processQuery

public CQLQueryResults processQuery(CQLQuery cqlQuery)
                             throws MalformedQueryException,
                                    QueryProcessingException

Description copied from class: CQLQueryProcessor

Processes the CQL Query

Specified by:

processQuery in class CQLQueryProcessor

Returns:

The results of processing a CQL query

Throws:

MalformedQueryException - Should be thrown when the query itself does not conform to the CQL standard or attempts to perform queries outside of the exposed domain model

QueryProcessingException - Thrown for all exceptions in query processing not related to the query being malformed

getRequiredParameters

public java.util.Properties getRequiredParameters()

Description copied from class: CQLQueryProcessor

Get a Properties object of parameters the query processor will require on initialization. Subclasses can override this method to return a map describing paramters their implementation needs. The keys are the names of parameters the query processor requires, the values are the defaults for those properties. The default value of a property may be an empty string if it is an optional paramter. The keys MUST be valid java variable names. They MUST NOT contain spaces or punctuation. They may begin with an uppercase character.

Overrides:

getRequiredParameters in class CQLQueryProcessor

Returns:

The required properties for the query processor with their default values
