Method Detail

accept

public void accept(RecordStore.Processor processor,
                   PropertyRecord record)

Specified by:

accept in interface RecordStore<PropertyRecord>

initStorage

protected void initStorage()

Description copied from class: CommonAbstractStore

Called from the constructor after the end header has been checked. The store implementation can setup it's persistence windows and other resources that are needed by overriding this implementation.

This default implementation does nothing.

Overrides:

initStorage in class CommonAbstractStore

setRecovered

protected void setRecovered()

Overrides:

setRecovered in class CommonAbstractStore

unsetRecovered

protected void unsetRecovered()

Overrides:

unsetRecovered in class CommonAbstractStore

closeStorage

protected void closeStorage()

Description copied from class: CommonAbstractStore

This method should close/release all resources that the implementation of this store has allocated and is called just before the close() method returns. Override this method to clean up stuff created in CommonAbstractStore.initStorage() method.

This default implementation does nothing.

Overrides:

closeStorage in class CommonAbstractStore

flushAll

public void flushAll()

Overrides:

flushAll in class CommonAbstractStore

getTypeDescriptor

public String getTypeDescriptor()

Description copied from class: CommonAbstractStore

Returns the type and version that identifies this store.

Specified by:

getTypeDescriptor in interface Store

Specified by:

getTypeDescriptor in class CommonAbstractStore

Returns:

This store's implementation type and version identifier

getRecordSize

public int getRecordSize()

Description copied from class: AbstractStore

Returns the fixed size of each record in this store.

Specified by:

getRecordSize in interface RecordStore<PropertyRecord>

Specified by:

getRecordSize in class AbstractStore

Returns:

The record size
