JdbcExecutionContextDao

public JdbcExecutionContextDao()

Method Detail

setSerializer

public void setSerializer(ExecutionContextSerializer serializer)

Setter for Serializer implementation

Parameters:

serializer -

setShortContextLength

public void setShortContextLength(int shortContextLength)

The maximum size that an execution context can have and still be stored completely in short form in the column SHORT_CONTEXT. Anything longer than this will overflow into large-object storage, and the first part only will be retained in the short form for readability. Default value is 2500. Clients using multi-bytes charsets on the database server may need to reduce this value to as little as half the value of the column size.

Parameters:

shortContextLength -

getExecutionContext

public ExecutionContext getExecutionContext(JobExecution jobExecution)

Specified by:

getExecutionContext in interface ExecutionContextDao

Returns:

execution context associated with the given jobExecution

getExecutionContext

public ExecutionContext getExecutionContext(StepExecution stepExecution)

Specified by:

getExecutionContext in interface ExecutionContextDao

Returns:

execution context associated with the given stepExecution

updateExecutionContext

public void updateExecutionContext(JobExecution jobExecution)

Description copied from interface: ExecutionContextDao

Persist the updates of execution context associated with the given jobExecution. Persistent entry should already exist for this context.

Specified by:

updateExecutionContext in interface ExecutionContextDao

updateExecutionContext

public void updateExecutionContext(StepExecution stepExecution)

Description copied from interface: ExecutionContextDao

Persist the updates of execution context associated with the given stepExecution. Persistent entry should already exist for this context.

Specified by:

saveExecutionContext

public void saveExecutionContext(JobExecution jobExecution)

Description copied from interface: ExecutionContextDao

Persist the execution context associated with the given jobExecution, persistent entry for the context should not exist yet.

Specified by:

saveExecutionContext in interface ExecutionContextDao

saveExecutionContext

public void saveExecutionContext(StepExecution stepExecution)

Description copied from interface: ExecutionContextDao

saveExecutionContexts

public void saveExecutionContexts(Collection<StepExecution> stepExecutions)

Description copied from interface: ExecutionContextDao

Overrides:

afterPropertiesSet in class AbstractJdbcBatchMetadataDao

Throws:

Exception
