Method Detail
-
getExpression
public AstNode getExpression()
Returns the case expression,nullfor default case
-
setExpression
public void setExpression(AstNode expression)
Sets the case expression,nullfor default case. Note that for empty fall-through cases, they still have a case expression. Incase 0: case 1: break;the first case has anexpressionthat is aNumberLiteralwith value0.
-
isDefault
public boolean isDefault()
Return true if this is a default case.- Returns:
- true if
getExpression()would returnnull
-
getStatements
public java.util.List<AstNode> getStatements()
Returns statement list, which may benull.
-
setStatements
public void setStatements(java.util.List<AstNode> statements)
Sets statement list. May benull. 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:
java.lang.IllegalArgumentException- } if statement isnull
-
toSource
public java.lang.String toSource(int depth)
Description copied from class:AstNodeEmits 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
nullchildren that are expected to be non-nullwhen no errors are present. In this situation, the behavior of thetoSourcemethod is undefined:toSourceimplementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.
-
visit
public void visit(NodeVisitor v)
Visits this node, then the case expression if present, then each statement (if any are specified).
