public class SwitchCase
Switch-case AST node type. The switch case is always part of a
switch statement.
Node type is Token.CASE
.

public AstNode getExpression()
null
for default case
public void setExpression(AstNode expression)
null
for default case.
Note that for empty fall-through cases, they still have
a case expression. In case 0: case 1: break;
the
first case has an expression
that is a
NumberLiteral
with value 0
.
public boolean isDefault()
getExpression()
would return null
public java.util.List<AstNode> getStatements()
null
.
public void setStatements(java.util.List<AstNode> statements)
null
. Replaces any existing
statements. Each element in the list has its parent set to this node.
public void addStatement(AstNode statement)
statement
- a child statement
IllegalArgumentException}
- if statement 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 AstNode
depth
- the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit
in class AstNode
v
- the object to call with this node and its children
