Method Detail

createQuery

public IQuery createQuery()

Specified by:

createQuery in interface IDataSet

Returns:

See Also:

IDataSet.createQuery()

getAttributes

public java.util.Map<java.lang.String,IAttribute> getAttributes()

Specified by:

getAttributes in interface IDataSet

Returns:

See Also:

IDataSet.getAttributes()

addAttribute

public void addAttribute(IAttribute attribute)

Parameters:

attribute -

setAttributes

public void setAttributes(java.util.List<IAttribute> attributes)

Parameters:

attributes -

performDelete

public abstract long performDelete(java.util.List<ICondition> conditions)

Specified by:

performDelete in interface IDatabaseOperationPerformer

Returns:

See Also:

IDatabaseOperationPerformer.performDelete(java.util.List)

performInsert

public abstract void performInsert(java.util.Map<IAttribute,ICell> row)

Specified by:

performInsert in interface IDatabaseOperationPerformer

See Also:

IDatabaseOperationPerformer.performInsert(java.util.Map)

performInsert

public void performInsert(IData data)

Insert given data into data storage. This method simply calls performInsert(Map) for each row in data. Overriding classes may use some more effective approach depending on the type of used data storage (e.g. chunked SQL INSERT etc).

Specified by:

performInsert in interface IDatabaseOperationPerformer

Parameters:

data - data to be inserted into data storage

See Also:

IDatabaseOperationPerformer.performInsert(net.sf.webmancer.db.IData)

performQueryCount

public abstract long performQueryCount(java.util.List<ICondition> conditions)

Specified by:

performQueryCount in interface IDatabaseOperationPerformer

Returns:

See Also:

IDatabaseOperationPerformer.performQueryCount(java.util.List)

performQueryResult

public abstract IData performQueryResult(java.util.Map<java.lang.String,IAttribute> attributes,
                                         java.util.List<ICondition> conditions,
                                         long limit,
                                         long offset,
                                         IAttribute orderingAttribute,
                                         boolean ascending)

Specified by:

performQueryResult in interface IDatabaseOperationPerformer

Returns:

See Also:

IDatabaseOperationPerformer.performQueryResult(java.util.Map, java.util.List, long, long, net.sf.webmancer.db.IAttribute, boolean)
