Class CFGBuilder.ExtendedNode

java.lang.Object

org.checkerframework.dataflow.cfg.CFGBuilder.ExtendedNode

Direct Known Subclasses:

CFGBuilder.ConditionalJump, CFGBuilder.NodeHolder, CFGBuilder.NodeWithExceptionsHolder, CFGBuilder.UnconditionalJump

Enclosing class:

CFGBuilder

protected abstract static class CFGBuilder.ExtendedNode
extends Object

An extended node can be one of several things (depending on its type):

• NODE. An extended node of this type is just a wrapper for a Node (that cannot throw exceptions).
• EXCEPTION_NODE. A wrapper for a Node which can throw exceptions. It contains a label for every possible exception type the node might throw.
• UNCONDITIONAL_JUMP. An unconditional jump to a label.
• TWO_TARGET_CONDITIONAL_JUMP. A conditional jump with two targets for both the 'then' and 'else' branch.
