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
