public class Query extends Expression implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2
The Query operator represents a clause-based query. The result of the query is determined by the type of sources included, as well as the clauses used in the query.

      public Query()

  • Method Details

    • getSource

      public List<AliasedQuerySource> getSource()
      Gets the value of the source property.

      This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the JAXB object. This is why there is not a set method for the source property.

      For example, to add a new item, do as follows: 

          getSource().add(newItem);

      Objects of the following type(s) are allowed in the list AliasedQuerySource

    • getLet

      public List<LetClause> getLet()
      Gets the value of the let property.

      This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the JAXB object. This is why there is not a set method for the let property.

      For example, to add a new item, do as follows: 

          getLet().add(newItem);

      Objects of the following type(s) are allowed in the list LetClause

    • getRelationship

      public List<RelationshipClause> getRelationship()
      Gets the value of the relationship property.

      This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the JAXB object. This is why there is not a set method for the relationship property.

      For example, to add a new item, do as follows: 

          getRelationship().add(newItem);

      Objects of the following type(s) are allowed in the list RelationshipClause
