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

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

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

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()

Description copied from interface: RowProcessingState

Callback at the end of processing the current "row"

Specified by:

finishRowProcessing in interface RowProcessingState

resolveInitializer

public Initializer resolveInitializer(NavigablePath path)

Description copied from interface: RowProcessingState

Locate the Initializer registered for the given path

Specified by:

resolveInitializer in interface RowProcessingState

getQueryOptions

public QueryOptions getQueryOptions()

Specified by:

getQueryOptions in interface ExecutionContext

Overrides:

getQueryOptions in class BaseExecutionContext

getQueryParameterBindings

public QueryParameterBindings getQueryParameterBindings()

Specified by:

getQueryParameterBindings in interface ExecutionContext

Overrides:

Overrides:

getCallback in class BaseExecutionContext

hasCallbackActions

public boolean hasCallbackActions()

Specified by:

hasCallbackActions in interface ExecutionContext

getCollectionKey

public CollectionKey getCollectionKey()

Description copied from interface: ExecutionContext

Get the collection key for the collection which is to be loaded immediately.

Specified by:

getCollectionKey in interface ExecutionContext

getEntityInstance

public Object getEntityInstance()

Description copied from interface: ExecutionContext

Should only be used when initializing a bytecode-proxy

Specified by:

registerLoadingEntityEntry

public void registerLoadingEntityEntry(EntityKey entityKey,
                                       LoadingEntityEntry entry)

Specified by:

registerLoadingEntityEntry in interface ExecutionContext

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 todo (6.0) : come back and make sure we are calling this at appropriate times. despite the name, it should be called after a logical group of statements - e.g., after all of the delete statements against all of the tables for a particular entity

Specified by:

afterStatement in interface ExecutionContext

hasQueryExecutionToBeAddedToStatistics

public boolean hasQueryExecutionToBeAddedToStatistics()

Description copied from interface: ExecutionContext

Determine if the query execution has to be considered by the Statistics.

Specified by:

hasQueryExecutionToBeAddedToStatistics in interface ExecutionContext

Returns:

true if the query execution has to be added to the Statistics, false otherwise.
