Record Class ProtoNestableBasicExprSpec

java.lang.Object
java.lang.Record
org.litebridgedb.orm.expression.ProtoNestableBasicExprSpec
Record Components:
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.
All Implemented Interfaces:
ExpressionSpec, ProtoExpressionSpec, ProtoNestableExpressionSpec, Resolvable
public record ProtoNestableBasicExprSpec(Class<? extends ExpressionSpec> type, ProtoExpressionSpec target, @Nullable String alias) extends Record implements ProtoNestableExpressionSpec
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.

  • Constructor Details

    • ProtoNestableBasicExprSpec

      public ProtoNestableBasicExprSpec(Class<? extends ExpressionSpec> type, ProtoExpressionSpec target, @Nullable String alias)
      Creates an instance of a ProtoNestableBasicExprSpec record class.
      Parameters:
      type - the value for the type record component
      target - the value for the target record component
      alias - the value for the alias record component

    • ProtoNestableBasicExprSpec

      public ProtoNestableBasicExprSpec(Class<? extends ExpressionSpec> type, String column, @Nullable String alias)
      Constructs a new ProtoNestableBasicExprSpec instance via column name.
      Parameters:
      type - The type of expression to create.
      column - The target column name to select.
      alias - The column alias to use, or null if not specified.

  • Method Details

    • args

      public @Nullable Object @Nullable [] args()
      Description copied from interface: ProtoExpressionSpec
      Gets any extra expression-specific arguments.
      Specified by:
      args in interface ProtoExpressionSpec
      Returns:
      the extra arguments, or null if none

    • 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.

    • type

      public Class<? extends ExpressionSpec> type()
      Returns the value of the type record component.
      Specified by:
      type in interface Resolvable
      Returns:
      the value of the type record component

    • target

      public ProtoExpressionSpec target()
      Returns the value of the target record component.
      Specified by:
      target in interface ProtoNestableExpressionSpec
      Returns:
      the value of the target record component

    • alias

      public @Nullable String alias()
      Returns the value of the alias record component.
      Specified by:
      alias in interface ProtoExpressionSpec
      Returns:
      the value of the alias record component
