public class QuerySerializer
extends Object

Note: Query serialization and deserialization does not work for all possible permutations of query parts at the moment. For instance, BooleanQuery will not work. You should not use the QuerySerializer in it's current guise.

Constructor Detail

QuerySerializer

public QuerySerializer(QueryFactory queryFactory)

Construct a new query serializer

Parameters:

queryFactory - the factory to convert SearchQuery string keys back into query objects

Method Detail

queryToString

public static String queryToString(SearchQuery query)

Convert a SearchQuery into a string form that can be transported over the wire, saved, and so on

Parameters:

query - the query to convert

Returns:

a string form of that query

stringToQuery

public SearchQuery stringToQuery(String s)
                          throws InvalidQueryException

Convert a string-form query back into object form. If the string is not a valid query an exception will be thrown. This will always be caused by one of two things: the string was generated incorrectly manually (i.e. not by the serializer), or some SearchQuery plugin that was used during query generation is no longer available.

All clients of the serializer must be able to recover from both of the above circumstances safely.

Parameters:

s - the string to convert

Returns:

the SearchQuery that corresponds to the string provided

Throws:

InvalidQueryException - if the string could not be converted successfully

escape

protected static String escape(String s)

Escape any double-quote in a string with a backslash, and any backslash with a second backslash.

Parameters:

s - the string to quote

Returns:

the escaped string
