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
