Constructor Details

EvictionPolicyMetaData

protected EvictionPolicyMetaData(EvictionAttributes evictionAttributes)

Constructs an instance of EvictionConfiguration.EvictionPolicyMetaData initialized with the given EvictionAttributes applying to all Regions.

Parameters:

evictionAttributes - EvictionAttributes specifying the Eviction policy configuration for a Region.

See Also:

• EvictionAttributes
• EvictionPolicyMetaData(EvictionAttributes, String[])

EvictionPolicyMetaData

protected EvictionPolicyMetaData(EvictionAttributes evictionAttributes,
 String[] regionNames)

Constructs an instance of EvictionConfiguration.EvictionPolicyMetaData initialized with the given EvictionAttributes to apply to the specific Regions.

Parameters:

evictionAttributes - EvictionAttributes specifying the Eviction policy configuration for a Region.

regionNames - names of Regions on which the Eviction policy is applied.

See Also:

• EvictionAttributes

fromDefaults

protected static EvictionConfiguration.EvictionPolicyMetaData fromDefaults()

resolveObjectSizer

protected static ObjectSizer resolveObjectSizer(String objectSizerName,
 ApplicationContext applicationContext)

resolveThreshold

protected static Integer resolveThreshold(int maximum,
 EvictionPolicyType type)

Resolves the Eviction policy threshold (a.k.a. maximum) based on the EvictionPolicyType. For instance EvictionPolicyType.HEAP_PERCENTAGE does not support maximum/threshold since the settings are determined by the GemFire/Geode cache critical heap percentage and eviction heap percentage System property settings.

Parameters:

maximum - integer value specifying the configured Eviction threshold.

type - EvictionPolicyType specifying the type of Eviction algorithm.

Returns:

a resolved value for the Eviction maximum/threshold.

• EvictionPolicyType

accepts

protected boolean accepts(@Nullable
 Object regionFactoryBean)

Determines whether the given Object (e.g. Spring bean) is accepted for Eviction policy configuration.

Parameters:

regionFactoryBean - Object being evaluated as an Eviction policy configuration candidate.

Returns:

a boolean value indicating whether the Object is accepted for Eviction policy configuration.

See Also:

• EvictionConfiguration.isRegionFactoryBean(Object)
• resolveRegionName(Object)
• accepts(Supplier)

accepts

protected boolean accepts(@Nullable
 Region<?,?> region)

Determines whether the given Region is accepted for Eviction policy configuration.

Parameters:

region - Region evaluated for Eviction policy configuration.

Returns:

a boolean value indicating whether the given Region is accepted for Eviction policy configuration.

See Also:

• Region
• accepts(Supplier)

accepts

protected boolean accepts(Supplier<String> regionName)

Determine whether the Region identified by name is accepted for Eviction policy configuration.

Parameters:

regionName - name of the Region targeted for Eviction policy configuration.

Returns:

a boolean value if the named Region is accepted for Eviction policy configuration.

resolveRegionName

protected String resolveRegionName(Object regionFactoryBean)

Resolves the name of a given Region from the corresponding ResolvableRegionFactoryBean object.

Parameters:

regionFactoryBean - ResolvableRegionFactoryBean from which to resolve the Region name.

Returns:

the resolved name of the Region created from the given ResolvableRegionFactoryBean.

See Also:

• ResolvableRegionFactoryBean.resolveRegionName()

setEvictionAttributes

protected EvictingRegionFactoryBean setEvictionAttributes(EvictingRegionFactoryBean regionFactoryBean)

Sets the EvictionAttributes on the PeerRegionFactoryBean or ClientRegionFactoryBean used to create the targeted Region.

Parameters:

regionFactoryBean - PeerRegionFactoryBean or ClientRegionFactoryBean on which to set the EvictionAttributes encapsulating the Eviction policy for the targeted Region.

Returns:

the regionFactoryBean.

See Also:

• EvictingRegionFactoryBean.setEvictionAttributes(EvictionAttributes)
• EvictionAttributes
• getEvictionAttributes()

getEvictionAttributes

protected EvictionAttributes getEvictionAttributes()

Returns an instance of the EvictionAttributes specifying the Eviction policy configuration captured in this Eviction policy meta-data.

Returns:

an instance of the EvictionAttributes specifying the Region Eviction policy configuration.

Throws:

IllegalStateException - if the EvictionAttributes were not properly initialized.
