    Whether the MetaDataFactory and MappingFactory should be set to strict mode. If strict mode is used a MetaDataFactory will only resolve MetaData (no JDBC mappings), and a MappingFactory will only resolve Mapping information.
    
    Returns:
    
    Whether strict mode should be used.
    
    Since:
    
    2.2.0
  - setMetaFactoriesAreStrict
```
public void setMetaFactoriesAreStrict(boolean metaFactoriesAreStrict)
```
    Set whether MetaDataFactories and MappingFactories will be strictly separate.
    
    Parameters:
    
    metaFactoriesAreStrict - True if the MetaDataFactory should only process metadata, and the MappingFactory should only process mappings.

  - getResetFlushFlagForCascadePersist
```
public boolean getResetFlushFlagForCascadePersist()
```
    Whether OpenJPA should reset the internal state (flush flag) when cascading a persist to another Entity. That is, when a flush is performed, OpenJPA keep state to indicate the flush has been performed. In certain cascade persist scenarios the fact that a flush has been performed prior to a cascade persist can cause certain entities to not be written to the database given the prior flush. This property, when set, will cause the flush flag to be reset in cascade scenarios. For more details see JIRA OPENJPA-2051
    
    Since:
    
    2.0.x
  - setResetFlushFlagForCascadePersist
```

  - isSingletonLifecycleEventManager
```
public boolean isSingletonLifecycleEventManager()
```
    Returns true if life cycle event manager is a singleton configuration.
  - setSingletonLifecycleEventManager
```
public void setSingletonLifecycleEventManager(boolean singleton)
```
    This property set whether each EntityManager has its own life cycle event manager. By default, each EntityManager only fires events to the registered listeners to the entities it manages. If the life cycle event manager is a singleton, events will be fired to listeners registered to all instances of EntityManager in the same persistence unit.
  - getFilterPCRegistryClasses
```
public boolean getFilterPCRegistryClasses()
```
    Whether the metadata processor should filter classes dispatched by the PCRegistry listener system.
  - setFilterPCRegistryClasses
```
public void setFilterPCRegistryClasses(boolean bool)
```
    Whether the metadata processor should filter classes dispatched by the PCRegistry listener system.
  - getReturnNullOnEmptyAggregateResult
```
public boolean getReturnNullOnEmptyAggregateResult()
```
    This property is used to specify whether the aggregate query functions SUM, AVG, MAX, and MIN return null if there is no query result. This will occur if no rows are returned for the specified query predicate. The default is false, meaning that 0 will be returned for functions operating on numeric data. In compliance with the JPA specification, the default value is true.
    
    Returns:
    
    true if the result of an aggregate with an empty query result returns null.
    
    Since:
  - setReturnNullOnAggregateResult
```
public void setReturnNullOnAggregateResult(boolean returnNullOnEmptyAggregateResult)
```
    This property is used to specify whether the aggregate query functions SUM, AVG, MAX, and MIN return null if there is no query result. This will occur if no rows are returned for the specified query predicate. The default is false, meaning that 0 will be returned for functions operating on numeric data. In compliance with the JPA specification, the default value is true.
    
    Parameters:
    
    returnNullOnAggregate - whether OpenJPA will return null for aggregate expressions when the query result is empty.
    
    Since:
  - getCacheNonDefaultFetchPlanQueries
```
public boolean getCacheNonDefaultFetchPlanQueries()
```
    Whether the SQL generated for queries executed with a modified fetch plan are cached.
  - setCacheNonDefaultFetchPlanQueries
```
public void setCacheNonDefaultFetchPlanQueries(boolean bool)
```
    Whether the SQL generated for queries executed with a modified fetch plan are cached.
