public class AcopDataSourceJoint
extends AcopTransportDataSource
implements DataSourceJoint<AcopTransportDataSource>

AcopDataSourceJoint is an implementation of DataSourceJoint which combines several AcopTransportDataSource. DataSources are combined in the manner prescribed by the DataSourceJoint API.

AcopDataSourceJoint supports only com.cosylabu.gui.displayers.DoubleSeqConsumer

Method Summary

void	addConsumer(DataConsumer consumer) This support implementation does not perform any type check on consumer, it just adds it to list of consumers.
void	addDataSource(AcopTransportDataSource dataSource, java.lang.String operation) Adds a DataSource to the chain of source as the last dataSource.
void	addDataSource(AcopTransportDataSource dataSource, java.lang.String operation, int index) Adds a DataSource to the chain of source at the position specified by index.
java.util.Map<AcopTransportDataSource,java.lang.String>	getDataSources() Returns a Map of all dataSources and their identifiers.
java.lang.String	removeDataSource(AcopTransportDataSource dataSource) Removes the dataSource from this joint.

Constructor Detail

AcopDataSourceJoint

public AcopDataSourceJoint()

Constructs a new AcopDataSOurceJoint object.

Method Detail

getDataSources

public java.util.Map<AcopTransportDataSource,java.lang.String> getDataSources()

Description copied from interface: DataSourceJoint

Returns a Map of all dataSources and their identifiers. The map is expected to use data sources as keys and operation identifiers as values. The order of data sources should be preserved.

Specified by:

getDataSources in interface DataSourceJoint<AcopTransportDataSource>

Returns:

a map of all data sources

removeDataSource

public java.lang.String removeDataSource(AcopTransportDataSource dataSource)

Description copied from interface: DataSourceJoint

Removes the dataSource from this joint. When a single DataSource is removed, it should not have any effects on the complete chain of sources. The sources that are further down in the chain should be moves upward. Method should return identifier of the operation associated with the removed data source.

Specified by:

removeDataSource in interface DataSourceJoint<AcopTransportDataSource>

Parameters:

dataSource - DataSource to be removed

Returns:

operation associated with the data source

addDataSource

public void addDataSource(AcopTransportDataSource dataSource,
                          java.lang.String operation)
                   throws java.beans.PropertyVetoException

Description copied from interface: DataSourceJoint

Adds a DataSource to the chain of source as the last dataSource. The operation between added DataSource and the existing chain is specified by operation parameter, which can be one of the public identifiers.

Specified by:

addDataSource in interface DataSourceJoint<AcopTransportDataSource>

Throws:

java.beans.PropertyVetoException

addDataSource

public void addDataSource(AcopTransportDataSource dataSource,
                          java.lang.String operation,
                          int index)
                   throws java.beans.PropertyVetoException

Description copied from interface: DataSourceJoint

Adds a DataSource to the chain of source at the position specified by index. The operation between added DataSource and the existing chain is specified by operation parameter, which can be one of the public identifiers. The FIRST_IN_A_ROW is specified by index 0. If a DataSource is added as first in a row it would replace the existing first DataSource and its identifier should be automatically changed to FIRST_IN_A_ROW if a different one is given.

Specified by:

addDataSource in interface DataSourceJoint<AcopTransportDataSource>

Throws:

java.beans.PropertyVetoException

addConsumer

public void addConsumer(DataConsumer consumer)
                 throws java.beans.PropertyVetoException

Description copied from class: DataSourceSupport

This support implementation does not perform any type check on consumer, it just adds it to list of consumers.

Specified by:

addConsumer in interface DataSource

Overrides:

addConsumer in class AcopTransportDataSource

Parameters:

consumer - the data consumer to be regitered at this data source

Throws:

java.beans.PropertyVetoException
