Constructor Detail

### FunctionCall

    public FunctionCall()

### FunctionCall

    public FunctionCall(int pos)

### FunctionCall

    public FunctionCall(int pos,
                        int len)

Method Detail

### getTarget

    public AstNode getTarget()

  Returns node evaluating to the function to call

### setTarget

    public void setTarget(AstNode target)

  Sets node evaluating to the function to call, and sets its parent to this node.

  Parameters:
    `target` - node evaluating to the function to call.
  Throws:
    `IllegalArgumentException}` - if target is `null`

### getArguments

    public java.util.List<AstNode> getArguments()

  Returns function argument list

  Returns:
    function argument list, or an empty immutable list if there are no arguments.

### setArguments

    public void setArguments(java.util.List<AstNode> arguments)

  Sets function argument list

  Parameters:
    `arguments` - function argument list. Can be `null`, in which case any existing args are removed.

### addArgument

    public void addArgument(AstNode arg)

  Adds an argument to the list, and sets its parent to this node.

  Parameters:
    `arg` - the argument node to add to the list
  Throws:
    `IllegalArgumentException}` - if arg is `null`

### getLp

    public int getLp()

  Returns left paren position, -1 if missing

### setLp

    public void setLp(int lp)

  Sets left paren position

  Parameters:
    `lp` - left paren position

### getRp

    public int getRp()

  Returns right paren position, -1 if missing

### setRp

    public void setRp(int rp)

  Sets right paren position

### setParens

    public void setParens(int lp,
                          int rp)

  Sets both paren positions

### toSource

    public java.lang.String toSource(int depth)

  Description copied from class: `AstNode`
  Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

  Note: if the parser was in error-recovery mode, some AST nodes may have `null` children that are expected to be non-`null` when no errors are present. In this situation, the behavior of the `toSource` method is undefined: `toSource` implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

  Specified by:
    `toSource` in class `AstNode`
  Parameters:
    `depth` - the current recursion depth, typically beginning at 0 when called on the root node.

### visit

    public void visit(NodeVisitor v)

  Visits this node, the target object, and the arguments.

  Specified by:
    `visit` in class `AstNode`
  Parameters:
    `v` - the object to call with this node and its children
