Constructor Detail

QueryFactories

public QueryFactories(DFDataTree dataTree,
                      DBDatabaseInfo dbInfo,
                      String identifierQuoteString)

Creates a new instance of QueryWidgetFactory

QueryFactories

public QueryFactories(DFEntity entity)

Queries for only this Entity. No relational queries.

QueryFactories

public QueryFactories(DFDataTree dataTree)

Queries for this data tree, including relational queries

Method Detail

getShortQueryWidgetDescription

public static String getShortQueryWidgetDescription(DFTermExpression query)

createCompositeQueryTerm

public DFTermExpression createCompositeQueryTerm(DFOperator op,
                                                 List<DFTermExpression> children)

Create a default AND or OR query term for this field. The options will be created as a new HashMap() with a zero length path identified by the key DATA_TREE_PATH

createCompositeQueryTerm

public DFTermExpression createCompositeQueryTerm(DFOperator op,
                                                 List<DFTermExpression> children,
                                                 Map<String,Object> options)

Create composite term. The options must exist and contain a path identified by the key DATA_TREE_PATH

createFieldOperatorValueQueryTerm

public DFTermExpression createFieldOperatorValueQueryTerm(DFField field,
                                                          boolean ignore)

Create a default field operator value query term for this field TODO - we need to be able to specify the operator, but we need a mechanism to work out which should be the default.

Parameters:

field - The field

ignore - If true then the operator is set to null. If false the first operator is set.

Returns:

The query term

createFieldOperatorValueQueryTerm

public DFTermExpression createFieldOperatorValueQueryTerm(DFField field,
                                                          DFOperator op,
                                                          Object... values)
