ResolvableRegionFactoryBean

public ResolvableRegionFactoryBean()

Method Details

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Initializes this ResolvableRegionFactoryBean after properties have been set by the Spring container.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

Exception - if initialization fails.

See Also:

• InitializingBean.afterPropertiesSet()
• createRegion(GemFireCache, String)

resolveRegionName

public String resolveRegionName()

Resolves the configured name of the Region.

Returns:

a String containing the name of the Region.

See Also:

• Region.getName()

createRegion

protected Region<K,V> createRegion(GemFireCache cache,
 String regionName)
                            throws Exception

Creates a new Region with the given name. This method gets called when a Region with the specified name does not already exist. By default, this method implementation throws a BeanInitializationException and it is expected that subclasses will override this method.

Parameters:

cache - reference to the GemFireCache.

regionName - name of the new Region.

Returns:

a new Region with the given name.

Throws:

BeanInitializationException - by default unless a subclass overrides this method.

Exception

See Also:

• GemFireCache
• Region

loadSnapshot

@NonNull
protected Region<K,V> loadSnapshot(@NonNull
 Region<K,V> region)

Loads data from the configured snapshot into the given Region.

Parameters:

region - Region to load; must not be null.

Returns:

the given Region.

Throws:

RuntimeException - if loading the snapshot fails.

See Also:

• Region.loadSnapshot(InputStream)
• Region

postProcess

protected Region<K,V> postProcess(Region<K,V> region)

Post-process the Region created by this PeerRegionFactoryBean.

Parameters:

region - Region to process.

See Also:

• Region

getObject

public Region<K,V> getObject()
                      throws Exception

Returns an object reference to the Region created by this ResolvableRegionFactoryBean.

Specified by:

getObject in interface FactoryBean<K>

Returns:

an object reference to the Region created by this ResolvableRegionFactoryBean.

Throws:

Exception

See Also:

• FactoryBean.getObject()
• Region
• getRegion()

getObjectType

public Class<?> getObjectType()

Returns the Class type of the Region produced by this ResolvableRegionFactoryBean.

Specified by:

getObjectType in interface FactoryBean<K>

Returns:

the Class type of the Region produced by this ResolvableRegionFactoryBean.

See Also:

• FactoryBean.getObjectType()

getCache

public GemFireCache getCache()

Returns a reference to the GemFireCache used to create the Region.

Returns:

a reference to the GemFireCache used to create the Region.

See Also:

• GemFireCache

setCache

public void setCache(GemFireCache cache)

Sets a reference to the GemFireCache used to create the Region.

Parameters:

cache - reference to the GemFireCache.

See Also:

• GemFireCache

setLookupEnabled

public void setLookupEnabled(@Nullable
 Boolean lookupEnabled)

getLookupEnabled

@Nullable
public Boolean getLookupEnabled()

isLookupEnabled

public boolean isLookupEnabled()

setName

public void setName(@NonNull
 String name)

Sets the name of the cache Region based on the bean 'name' attribute. If no Region is found with the given name, a new one will be created. If no name is given, the value of the 'beanName' property will be used.

Parameters:

name - Region name.

See Also:

• AbstractFactoryBeanSupport.setBeanName(String)
• Region.getFullPath()

setParent

public void setParent(@Nullable
 Region<?,?> parent)

Sets a reference to the parent Region making this FactoryBean represent a cache Sub-Region.

Parameters:

parent - reference to the parent Region.

See Also:

• Region

getParent

@Nullable
protected Region<?,?> getParent()

Returns a reference to the parent Region making this FactoryBean represent a cache Sub-Region.

Returns:

a reference to the parent Region, or null if this Region is not a Sub-Region.

See Also:

• Region

setRegion

protected void setRegion(@Nullable
 Region<K,V> region)

Sets a reference to the Region to be resolved by this Spring FactoryBean.

Parameters:

region - reference to the resolvable Region.

See Also:

• Region

getRegion

@Nullable
public Region<K,V> getRegion()

Returns a reference to the Region resolved by this Spring FactoryBean during the lookup operation; maybe a new Region.

Returns:

a reference to the Region resolved during lookup.

See Also:

• Region

setRegionName

public void setRegionName(@Nullable
 String regionName)

Sets the name of the cache Region. If no Region is found with the given name, a new one will be created. If no name is given, the value of the 'name' property will be used.

Parameters:

regionName - name of the Region.

See Also:

• setName(String)
• Region.getName()

setSnapshot

public void setSnapshot(@Nullable
 Resource snapshot)

Sets the snapshots used for loading a newly created region. That is, the snapshot will be used only when a new region is created - if the region already exists, no loading will be performed.

Parameters:

snapshot - the snapshot to set
