createInputConnectorPoint

MapConnectorPoint createInputConnectorPoint(java.lang.String name)
                                     throws MappingException

Add an input connector point to this component. An input connector point represents a point through which an upstream component can be connected to this one. The connection represents data flow from one component to another. A set of projector attributes defines the shape of the data that flows from one component to another through connector points. If a single component has multiple input connector points, it means that the component supports processing of multiple upstream source data streams. Many components have input connector points added automatically by the delegate when the component is created, so it may not be necessary to explicitly add them later. That is, even though this is a "create" method, it may actually "reuse" an existing connector point that is unconnected. To force creation of a new connector point, even if existing CP's are unused, this can be done by passing the empty string "" as the name. If no input connector point can be created or found, returns null.

Parameters:

If null, a name will be autogenerated (e.g. "INPUT1"), and reuse of an unused existing connector point will be tried first. If "", a name will be autogenerated, and only creation of a new connector point will be tried.

createOutputConnectorPoint

MapConnectorPoint createOutputConnectorPoint()
                                      throws MappingException

Adds an output connector point to this component. An output connector point represents a point through which a downstream component can be connected to this one. The connection represents data flow from one component to another. A set of projector attributes defines the shape of the data that flows from one component to another through connector points. If a single component has multiple output connector points, it means that the component provides multiple data streams to downstream components. Many components have output connector points added automatically by the delegate when the component is created, so it may not be necessary to explicitly add them later. That is, even though this is a "create" method, it may actually "reuse" an existing connector point that is unconnected. The name of the output connector point will be autogenerated (e.g. "OUTPUT1"). If no output connector point can be created or found, returns null.

Returns:

The newly created output connector point, or an unused existing one, or null.

Throws:

oracle.odi.domain.mapping.exception.MapComponentException

PropertyException

MappingException

createOutputConnectorPoint

MapConnectorPoint createOutputConnectorPoint(java.lang.String name)
                                      throws MappingException

Adds an output connector point to this component. An output connector point represents a point through which a downstream component can be connected to this one. The connection represents data flow from one component to another. A set of projector attributes defines the shape of the data that flows from one component to another through connector points. If a single component has multiple output connector points, it means that the component provides multiple data streams to downstream components. Many components have output connector points added automatically by the delegate when the component is created, so it may not be necessary to explicitly add them later. That is, even though this is a "create" method, it may actually "reuse" an existing connector point that is unconnected. To force creation of a new connector point, even if existing CP's are unused, this can be done by passing the empty string "" as the name. If no output point can be created or found, returns null.

Parameters:

name - The name given to the newly created connector point, or to an unconnected existing connector point. If null, a name will be autogenerated (e.g. "OUTPUT1"), and reuse of an unused existing connector point will be tried first. If "", a name will be autogenerated, and only creation of a new connector point will be tried.

Returns:

The newly created output connector point, or an unused existing one, or null.
