getCanonicalQueryLanguage
protected String getCanonicalQueryLanguage()
Description copied from class:JRAbstractQueryExecuter
Returns a canonical query language for this query executer implementation.The canonical language is used to retrieve extensions for the query executer.
The default implementation returns the runtime query language used in the dataset, but query executer implementations should override this method and return a fixed language.
- Overrides:
getCanonicalQueryLanguage
in classJRAbstractQueryExecuter
- Returns:
- a canonical query language
-
getParameterReplacement
protected String getParameterReplacement(String parameterName)
Description copied from class:JRAbstractQueryExecuter
Returns the replacement text for a query parameter.- Specified by:
getParameterReplacement
in classJRAbstractQueryExecuter
- Parameters:
parameterName
- the parameter name- Returns:
- the replacement text
