Record Class WindowClause.WindowCondition

java.lang.Object
java.lang.Record
org.rumbledb.expressions.flowr.WindowClause.WindowCondition
Record Components:
variables - Variables bound to the condition (for example, $start in start at $s when fn:true()
expression - boolean expression that triggers the start / end of window
only - If a start item is identified, but no following item in the binding sequence satisfies the WindowEndCondition, then the only keyword determines whether a window is generated: if only end is specified, then no window is generated; otherwise, the end item is set to the last item in the binding sequence and a window is generated.
Enclosing class:
WindowClause
public static record WindowClause.WindowCondition(WindowClause.WindowVars variables, Expression expression, boolean only) extends Record
Record to keep the start or end condition of a window clause

  • Constructor Details

    • WindowCondition

      public WindowCondition(WindowClause.WindowVars variables, Expression expression, boolean only)
      Creates an instance of a WindowCondition record class.
      Parameters:
      variables - the value for the variables record component
      expression - the value for the expression record component
      only - the value for the only 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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      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.

    • variables

      public WindowClause.WindowVars variables()
      Returns the value of the variables record component.
      Returns:
      the value of the variables record component

    • expression

      public Expression expression()
      Returns the value of the expression record component.
      Returns:
      the value of the expression record component

    • only

      public boolean only()
      Returns the value of the only record component.
      Returns:
      the value of the only record component
