类 StatisticUpdaterDaoImpl

java.lang.Object

org.olat.data.course.statistic.StatisticUpdaterDaoImpl

所有已实现的接口:

StatisticUpdaterDao

public class StatisticUpdaterDaoImpl
extends java.lang.Object
implements StatisticUpdaterDao

Default implementation for IStatisticUpdater. Could be renamed into StatisticUpdaterDaoImpl.

This implementation takes the following properties (via spring):

• jdbcTemplate: the JdbcTemplate to be used to access the o_loggingtable and to create the o_stat_* tables - note that this might be different from the default database configured in OLAT when using a master-slave setup for example
• updateSQL: a list of (raw) sql statements which update the o_stat_* table (only the one to which this updater belongs!). The idea of these sql statements is to support incremental updates, i.e. to only update the difference, not having to delete the whole o_stat_* table away on each update (in order to improve speed)
• deleteSQL: a list of (raw) sql statements which delete the o_stat_* table (only the one to which this updater belongs!)

方法详细资料

setLoggingName

public void setLoggingName(java.lang.String loggingName)

set via spring

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

setJdbcTemplate

public void setJdbcTemplate(org.springframework.jdbc.core.JdbcTemplate jdbcTemplate)

set via spring

setUpdateSQL

public void setUpdateSQL(java.lang.String[] updateSQL)

set via spring

setDeleteSQL

public void setDeleteSQL(java.lang.String[] deleteSQL)

set via spring

updateStatistic

public final void updateStatistic(boolean fullRecalculation,
                   java.util.Date from,
                   java.util.Date until)

从接口复制的说明: StatisticUpdaterDao

Update the statistic table belonging to this implementor

指定者:

updateStatistic 在接口中 StatisticUpdaterDao

参数:

fullRecalculation - when set to true the statisticupdater should do a complete recalc of all stats, rather than updating since the last call to updateStatistic

from - update the statistics starting at the given from date - note that this is never null irrespective of fullRecalculation true or false

until - update the statistics ending at the given until date - this is never null
