Interface IBasicBlock

All Known Implementing Classes:

Block

public interface IBasicBlock

IBasicBlock defines the minimum necessary semantics of a vertex in an AET method body's IFlowgraph.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	canFallThrough() Can this block's control fall through the end?
Instruction	get(int idx) Fetch the Instruction at the specified position.
List<Instruction>	getInstructions() Get the contents of the block.
Collection<? extends IBasicBlock>	getSuccessors() Get this block's successors; this defines the set of edges in the flowgraph.
int	size() How big is this block?

Method Detail

getSuccessors

Collection<? extends IBasicBlock> getSuccessors()

Get this block's successors; this defines the set of edges in the flowgraph.

Returns:

this block's successors in the control-flow graph.

getInstructions

List<Instruction> getInstructions()

Get the contents of the block.

Returns:

this block's instructions as a mutable List.

size

int size()

How big is this block?

Returns:

the size of getInstructions.size().

get

Instruction get(int idx)

Fetch the Instruction at the specified position.

Parameters:

idx - - the Instruction's position.

Returns:

the Instruction at that position.

canFallThrough

boolean canFallThrough()

Can this block's control fall through the end?

Returns:

true if the block doesn't unconditionally transfer control.
