Constructor Detail

SwitchStatement

public SwitchStatement()

SwitchStatement

public SwitchStatement(int pos)

SwitchStatement

public SwitchStatement(int pos,
                       int len)
Method Detail

getExpression

public AstNode getExpression()
Returns the switch discriminant expression


setExpression

public void setExpression(AstNode expression)
Sets the switch discriminant expression, and sets its parent to this node.

Throws:
IllegalArgumentException} - if expression is null

getCases

public java.util.List<SwitchCase> getCases()
Returns case statement list. If there are no cases, returns an immutable empty list.


setCases

public void setCases(java.util.List<SwitchCase> cases)
Sets case statement list, and sets the parent of each child case to this node.

Parameters:
cases - list, which may be null to remove all the cases

addCase

public void addCase(SwitchCase switchCase)
Adds a switch case statement to the end of the list.

Throws:
IllegalArgumentException} - if switchCase is null

getLp

public int getLp()
Returns left paren position, -1 if missing


setLp

public void setLp(int lp)
Sets left paren position


getRp

public int getRp()
Returns right paren position, -1 if missing


setRp

public void setRp(int rp)
Sets right paren position


setParens

public void setParens(int lp,
                      int rp)
Sets both paren positions


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.

Overrides:
toSource in class Jump
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 switch-expression, then the cases in lexical order.

Overrides:
visit in class Jump
Parameters:
v - the object to call with this node and its children
