resolveObjectSizer

protected static com.gemstone.gemfire.cache.util.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.

Returns:

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

Throws:

IllegalStateException - if the EvictionAttributes were not properly initialized.

resolveRegionName

protected String resolveRegionName(Object regionFactoryBean)

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

Parameters:
