Example 1 with RuleIElementType

use of org.antlr.jetbrains.adaptor.lexer.RuleIElementType in project ballerina by ballerina-lang.

the class IdentifierPSINode method getReference.

/**
 * Create and return a PsiReference object associated with this ID
 * node. The reference object will be asked to resolve this ref
 * by using the text of this node to identify the appropriate definition
 * site. The definition site is typically a subtree for a function
 * or variable definition whereas this reference is just to this ID
 * leaf node.
 * <p>
 * As the AST factory has no context and cannot create different kinds
 * of PsiNamedElement nodes according to context, every ID node
 * in the tree will be of this type. So, we distinguish references
 * from definitions or other uses by looking at context in this method
 * as we have parent (context) information.
