Constructor Details

RowProcessingStateStandardImpl

public RowProcessingStateStandardImpl(JdbcValuesSourceProcessingStateStandardImpl resultSetProcessingState,
 ExecutionContext executionContext,
 RowReader<?> rowReader,
 JdbcValues jdbcValues)

Method Details

getJdbcValuesSourceProcessingState

public JdbcValuesSourceProcessingState getJdbcValuesSourceProcessingState()

Description copied from interface: RowProcessingState

Access to the state related to the overall processing of the results.

Specified by:

getJdbcValuesSourceProcessingState in interface RowProcessingState

determineEffectiveLockMode

public LockMode determineEffectiveLockMode(String alias)

Specified by:

determineEffectiveLockMode in interface RowProcessingState

needsResolveState

public boolean needsResolveState()

Specified by:

needsResolveState in interface RowProcessingState

getInitializerData

public <T extends InitializerData> T getInitializerData(int initializerId)

Specified by:

getInitializerData in interface RowProcessingState

setInitializerData

public void setInitializerData(int initializerId,
 InitializerData state)

Specified by:

setInitializerData in interface RowProcessingState

getRowReader

public RowReader<?> getRowReader()

Description copied from interface: RowProcessingState

todo (6.0) : do we want this here? Depends how we handle caching assembler / result memento

Specified by:

getRowReader in interface RowProcessingState

next

public boolean next()

previous

public boolean previous()

scroll

public boolean scroll(int i)

position

public boolean position(int i)

getPosition

public int getPosition()

isBeforeFirst

public boolean isBeforeFirst()

beforeFirst

public void beforeFirst()

isFirst

public boolean isFirst()

first

public boolean first()

last

public boolean last()

isLast

public boolean isLast()

afterLast

public void afterLast()

isAfterLast

public boolean isAfterLast()

getJdbcValue

public Object getJdbcValue(int position)

Description copied from interface: RowProcessingState

Retrieve the value corresponding to the given index as part of the "current JDBC row". We read all the ResultSet values for the given row one time and store them into an array internally based on the principle that multiple accesses to this array will be significantly faster than accessing them from the ResultSet potentially multiple times.

Specified by:

getJdbcValue in interface RowProcessingState

registerNonExists

public void registerNonExists(EntityFetch fetch)

Specified by:

registerNonExists in interface RowProcessingState

isQueryCacheHit

public boolean isQueryCacheHit()

Specified by:

isQueryCacheHit in interface RowProcessingState

finishRowProcessing

public void finishRowProcessing(boolean wasAdded)

Description copied from interface: RowProcessingState

Callback at the end of processing the current "row"

Specified by:

finishRowProcessing in interface RowProcessingState

afterStatement

public void afterStatement(LogicalConnectionImplementor logicalConnection)

Description copied from interface: ExecutionContext

Hook to allow delaying calls to LogicalConnectionImplementor.afterStatement(). Mainly used in the case of batching and multi-table mutations

Specified by:

afterStatement in interface ExecutionContext

hasQueryExecutionToBeAddedToStatistics
