elements in interface CFG.IBlock<Tree>

Specified by:

elements in interface ControlFlowGraph.Block

trueBlock

public CFG.Block trueBlock()

falseBlock

public CFG.Block falseBlock()

exitBlock

public CFG.Block exitBlock()

isFinallyBlock

addExitSuccessor

public void addExitSuccessor(CFG.Block block)

predecessors

public Set<CFG.Block> predecessors()

successors

public Set<CFG.Block> successors()

Specified by:

successors in interface CFG.IBlock<Tree>

Specified by:

successors in interface ControlFlowGraph.Block

exceptions

public Set<CFG.Block> exceptions()

terminator

@CheckForNull
public Tree terminator()

Specified by:

terminator in interface CFG.IBlock<Tree>

Specified by:

terminator in interface ControlFlowGraph.Block

isInactive

public boolean isInactive()

isMethodExitBlock

public boolean isMethodExitBlock()

successorWithoutJump

@CheckForNull
public CFG.Block successorWithoutJump()

This method makes the implementation of RSPEC-3626 almost trivial.

Returns:

the block which would be the successor of this one if this one didn't terminate with a jump

caseGroup

@CheckForNull
public CaseGroupTree caseGroup()

Label is used to contain additional information about a block which is not directly related to CFG structure. Used for simplifying implementation of RSPEC-128.

setCaseGroup

public void setCaseGroup(CaseGroupTree caseGroup)
