Record Class ProtoNestableTOExpr<T>

java.lang.Object
java.lang.Record
org.litebridgedb.orm.expression.ProtoNestableTOExpr<T>
Type Parameters:
T - The type override of the expression result.
Record Components:
typeOverride - The type of the expression result.
type - The type of expression to create.
target - The target expression; typically a column name to select via SelectColumnSpec or SelectFieldSpec.
alias - The column alias to use, or null if not specified.
args - Extra expression-specific arguments.
All Implemented Interfaces:
ExpressionSpec, ProtoExpressionSpec, ProtoNestableExpressionSpec, Resolvable, TypeOverride<T>, TypeOverrideExpressionSpec<T>
public record ProtoNestableTOExpr<T>(Class<T> typeOverride, Class<? extends ExpressionSpec> type, ExpressionSpec target, @Nullable String alias, @Nullable Object @Nullable [] args) extends Record implements ProtoNestableExpressionSpec, TypeOverrideExpressionSpec<T>
Type override proto-expression that allows nesting other proto-expressions.

This record is used to create a nested chain of expression instances (e.g. UpperSpec) when table information is available.

  • Method Details

    • returnType

      public Class<T> returnType()
      Description copied from interface: TypeOverride
      Gets the return type override of the query result.
      Specified by:
      returnType in interface TypeOverride<T>
      Returns:
      the type of the result.

    • 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.
