- All Implemented Interfaces:
CodeBlockReferenceIterator
public class SimpleDestReferenceIterator extends java.lang.Object implements CodeBlockReferenceIterator
This iterator is implemented by getting the flows from the instruction and iterating over those flows (plus the fallthrough). This is probably not the most efficient method. An linked-list of references has to be created each time we want to get the destinations from a block.

SimpleDestReferenceIterator
public SimpleDestReferenceIterator(CodeBlock block, boolean followIndirectFlows, TaskMonitor monitor) throws CancelledException
Construct an Iterator over Destination blocks for a CodeBlock. External references are ignored.- Parameters:
block
- block to get destination blocks for. This should be a block obtained from SimpleBlockModel.followIndirectFlows
- indirect references will only be included if truemonitor
- task monitor which allows user to cancel operation.- Throws:
CancelledException
- if the monitor cancels the operation.

hasNext
public boolean hasNext() throws CancelledException
Description copied from interface:CodeBlockReferenceIterator
Return true if next() will return a CodeBlockReference.- Specified by:

getNumDestinations
@Deprecated public static int getNumDestinations(CodeBlock block, boolean followIndirectFlows, TaskMonitor monitor) throws CancelledException
Deprecated.this method should be avoided since it repeats the work of the iteratorGet number of destination references flowing out of this block. All Calls from this block, and all external FlowType block references from this block are ignored.- Parameters:
block
- code block to get the number of destination references from.followIndirectFlows
- indirect references will only be included if truemonitor
- task monitor which allows user to cancel operation.- Throws:
CancelledException
- if the monitor cancels the operation.
