org.litebridgedb.orm.expression.ProtoColumnExpressionSpec
Record Components:
type - The type of expression to create.
column - The column name to select.
alias - The column alias to use, or null if not specified.
All Implemented Interfaces:
ExpressionSpec, ProtoExpressionSpec, Resolvable
public record ProtoColumnExpressionSpec(Class<? extends ExpressionSpec> type, String column, @Nullable String alias, @Nullable Object @Nullable [] args) extends Record implements ProtoExpressionSpec
Proto-expression, used to specify column names/aliases for use in the target expression type.

This record is used to create an expression instance (e.g. SelectColumnSpec) when table information is available.

  • 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.

      public String column()
      Returns the value of the column record component.
      Specified by:
      column in interface Resolvable
      Returns:
      the value of the column record component

    • alias

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