Class ArgumentParser<I,O>

java.lang.Object

com.hazelcast.query.extractor.ArgumentParser<I,O>

Type Parameters:

I - type of the unparsed argument object (input)

O - type of the parsed argument object (output)

Direct Known Subclasses:

DefaultArgumentParser

public abstract class ArgumentParser<I,O>
extends Object

Common superclass for all argument parsers.

For now, it's not possible to register a custom ArgumentParser, thus a default parser is used. It follows a "pass-through" semantics, which means that the string located in the square-brackets is passed "as-is" to the extract method.

It is not allowed to use square brackets within the argument string.
