Method Detail

mustBeLive

public boolean mustBeLive()

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

Overrides:

mustBeLive in class Stmt

unparse

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

Overrides:

unparse 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

copyWalk

public ASTObject copyWalk(CopyWalker walker)

Overrides:

copyWalk in class ASTObject

getDefaultDisplayName

public java.lang.String getDefaultDisplayName()

Overrides:

getDefaultDisplayName in class Stmt
