Record Class EntityMeta

java.lang.Object
java.lang.Record
com.onec.query.EntityMeta
public record EntityMeta(EntityMeta.Kind kind, Class<?> type, String table, String pk, Map<String,String> systemColumns, List<AttributeDescriptor> attributes) extends Record
A query-layer view over a single queryable entity (catalog / document / register), unifying the per-kind descriptors behind one shape: table name, primary-key column, the built-in system columns, and the user attributes.

The systemColumns map keys are bean-property names (as resolved from getter references) and values are physical column names — mirroring the framework's naming convention (description -> _description, number -> _number, …).

  • Method Details

    • column

      public String column(String field)
      Physical column for a bean-property name, or null if unknown.

    • attribute

      public AttributeDescriptor attribute(String field)
      Attribute descriptor for a property name, or null for system / unknown fields.

    • 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:
