Record Class ElementOfPredicate

java.lang.Object
java.lang.Record
com.darkcollective.relix.ast.ElementOfPredicate
Record Components:
element - the element to test; must not be null
setExpression - the set expression to test membership in; must not be null
isNegated - true for ∉ (not element of), false for ∈ (element of)
location - the source location of this predicate; never null
All Implemented Interfaces:
Predicate
public record ElementOfPredicate(Operand element, Operand setExpression, boolean isNegated, SourceLocation location) extends Record implements Predicate
Represents element-of predicates: element ∈ set_expression or element ∉ set_expression Used for set membership testing (equivalent to SQL IN/NOT IN).

  • Constructor Details

    • ElementOfPredicate

      public ElementOfPredicate(Operand element, Operand setExpression, boolean isNegated, SourceLocation location)
      Creates an instance of a ElementOfPredicate record class.
      Parameters:
      element - the value for the element record component
      setExpression - the value for the setExpression record component
      isNegated - the value for the isNegated record component
      location - the value for the location record component

    • ElementOfPredicate

      public ElementOfPredicate(Operand element, Operand setExpression, boolean isNegated)
      Convenience constructor for tests; uses SourceLocation.UNKNOWN.

  • Method Details

    • accept

      public <R> R accept(PredicateVisitor<R> visitor)
      Specified by:
      accept in interface Predicate

    • 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.

    • element

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

    • setExpression

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

    • isNegated

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

    • location

      public SourceLocation location()
      Returns the value of the location record component.
      Specified by:
      location in interface Predicate
      Returns:
      the value of the location record component
