    public class SwitchCase
    extends AstNode

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

    CaseBlock :
            { [CaseClauses] }
            { [CaseClauses] DefaultClause [CaseClauses] }
     CaseClauses :
            CaseClause
            CaseClauses CaseClause
     CaseClause :
            case Expression : [StatementList]
     DefaultClause :
            default : [StatementList]

### Constructor Detail

#### SwitchCase

    public SwitchCase()

#### SwitchCase

    public SwitchCase(int pos)

#### SwitchCase

    public SwitchCase(int pos,
              int len)

### Method Detail

#### getExpression

    public AstNode getExpression()

Returns the case expression, `null` for default case

#### setExpression

    public void setExpression(AstNode expression)

Sets the case 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`.

#### isDefault

    public boolean isDefault()

Return true if this is a default case.

Returns:
  true if `getExpression()` would return `null`

#### getStatements

    public java.util.List<AstNode> getStatements()

Returns statement list, which may be `null`.

#### setStatements

    public void setStatements(java.util.List<AstNode> statements)

Sets statement list. May be `null`. Replaces any existing statements. Each element in the list has its parent set to this node.

#### addStatement

    public void addStatement(AstNode statement)

Adds a statement to the end of the statement list. Sets the parent of the new statement to this node, updates its start offset to be relative to this node, and sets the length of this node to include the new child.

Parameters:
  `statement` - a child statement
Throws:
  `IllegalArgumentException}` - if statement is `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 case expression if present, then each statement (if any are specified).

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