Class Query

java.lang.Object
  org.ascape.model.event.DefaultScapeListener
      org.ascape.query.Query

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.EventListener, ScapeListener, HasName

public class Query
extends DefaultScapeListener

Only the form-based searches have the option of being dynamic. By default, they are static searches. The dynamicSearch flag will change that. Searches by user-input cannot be dynamic, due to the current implementation.

Constructor Detail

Query

public Query(Scape collection,
             java.lang.String queryString)
      throws ParseException

TODO: All of this. Mostly, make searching the same, regardless of simple or complex quotes, especially re: the spacing between parameters. String based. See comments below for more details, but essentially, a search with a boolean operator (complex) must be enclosed by parens. Searches without one (simple) can be, but do not have to be. Complex Query: A series of strings using parens and boolean operators. For now, unlike the simple queries, there are no spaces allowed in the simple query portions. For example, ((age>15) AND (color=blue)). Complex queries do not yet allow for parameters enclosed in quotes. Simple Query: assume each token is a param_operator_value broken up by BooleanOperators example 1: age>15 example 2: color=blue.. Zero or One space is allowed. New Note: When a search parameter is enclosed in quotes ("Holland Queen"), you must leave a space between the parameters: value2 = "Holland Queen". take each token and parse it into a search string

Parameters:

collection - the collection to be searched

queryString -

Throws:

ParseException
