public AstNode getInitializer()
VariableDeclaration

of
type COMMA that chains multiple variable assignments.
public void setInitializer(AstNode initializer)
null
-check.
initializer
- loop initializer. Pass an
EmptyExpression
if the initializer is not specified.
java.lang.IllegalArgumentException
- if condition is null
public AstNode getCondition()
public void setCondition(AstNode condition)
condition
- loop condition. Pass an EmptyExpression
if the condition is missing.
IllegalArgumentException}
- if condition is null
public AstNode getIncrement()
public void setIncrement(AstNode increment)
increment
- loop increment expression. Pass an
EmptyExpression
if increment is null
.
IllegalArgumentException}
- if increment is null
public java.lang.String toSource(int depth)
AstNode
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.
toSource
in class Scope
depth
- the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit
in class Scope
v
- the object to call with this node and its children
