detail

isMutable

public boolean isMutable()

Description copied from interface: CacheDataDescription

Is the data marked as being mutable?

Specified by:

isMutable in interface CacheDataDescription

Returns:

true if the data is mutable; false otherwise.

isVersioned

public boolean isVersioned()

Description copied from interface: CacheDataDescription

Is the data to be cached considered versioned? If true, it is illegal for CacheDataDescription.getVersionComparator() to return null.

Specified by:

isVersioned in interface CacheDataDescription

Returns:

true if the data is versioned; false otherwise.

getVersionComparator

public Comparator getVersionComparator()

Description copied from interface: CacheDataDescription

Get the comparator used to compare two different version values. May return null if CacheDataDescription.isVersioned() returns false.

Specified by:

getVersionComparator in interface CacheDataDescription

Returns:

The comparator for versions, or null

decode

public static CacheDataDescriptionImpl decode(PersistentClass model)

Builds a CacheDataDescriptionImpl from the mapping model of an entity class.

Parameters:

model - The mapping model.

Returns:

The constructed CacheDataDescriptionImpl

decode

public static CacheDataDescriptionImpl decode(EntityBinding model)

Builds a CacheDataDescriptionImpl from the mapping model of an entity class (using the new metamodel code).

Parameters:

model - The mapping model.

Returns:

The constructed CacheDataDescriptionImpl

decode

public static CacheDataDescriptionImpl decode(Collection model)

Builds a CacheDataDescriptionImpl from the mapping model of a collection

Parameters:

model - The mapping model.

Returns:

The constructed CacheDataDescriptionImpl

decode

public static CacheDataDescriptionImpl decode(PluralAttributeBinding model)

Builds a CacheDataDescriptionImpl from the mapping model of a collection (using the new metamodel code).

Parameters:

model - The mapping model.

Returns:

The constructed CacheDataDescriptionImpl
