Method Detail

getParentContextOfType
```
public static org.antlr.v4.runtime.ParserRuleContext getParentContextOfType(org.antlr.v4.runtime.ParserRuleContext currentContext,
                                                                            Class<?>... parentContextTypes)
```
Examines the parent rule contexts of the given context, and returns the first parent context which is assignable from (i.e. is a, or is a subclass of) one of the given context types.

Parameters:

currentContext - The starting context whose parent contexts should be examined

parentContextTypes - The types of parent context sought

Returns:

The first parent context which is assignable from one of the given context types, or null if there is no such parent in the tree

validateObjectTypeParameter

public static void validateObjectTypeParameter(Class<?> expectedType,
                                               String actualType)

validateExpectedNumberOfChildQueries

public static void validateExpectedNumberOfChildQueries(int expected,
                                                        int actual)

validateAllQueriesParsed

public static void validateAllQueriesParsed(int numQueriesEncountered,
                                            int numQueriesParsed)
