Constructor Details

ExtCodeBlockImpl

public ExtCodeBlockImpl(CodeBlockModel model,
 Address extAddr)

Method Details

getFirstStartAddress

public Address getFirstStartAddress()

Description copied from interface: CodeBlock

Return the first start address of the CodeBlock. Depending on the model used to generate the CodeBlock, there may be multiple entry points to the block. This will return the first start address for the block. It should always return the same address for a given block if there is more than one entry point.

Specified by:

getFirstStartAddress in interface CodeBlock

Returns:

the first start address of the block.

getFlowType

public FlowType getFlowType()

Description copied from interface: CodeBlock

Return, in theory, how things flow out of this node. If there are any abnormal ways to flow out of this node, (ie: jump, call, etc...) then the flow type of the node takes on that type. If there are multiple unique ways out of the node, then we should return FlowType.UNKNOWN. Fallthrough is returned if that is the only way out.

Specified by:

getFlowType in interface CodeBlock

Returns:

flow type of this node

getModel

public CodeBlockModel getModel()

Description copied from interface: CodeBlock

Get the model instance which was used to generate this block.

Specified by:

getModel in interface CodeBlock

Returns:

the model used to build this CodeBlock

getName

public String getName()

Description copied from interface: CodeBlock

Return the name of the block.

Specified by:

getName in interface CodeBlock

Returns:

name of block, normally the symbol at the starting address

getNumDestinations

public int getNumDestinations(TaskMonitor monitor)
                       throws CancelledException

Description copied from interface: CodeBlock

Get the number of CodeBlocks this block flows to. Note that this is almost as much work as getting the actual destination references.

Specified by:

getNumDestinations in interface CodeBlock

Parameters:

monitor - task monitor which allows user to cancel operation.

Returns:

number of destination CodeBlocks.

Throws:

CancelledException - if the monitor cancels the operation.

See Also:

• CodeBlock.getDestinations(ghidra.util.task.TaskMonitor)

getDestinations

public CodeBlockReferenceIterator getDestinations(TaskMonitor monitor)
                                           throws CancelledException

Description copied from interface: CodeBlock

Get an Iterator over the CodeBlocks that are flowed to from this CodeBlock.

Specified by:

getDestinations in interface CodeBlock

Parameters:

monitor - task monitor which allows user to cancel operation.

Returns:

An iterator over CodeBlocks referred to by this Block.

Throws:

CancelledException - if the monitor cancels the operation.

getNumSources

public int getNumSources(TaskMonitor monitor)
                  throws CancelledException

Description copied from interface: CodeBlock

Get the number of CodeBlocks that flow into this CodeBlock. Note that this is almost as much work as getting the actual source references.

Specified by:

getNumSources in interface CodeBlock

Parameters:

monitor - task monitor which allows user to cancel operation.

Returns:

number of source CodeBlocks.

Throws:

CancelledException - if the monitor cancels the operation.

See Also:

• CodeBlock.getSources(ghidra.util.task.TaskMonitor)

getSources

public CodeBlockReferenceIterator getSources(TaskMonitor monitor)
                                      throws CancelledException

Description copied from interface: CodeBlock

Get an Iterator over the CodeBlocks that flow into this CodeBlock.

Specified by:

getSources in interface CodeBlock

Parameters:

monitor - task monitor which allows user to cancel operation.

Returns:

An iterator over CodeBlocks referencing this Block.

Throws:

CancelledException - if the monitor cancels the operation.

getStartAddresses

public Address[] getStartAddresses()

Description copied from interface: CodeBlock

Get all the entry points to this block. Depending on the model, there may be more than one entry point. Entry points will be returned in natural sorted order.

Specified by:

getStartAddresses in interface CodeBlock

Returns:

an array of entry points to this block. a zero length array if there are no entry points.

hashCode

public int hashCode()

Overrides:

hashCode in class AddressSet

• Object.hashCode()
