java.lang.Object
java.lang.Record
com.libdbm.cel.ast.Literal
Record Components:
value - the literal runtime value (boxed as needed); may be null for NULL_VALUE
type - the literal kind to disambiguate numeric/string/bytes/null forms
All Implemented Interfaces:
Expression
public record Literal(Object value, LiteralType type) extends Record implements Expression
Represents a literal value in CEL expressions. Examples: null, true, 42, 3.14, "hello", b"bytes"

  • Constructor Details

    • Literal

      public Literal(Object value, LiteralType type)
      Creates an instance of a Literal record class.
      Parameters:
      value - the value for the value record component
      type - the value for the type record component

  • Method Details

    • accept

      public <T> T accept(Expression.Visitor<T> visitor)
      Accepts a visitor to perform operations on this expression node.

      Invokes the appropriate visit method on the provided visitor, dispatching the visit operation to the visitor implementation that corresponds to the type of this expression node.

      Specified by:
      accept in interface Expression
      Type Parameters:
      T - the return type of the visitor's visit operations
      Parameters:
      visitor - the visitor that will operate on this expression node
      Returns:
      the result of the visitor's visit operation

    • 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.

    • value

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

    • type

      public LiteralType type()
      Returns the value of the type record component.
      Returns:
      the value of the type record component
