Method Detail

getValue

public AstNode getValue()
Returns yielded expression, null if none


setValue

public void setValue(AstNode expr)
Sets yielded expression, and sets its parent to this node.

Parameters:
expr - the value to yield. 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, and if present, the yielded value.

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