Method Detail
-
setType
public KeywordLiteral setType(int nodeType)
Sets node token type
-
isBooleanLiteral
public boolean isBooleanLiteral()
Returns true if the token type isToken.TRUEorToken.FALSE.
-
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. There are no children to visit.
