Constructor Detail

RelationshipStore

public RelationshipStore(String fileName,
                         Map<?,?> config)

See AbstractStore#AbstractStore(String, Map)

Method Detail

accept

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

Specified by:

accept in interface RecordStore<RelationshipRecord>

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<RelationshipRecord>

Specified by:

getRecordSize in class AbstractStore

Returns:

The record size

getRecordHeaderSize

public int getRecordHeaderSize()

Specified by:

getRecordHeaderSize in interface RecordStore<RelationshipRecord>

close

public void close()

Description copied from class: CommonAbstractStore

Closes this store. This will cause all buffers and channels to be closed. Requesting an operation from after this method has been invoked is illegal and an exception will be thrown.

This method will start by invoking the CommonAbstractStore.closeStorage() method giving the implementing store way to do anything that it needs to do before the fileChannel is closed.

Specified by:

close in interface RecordStore<RelationshipRecord>

Overrides:

close in class CommonAbstractStore

createStore

public static void createStore(String fileName,
                               IdGeneratorFactory idGeneratorFactory)

Creates a new relationship store contained in fileName If filename is null or the file already exists an IOException is thrown.

Parameters:

fileName - File name of the new relationship store

Throws:

IOException - If unable to create relationship store or name null

getRecord

public RelationshipRecord getRecord(long id)

Specified by:

getRecord in interface RecordStore<RelationshipRecord>

forceGetRecord

public RelationshipRecord forceGetRecord(long id)

Specified by:

forceGetRecord in interface RecordStore<RelationshipRecord>

forceGetRaw

public RelationshipRecord forceGetRaw(long id)

Specified by:

forceGetRaw in interface RecordStore<RelationshipRecord>

getLightRel

public RelationshipRecord getLightRel(long id)

updateRecord

public void updateRecord(RelationshipRecord record,
                         boolean recovered)

updateRecord

public void updateRecord(RelationshipRecord record)

Specified by:

updateRecord in interface RecordStore<RelationshipRecord>

forceUpdateRecord

public void forceUpdateRecord(RelationshipRecord record)

Specified by:

forceUpdateRecord in interface RecordStore<RelationshipRecord>

getChainRecord

public RelationshipRecord getChainRecord(long relId)

getAllWindowPoolStats

public List<WindowPoolStats> getAllWindowPoolStats()

Specified by:

getAllWindowPoolStats in class AbstractStore

logIdUsage

public void logIdUsage(StringLogger logger)

Specified by:

logIdUsage in interface Store
