Constructor Detail

• public CompileStack(WriterController controller)

Method Detail

• public void addExceptionBlock(org.objectweb.asm.Label start, org.objectweb.asm.Label end, org.objectweb.asm.Label goal, String sig)

• public void applyBlockRecorder()

• public void applyFinallyBlocks(org.objectweb.asm.Label label, boolean isBreakLabel)

• public void clear()

  Clears the state of the class. This method should be called after a MethodNode is visited. Note that a call to init will fail if clear is not called before

• public boolean containsVariable(String name)

  Parameters:

  name - the name of the variable of interest

  Returns:

  true if a variable is already defined

• public org.objectweb.asm.Label createLocalLabel(String name)

  Creates or returns the label for the given name.

• public int defineTemporaryVariable(Variable var, boolean store)

  Creates a temporary variable.

  Parameters:

  var - specifies name and type

  store - defines if the toplevel argument of the stack should be stored

  Returns:

  the index used for this temporary variable

• public int defineTemporaryVariable(String name, boolean store)

  Creates a temporary variable.

  Parameters:

  name - defines type and name

  store - defines if the top-level argument of the stack should be stored

  Returns:

  the index used for this temporary variable

• public int defineTemporaryVariable(String name, ClassNode type, boolean store)

  Creates a temporary variable.

  Parameters:

  name - the variable name

  type - the variable type

  store - indicates if the top-level argument of the stack should be stored

  Returns:

  the index used for this temporary variable

• public BytecodeVariable defineVariable(Variable v, boolean initFromStack)

  Defines a new Variable using an AST variable.

  Parameters:

  initFromStack - if true the last element of the stack will be used to initialize the new variable. If false null will be used.

• public BytecodeVariable defineVariable(Variable v, ClassNode variableType, boolean initFromStack)

• public org.objectweb.asm.Label getBreakLabel()

• public org.objectweb.asm.Label getContinueLabel()

• public org.objectweb.asm.Label getLabel(String name)

  Returns the label for the given name.

• public org.objectweb.asm.Label getNamedBreakLabel(String name)

  Returns:

  the break label for name

• public org.objectweb.asm.Label getNamedContinueLabel(String name)

  Returns:

  the continue label for name

• public VariableScope getScope()

• public BytecodeVariable getVariable(String variableName)

• public BytecodeVariable getVariable(String variableName, boolean mustExist)

  Returns a normal variable.

  If mustExist is true and the normal variable doesn't exist, then this method will throw a GroovyBugError. It is not the intention of this method to let this happen! And the exception should not be used for flow control - it is just acting as an assertion. If the exception is thrown then it indicates a bug in the class using CompileStack. This method can also not be used to return a temporary variable. Temporary variables are not normal variables.

  Parameters:

  variableName - name of the variable

  mustExist - throw exception if variable does not exist

  Returns:

  the normal variable or null if not found (and mustExist not true)

• public boolean hasBlockRecorder()

• public void init(VariableScope scope, Parameter[] parameters)

  initializes this class for a MethodNode. This method will automatically define variables for the method parameters and will create references if needed. The created variables can be accessed by calling getVariable().

• public boolean isImplicitThis()

• public boolean isInSpecialConstructorCall()

• public boolean isLHS()

• public void pop()

• public void popBlockRecorderVisit(CompileStack.BlockRecorder finallyBlock)

• public void popImplicitThis()

• public void popLHS()

• public void pushBlockRecorder(CompileStack.BlockRecorder recorder)

• public void pushBlockRecorderVisit(CompileStack.BlockRecorder finallyBlock)

• @Deprecated(since = "5.0.0")
  public void pushBooleanExpression()

  Because a boolean Expression may not be evaluated completely it is important to keep the registers clean.

  deprecated:

  Use pushState() directly.

• public org.objectweb.asm.Label pushBreakable(List<String> labelNames)

  Creates a new break label and an element for the state stack so pop has to be called later.

  Returns:

  the break label

• public void pushImplicitThis(boolean implicitThis)

• public void pushInSpecialConstructorCall()

• public void pushLHS(boolean lhs)

• public void pushLoop(VariableScope scope, List<String> labelNames)

  Should be called when descending into a loop that defines also a scope. Calls pushVariableScope and prepares labels for a loop structure. Creates an element for the state stack so pop has to be called later

• @Deprecated(since = "6.0.0")
  public void pushLoop(VariableScope scope, String labelName)

  Should be called when descending into a loop that defines also a scope. Calls pushVariableScope and prepares labels for a loop structure. Creates a element for the state stack so pop has to be called later.

• public void pushLoop(List<String> labelNames)

  Should be called when descending into a loop that does not define a scope Creates a element for the state stack so pop has to be called later.

• @Deprecated(since = "6.0.0")
  public void pushLoop(String labelName)

  Should be called when descending into a loop that does not define a scope. Creates a element for the state stack so pop has to be called later.

• public void pushState()

• public org.objectweb.asm.Label pushSwitch()

  Creates a new break label and an element for the state stack so pop has to be called later.

  Returns:

  the break label

• public void pushVariableScope(VariableScope scope)

  Causes the state-stack to add an element and sets the given scope as new current variable scope. Creates an element for the state stack so pop has to be called later

• public void removeVar(int variableIndex)

  Indicates that the specified temporary variable is no longer used.

• public void writeExceptionTable(CompileStack.BlockRecorder block, org.objectweb.asm.Label goal, String sig)
