Constructor Detail

ExceptionBlockImpl

public ExceptionBlockImpl()

Create an empty exceptional block.

Method Detail

setNode

public void setNode(Node c)

Set the node.

getNode

public Node getNode()

Description copied from interface: ExceptionBlock

Returns the node of this block.

Specified by:

getNode in interface ExceptionBlock

Returns:

the node of this block

getNodes

public List<Node> getNodes()

Returns the nodes contained within this basic block. The list may be empty.

The following invariant holds.

 forall n in getNodes() :: n.getBlock() == this

Description copied from interface: Block

Returns the last node of this block, or null if none.

Specified by:

getLastNode in interface Block

Returns:

the last node of this block or null

addExceptionalSuccessor

public void addExceptionalSuccessor(BlockImpl b,
                                    TypeMirror cause)

Add an exceptional successor.

Parameters:

b - the successor

cause - the exception type that leads to the given block

getExceptionalSuccessors

public Map<TypeMirror,Set<Block>> getExceptionalSuccessors()

Description copied from interface: ExceptionBlock

Returns the list of exceptional successor blocks as an unmodifiable map.

Specified by:

getExceptionalSuccessors in interface ExceptionBlock

Returns:

the list of exceptional successor blocks as an unmodifiable map

getSuccessors

public Set<Block> getSuccessors()

Description copied from interface: Block

Returns the successors of this basic block.
