withAttributes

public StreamLayout.Module withAttributes(Attributes newAttr)

Specified by:

withAttributes in interface StreamLayout.Module

carbonCopy

public final StreamLayout.Module carbonCopy()

Description copied from interface: StreamLayout.Module

The purpose of this method is to create a copy to be included in a larger graph such that port identity clashes are avoided. Where a full copy is not possible or desirable, use a CopiedModule. The shape of the resulting module MUST NOT contain the same ports as this module’s shape.

Specified by:

carbonCopy in interface StreamLayout.Module

Returns:

(undocumented)

replaceShape

public final StreamLayout.Module replaceShape(Shape newShape)

Description copied from interface: StreamLayout.Module

Verify that the given Shape has the same ports and return a new module with that shape. Concrete implementations may throw UnsupportedOperationException where applicable.

Please note that this method MUST NOT be implemented using a CopiedModule since the purpose of replaceShape can also be to rearrange the ports (as in BidiFlow.reversed) and that purpose would be defeated.

Specified by:

replaceShape in interface StreamLayout.Module

Parameters:

newShape - (undocumented)

Returns:

(undocumented)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
