getQueryParser

public QueryParser getQueryParser(ASG query)

Description copied from class: AutoMedWrapper

Return a parser that will accept queries for the wrapper. The default parser is Schemes, which accepts only single schemes, with no other IQL operators supported. The SimpleComp parser will allow simple list comprehensions to be passed to the wrapper.

Overrides:
