  - ### getMethod

    public Expression getMethod()

  - ### setMethod

    public void setMethod(Expression method)

  - ### getMethodAsString

    public String getMethodAsString()
    This method returns the method name as String if it is no dynamic calculated method name, but a constant.
    Specified by:
      `getMethodAsString` in interface `MethodCall`

  - ### getObjectExpression

    public Expression getObjectExpression()

  - ### setObjectExpression

    public void setObjectExpression(Expression objectExpression)

    Specified by:
      `getText` in interface `MethodCall`
    Overrides:
      `getText` in class `ASTNode`

  - ### isSafe

    public boolean isSafe()
    Returns:
      is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

  - ### setSafe

    public void setSafe(boolean safe)

  - ### isSpreadSafe

    public boolean isSpreadSafe()

  - ### setSpreadSafe

    public void setSpreadSafe(boolean value)

  - ### isImplicitThis

    public boolean isImplicitThis()
    Returns:
      true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false

  - ### setImplicitThis

    public void setImplicitThis(boolean implicitThis)

    public MethodNode getMethodTarget()
    Returns:
      the target as method node if set

  - ### setMethodTarget

    public void setMethodTarget(MethodNode mn)
    Sets a method call target for a direct method call. WARNING: A method call made this way will run outside of the MOP!
    Parameters:
      `mn` - the target as MethodNode, mn==null means no target

  - ### setSourcePosition

    public void setSourcePosition(ASTNode node)
    Description copied from class: `ASTNode`
    Sets the source position using another ASTNode. The sourcePosition consists of a line/column pair for the start and a line/column pair for the end of the expression or statement
    Overrides:
      `setSourcePosition` in class `ASTNode`
    Parameters:
      `node` - - the node used to configure the position information
