Record Class SolveStart

java.lang.Object
java.lang.Record
com.darkcollective.relix.ast.SolveStart
Record Components:
column - the unknown column the start is for; never blank
value - the starting value, an expression over the row's known columns; never null
public record SolveStart(String column, Operand value) extends Record
Where a SolveNode's iterative search starts for one unknown: START column = value.

value is evaluated over the row being solved, so the start may differ from row to row. It matters only when the unknown is found by search; an equation that is inverted or eliminated has one answer and ignores it.

  • Constructor Details

    • SolveStart

      public SolveStart(String column, Operand value)
      Creates an instance of a SolveStart record class.
      Parameters:
      column - the value for the column record component
      value - the value for the value record component

  • 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.

    • column

      public String column()
      Returns the value of the column record component.
      Returns:
      the value of the column record component

    • value

      public Operand value()
      Returns the value of the value record component.
      Returns:
      the value of the value record component
