public class BerkeleyDBBinaryStoreManager extends Base implements BinaryStoreManager, XmlConfigurable
The usage pattern for BinaryStoreManagers is simply to instantiate them, use them to allocate a single BinaryStore instance, and forget about them. This implementation maintains knowledge of previously created Berkeley DB Environments via a static DatabaseFactoryManager, thus ensuring a minimum number of Environments are created, regardless of the life-cycle of the BinaryStoreManager.

public BerkeleyDBBinaryStoreManager()
The temporary Environment directory will be placed under $tmp/coherence/bdb, where $tmp is the system defined temp directory.
Configuration is performed via XmlConfigurable interface.
public BerkeleyDBBinaryStoreManager(File dirParent, String sDbName)
A temporary directory will be created beneath the specified parent directory, for use by the Berkeley Environment.
Additional configuration is performed via XmlConfigurable interface.
dirParent - the parent directory for the EnvironmentsDbName - the name of the database to store the cache's data
within. This value is only specified when using
a persistent store.setConfig(com.tangosol.run.xml.XmlElement)public String toString()
public boolean equals(Object that)
Two instances are considered to be equal if their underlying configuration is identical, or if they have reference equality.
public int hashCode()
The hash code is computed as the sum of the hash codes of the Objects making up the BerkeleyDBBinaryStoreManager's configuration.
