Constructor Details

SubroutineDestReferenceIterator

public SubroutineDestReferenceIterator(CodeBlock block,
 TaskMonitor monitor)
                                throws CancelledException

Construct an Iterator over Destination blocks for a CodeBlock. External references will be ignored.

Parameters:

block - block to get destination blocks for. This should be a subroutine obtained from PartitionCodeSubModel.

monitor - task monitor which allows user to cancel operation.

Throws:

CancelledException - if the monitor cancels the operation.
