DOFJdbcPersistor

public DOFJdbcPersistor()

Method Details

initMaxQueryCount

public static void initMaxQueryCount(int value)

Sets the maximum number of data items that is read from the database.

getMaxQueryCount

public int getMaxQueryCount()

save

public void save(DOFObject instance)

Specified by:

save in interface IDOFObjectPersistor

remove

public void remove(DOFObject instance)

Specified by:

remove in interface IDOFObjectPersistor

init

public void init(String value)

Specified by:

init in interface IDOFObjectPersistor

executeQuery

public IDOFObjectPersistor.QueryResult executeQuery(DOFObjectType objectType,
 DOFObjectFilter filter)

Specified by:

executeQuery in interface IDOFObjectPersistor

buildPropertyFilterConditionString

protected String buildPropertyFilterConditionString(DOFObjectType objectType,
 DOFPropertyType pt,
 DOFObjectFilter filter,
 List<Object> queryValues)

Creates the SQL condition string for a property. The result is inserted in the whole query SQL statement that is built up in executeQuery(DOFObjectType, DOFObjectFilter).

Parameters:

queryValues - List of values that represents the values for the prepared statement. A prepared statement contains "?"-placeholder which then are popuplated by the list of objects. Do not directly insert values into the condition string in order to avoid SQL injection!

readDistinctValues

public Set<Object> readDistinctValues(DOFObjectType objectType,
 DOFPropertyType property)

Specified by:

readDistinctValues in interface IDOFObjectPersistor

updateConditionDuringExecuteQuery

protected String updateConditionDuringExecuteQuery(String condition)

updateSqlDuringReadDistinctValues

protected String updateSqlDuringReadDistinctValues(String sql)

updateSqlDuringRemove

protected String updateSqlDuringRemove(String sql)

updateSetListDuringUpdate

protected String updateSetListDuringUpdate(String set)

updateConditionDuringUpdate

protected String updateConditionDuringUpdate(String condition)

updateColumnsListDuringInsert

protected String updateColumnsListDuringInsert(String columnsList)

updateValuesListDuringInsert

protected String updateValuesListDuringInsert(String valuesList)

isAbleToPersistInstances

public boolean isAbleToPersistInstances()

Specified by:

isAbleToPersistInstances in interface IDOFObjectPersistor

isAbleToQuery

public boolean isAbleToQuery()

Specified by:

isAbleToQuery in interface IDOFObjectPersistor

isPermanent
