CLASS_PROPERTY

Constructor Summary

protected	LQLQueryConfig()
	LQLQueryConfig(com.endeca.mdex.lql_parser.types.Query lqlQuery) Construct a new LQLQueryConfig with a specified query in the pre-parsed ast format.
	LQLQueryConfig(java.lang.String id, com.endeca.mdex.lql_parser.types.Query lqlQuery) Construct a new LQLQueryConfig with a specified query in pre-parsed ast format.

Method Summary

void	applyToDiscoveryServiceQuery(com.endeca.mdex.conversation.Request request) Apply this function to a Request.
com.endeca.mdex.lql_parser.types.Query	getQuery() gets the LQL expression in object form
java.lang.String	getQueryString() Returns an XML representation of this query's LQL AST.
void	setQuery(com.endeca.mdex.lql_parser.types.Query lqlQuery) sets the LQL query from an object form.
void	setQueryString(java.lang.String queryString) Sets this query's LQL AST expression from an XML representation.
java.lang.String	toString() This class' toString is abstract: all concrete subclasses are expected to provide an implementation. toString is used in comparing QueryFunction instances for equality, so if you implement a QueryFunction subclass it is important that your toString implementation be consistent and deterministic.

LQLQueryConfig

protected LQLQueryConfig()

LQLQueryConfig

public LQLQueryConfig(com.endeca.mdex.lql_parser.types.Query lqlQuery)

Construct a new LQLQueryConfig with a specified query in the pre-parsed ast format.

Parameters:

lqlQuery -

LQLQueryConfig

public LQLQueryConfig(java.lang.String id,
                      com.endeca.mdex.lql_parser.types.Query lqlQuery)

Construct a new LQLQueryConfig with a specified query in pre-parsed ast format.

Parameters:

id - A string id used to distinguish this function from others

lqlQuery -

Method Detail

getQuery

public com.endeca.mdex.lql_parser.types.Query getQuery()

gets the LQL expression in object form

Returns:

the LQL expression in object form

setQuery

public void setQuery(com.endeca.mdex.lql_parser.types.Query lqlQuery)

sets the LQL query from an object form.

Parameters:

lqlQuery - the LQL query in object form

getQueryString

public java.lang.String getQueryString()

Returns an XML representation of this query's LQL AST. This representation was previously created via LQLUtils.queryToString(Query).

Returns:

XML representation of the LQL AST

setQueryString

public void setQueryString(java.lang.String queryString)

Sets this query's LQL AST expression from an XML representation. To set the query directly from an object, see setQuery(Query). The XML input should have previously been generated by getQueryString() or LQLUtils.queryToString(Query). We recommend that users do not call this method directly. This method exists is required for deserialization of QueryState objects.

Parameters:

queryString - XML representation of the expression

applyToDiscoveryServiceQuery

public void applyToDiscoveryServiceQuery(com.endeca.mdex.conversation.Request request)
                                  throws QueryFunctionUnsupportedException

Description copied from class: QueryFunction

Apply this function to a Request. Must be implemented by subclass.

Specified by:

applyToDiscoveryServiceQuery in class QueryFunction

Throws:

QueryFunctionUnsupportedException

toString

public java.lang.String toString()

Description copied from class: QueryFunction

This class' toString is abstract: all concrete subclasses are expected to provide an implementation. toString is used in comparing QueryFunction instances for equality, so if you implement a QueryFunction subclass it is important that your toString implementation be consistent and deterministic.

Specified by:

toString in class QueryFunction
