com.darkcollective.relix.ast.AttributeOperand
Record Components:
name - the attribute name, optionally prefixed with a relation name separated by .; must not be blank
location - the source location of this operand; never null
All Implemented Interfaces:
Operand
public record AttributeOperand(String name, SourceLocation location) extends Record implements Operand
A column reference operand, optionally relation-qualified.

Examples: id, Users.id, user_name

  • Constructor Details

    • AttributeOperand

      public AttributeOperand(String name, SourceLocation location)
      Creates an instance of a AttributeOperand record class.
      Parameters:
      name - the value for the name record component
      location - the value for the location record component

    • AttributeOperand

      public AttributeOperand(String name)
      Convenience constructor for tests; uses SourceLocation.UNKNOWN.

  • Method Details

    • accept

      public <R> R accept(OperandVisitor<R> visitor)
      Specified by:
      accept in interface Operand

    • unqualifiedName

      public String unqualifiedName()
      Returns the column name with any relation qualifier stripped: for Users.id this yields id, for a bare id it returns id unchanged. The qualifier is everything up to and including the last ..

    • 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.

    • name

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

    • location

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