Method Detail

getReturnValue

public AstNode getReturnValue()

Returns return value, null if return value is void

setReturnValue

public void setReturnValue(AstNode returnValue)

Sets return value expression, and sets its parent to this node. Can be null.

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, then the return value if specified.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
