Class AbstractSimpleDbLoggerFactory<L extends org.refcodes.logger.Logger<T>,T>

java.lang.Object

org.refcodes.logger.alt.simpledb.factories.impls.AbstractSimpleDbLoggerFactory<L,T>

Type Parameters:

L - The type (sub-type) of the Logger to be created.

T - The type of the Record instances managed by the Logger.

All Implemented Interfaces:

org.refcodes.factory.factories.TypedLookupIdFactory<L>, org.refcodes.logger.factories.LoggerFactory<L>

Direct Known Subclasses:

AbstractSimpleDbQueryLoggerFactory, SimpleDbLoggerFactoryImpl

public abstract class AbstractSimpleDbLoggerFactory<L extends org.refcodes.logger.Logger<T>,T>
extends Object
implements org.refcodes.logger.factories.LoggerFactory<L>

The AbstractSimpleDbLoggerFactory implements the LoggerFactory and creates Logger instances using the SimpleDB NoSQL engine from Amazon. The LoggerFactory methods createInstance(String) and createInstance(String) actually return LoggerSimpleDbImpl instances being configured to use an Amazon SimpleDB domain name constructed from an Amazon SimpleDB domain prefix (provided to the constructor) and suffix (provided to the factory methods).

Method Detail

createInstance

public abstract L createInstance(String aDomainSuffix)

Creates a Logger instance using Amazon SimpleDB as the physical data sink. The Amazon SimpleDB domain name is generated from the SimpleDB domain prefix as passed via the constructor and the SimpleDB domain suffix as passed as argument.

Specified by:

createInstance in interface org.refcodes.factory.factories.TypedLookupIdFactory<L extends org.refcodes.logger.Logger<T>>

Parameters:

aDomainSuffix - The Amazon SimpleDB domain name's suffix. The prefix is provided via the constructor.

createInstance

public L createInstance(String aDomainSuffix,
                        Properties aProperties)

Creates a Logger instance using Amazon SimpleDB as the physical data sink. The Amazon SimpleDB domain name is generated from the SimpleDB domain prefix as passed via the constructor and the SimpleDB domain suffix as passed as argument.

Specified by:

createInstance in interface org.refcodes.factory.factories.TypedLookupIdFactory<L extends org.refcodes.logger.Logger<T>>

Parameters:

aDomainSuffix - The Amazon SimpleDB domain name's suffix. The prefix is provided via the constructor.

aProperties - Additional properties to configure the Logger instance, them properties are currently not supported!
