Method Detail

isEmpty

public boolean isEmpty()

Overrides:

isEmpty in class Stmt

requireBlockStmt

public void requireBlockStmt()

Overrides:

requireBlockStmt in class Stmt

mustBeLive

public boolean mustBeLive()

when the -lenient option is used, we declare that empty block don't have to be live. This makes code like: return 2; {} legal.

Overrides:

mustBeLive in class Stmt

walkFlow

public void walkFlow(org.aspectj.compiler.base.FlowCheckerPass w)

Overrides:

walkFlow in class ASTObject

walkCleanup

public void walkCleanup(org.aspectj.compiler.base.ByteCodeCleanupPass w)

Overrides:

walkCleanup in class ASTObject

postCleanup

public ASTObject postCleanup(org.aspectj.compiler.base.ByteCodeCleanupPass w)

Overrides:

postCleanup in class ASTObject

makeTempsExplicit

protected void makeTempsExplicit()

walkFrameLoc

public void walkFrameLoc(org.aspectj.compiler.base.FrameLocPass walker)

Overrides:

walkFrameLoc in class ASTObject

preScope

public void preScope(ScopeWalker walker)

Overrides:

preScope in class ASTObject

postScope

public ASTObject postScope(ScopeWalker walker)

Overrides:

postScope in class ASTObject

makeTemporary

public VarDec makeTemporary(Type type)

addTemporary

public void addTemporary(VarDec tmp)

checkReturnType

public void checkReturnType(Type expectedReturnType)

unparse

public void unparse(org.aspectj.compiler.base.CodeWriter writer)

Specified by:

unparse in interface AspectMember

Overrides:

unparse in class ASTObject

cleanup

public void cleanup()

Specified by:

cleanup in interface AspectMember

Overrides:

cleanup in class ASTObject

cgStmt

protected void cgStmt(org.aspectj.compiler.base.bcg.CodeBuilder cb)

Description copied from class: Stmt

This procedure does the work of generating bytecode. Its main requirement is to leave the stack empty. This method should only be called from Stmt.cgTop(org.aspectj.compiler.base.bcg.CodeBuilder).

Overrides:

cgStmt in class Stmt

getTmpStmts

public Stmts getTmpStmts()

setTmpStmts

public void setTmpStmts(Stmts _tmpStmts)

getStmts

public Stmts getStmts()

setStmts

public void setStmts(Stmts _stmts)

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getChildAt

public ASTObject getChildAt(int childIndex)

Overrides:

getChildAt in class ASTObject

getChildNameAt

public java.lang.String getChildNameAt(int childIndex)

Overrides:

getChildNameAt in class ASTObject

setChildAt

public void setChildAt(int childIndex,
                       ASTObject child)

Overrides:

setChildAt in class ASTObject

getChildCount

public int getChildCount()

Overrides:

getChildCount in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class Stmt
