  • getMaxValue

    public int getMaxValue()

  • getNumCases

    public int getNumCases()

  • switchValuePushed

    public void switchValuePushed(CodeAttr code)

    Needs to be called after the switch value has been pushed. I.e. in execution order, just before the actual switch instruction. Called implicitly by CodeAttr.startSwitch().

  • addCase

    public boolean addCase(int value,
     CodeAttr code)

    Add a new case.

    Parameters:

    value - the case value to match against at run-time

    code - the CodeAttr of the Method we are generating code for

    Returns:

    true on success; false if value duplicates an existing value

  • addCaseGoto

    public boolean addCaseGoto(int value,
     CodeAttr code,
     Label label)

    Optimization of addCase(value, code); emitGoto(label).

  • addDefault

    public void addDefault(CodeAttr code)

  • insertCase

    public boolean insertCase(int value,
     Label label,
     CodeAttr code)

    Internal routine to add a new case.

    Parameters:

    value - the case value to match against at run-time

    label - the location to go to if the value matches

    code - the CodeAttr of the Method we are generating code for

    Returns:

    true on success; false if value duplicates an existing value

  • exitSwitch

    public void exitSwitch(CodeAttr code)

    Break/exit from this switch. Doesn't allow exiting through a try - if you need that, use an ExitableBlock.

  • finish

    public void finish(CodeAttr code)

    Handle the end of the switch statement. Assume the case value is on the stack; go to the matching case label.
