AbstractDataSetDefBuilder

public AbstractDataSetDefBuilder()

Method Detail

createDataSetDef

protected abstract DataSetDef createDataSetDef()

uuid

public T uuid(String uuid)

Description copied from interface: DataSetDefBuilder

Set the DataSetDef UUID.

Specified by:

uuid in interface DataSetDefBuilder<T>

Parameters:

uuid - The UUID of the DataSetDef that is being assembled.

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

name

public T name(String name)

Description copied from interface: DataSetDefBuilder

Set the DataSetDef name.

Specified by:

name in interface DataSetDefBuilder<T>

Parameters:

name - The name of the DataSetDef that is being assembled.

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

pushOn

public T pushOn(int pushMaxSize)

Description copied from interface: DataSetDefBuilder

Enable the ability to push remote data sets from server.

Specified by:

pushOn in interface DataSetDefBuilder<T>

Parameters:

pushMaxSize - The maximum size (in kbytes) a data set may have in order to be pushed to clients.

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

pushOff

public T pushOff()

Description copied from interface: DataSetDefBuilder

Disable the ability to push remote data sets from server.

Specified by:

pushOff in interface DataSetDefBuilder<T>

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

cacheOn

public T cacheOn(int maxRowsInCache)

Description copied from interface: DataSetDefBuilder

Enables the cache for this data set

Specified by:

cacheOn in interface DataSetDefBuilder<T>

Parameters:

maxRowsInCache - Max. rows the cache is able to handle. For higher values the cache is automatically disabled.

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

cacheOff

public T cacheOff()

Description copied from interface: DataSetDefBuilder

Disables the cache

Specified by:

cacheOff in interface DataSetDefBuilder<T>

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

refreshOn

public T refreshOn(String refreshTime,
                   boolean refreshAlways)

Description copied from interface: DataSetDefBuilder

Turns on the data set refresh mechanism. Every time the refresh time is met the data set will be forced to refresh. Any cache on the data set will be considered stale from that time on.

Specified by:

refreshOn in interface DataSetDefBuilder<T>

Parameters:

refreshTime - The amount of time between refresh intervals TimeAmount

refreshAlways - If false then the refresh will be only performed when the underlying data provider determines that the data set has become stale. Otherwise the data set is always refreshed. data set is outdated. This can be very useful to avoid refreshing unnecessarily.

Returns:

The DataSetDefBuilder instance that is being used to configure a DataSetDef.

refreshOff

public T refreshOff()

Description copied from interface: DataSetDefBuilder

Turns of the data set refresh mechanism.

Specified by:

refreshOff in interface DataSetDefBuilder<T>
