Record Class QuerySpec

java.lang.Object
java.lang.Record
com.onec.query.QuerySpec
Record Components:
from - the root entity class (catalog/document/register)
select - projected columns / ref-navigations / aggregates
where - AND-combined filter predicates
groupBy - grouping paths
orderBy - ordering terms
totals - 1C ИТОГИ hierarchy paths (carried in the AST; tree folding is a follow-up)
limit - optional row cap
offset - optional row offset
public record QuerySpec(Class<?> from, List<Select> select, List<Predicate> where, List<Path> groupBy, List<Order> orderBy, List<Path> totals, Integer limit, Integer offset) extends Record
The declarative AST for a query over any catalog, document, or register — the single source of truth that the fluent builder produces and that the engine compiles to SQL. Being a plain value, the same query is expressible without the fluent API (and, later, as JSON for UI/agents or parsed from a 1C-style text syntax).

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • where

      public List<Predicate> where()
      Returns the value of the where record component.
      Returns:

    • limit

      public Integer limit()
      Returns the value of the limit record component.
      Returns:
      the value of the limit record component
