Constructor Details

SubroutineSourceReferenceIterator

public SubroutineSourceReferenceIterator(CodeBlock block,
 TaskMonitor monitor)
                                  throws CancelledException

Construct an Iterator over Source blocks for a CodeBlock.

Parameters:

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

monitor - task monitor which allows user to cancel operation.

Throws:

CancelledException - if the monitor cancels the operation.

Method Details

next

public CodeBlockReference next()
                        throws CancelledException

Description copied from interface: CodeBlockReferenceIterator

Return the next CodeBlockReference.

Specified by:

next in interface CodeBlockReferenceIterator

Throws:

CancelledException - thrown if the operation is cancelled.

• CodeBlockReferenceIterator.next()

hasNext

public boolean hasNext()
                throws CancelledException

Description copied from interface: CodeBlockReferenceIterator

Return true if next() will return a CodeBlockReference.

Specified by:

hasNext in interface CodeBlockReferenceIterator

Throws:

CancelledException - thrown if the operation is cancelled.

See Also:

• CodeBlockReferenceIterator.hasNext()

getNumSources

public static int getNumSources(CodeBlock block,
 TaskMonitor monitor)
                         throws CancelledException

Get number of source references flowing from this subroutine (block). All Calls to this block, and all external FlowType block references to this block are counted.

Parameters:

block - code block to get the number of source references to.

monitor - task monitor which allows user to cancel operation.

Throws:

CancelledException - if the monitor cancels the operation.
