Class BooleanLiteral

All Implemented Interfaces:
SQLLiteral

public class BooleanLiteral extends BooleanExpression implements SQLLiteral
Representation of a Boolean literal in a Query.
  • Field Details

    • value

      private final Boolean value
  • Constructor Details

    • BooleanLiteral

      public BooleanLiteral(SQLStatement stmt, JavaTypeMapping mapping, Object value, String parameterName)
      Creates a boolean literal with the specified value, using the provided mapping. The boolean literal DOESN'T have closure using this constructor. This constructor will use the provided mapping in determining whether to put "TRUE"/"1=0", or "1"/"0" or "Y"/"N" in the SQL.
      Parameters:
      stmt - The SQL statement
      mapping - the mapping
      value - the value
      parameterName - Parameter name (represented as JDBC "?")
    • BooleanLiteral

      public BooleanLiteral(SQLStatement stmt, JavaTypeMapping mapping, Boolean value)
      Creates a boolean literal with the specified value, using the provided mapping. The boolean expression has closure using this constructor. This constructor doesn't take into account the type of the mapping and how a boolean may be stored, just creating a literal (TRUE) and the SQL will simply be "TRUE"/"1=0".
      Parameters:
      stmt - The SQL statement
      mapping - the mapping
      value - the boolean value
  • Method Details

    • setJavaTypeMapping

      public void setJavaTypeMapping(JavaTypeMapping mapping)
      Overrides:
      setJavaTypeMapping in class SQLExpression
    • getValue

      public Object getValue()
      Description copied from interface: SQLLiteral
      Accessor to the literal value
      Specified by:
      getValue in interface SQLLiteral
      Returns:
      the value of the literal
    • and

      public BooleanExpression and(SQLExpression expr)
      Description copied from class: SQLExpression
      Conditional AND. Evaluates its right-hand operand only if the value of its left-hand operand is true.
      Overrides:
      and in class BooleanExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      the result value is true if both operand values are true; otherwise, the result is false.
    • eor

      public BooleanExpression eor(SQLExpression expr)
      Description copied from class: SQLExpression
      Exclusive OR
      Overrides:
      eor in class BooleanExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      the result value is the bitwise exclusive OR of the operand values.
    • ior

      public BooleanExpression ior(SQLExpression expr)
      Description copied from class: SQLExpression
      Conditional OR. Evaluates its right-hand operand only if the value of its left-hand operand is false.
      Overrides:
      ior in class BooleanExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      the result value is false if both operand values are false; otherwise, the result is true.
    • not

      public BooleanExpression not()
      Description copied from class: SQLExpression
      Logical complement
      Overrides:
      not in class BooleanExpression
      Returns:
      the result value is false if operand is true; otherwise, the result is true.
    • eq

      public BooleanExpression eq(SQLExpression expr)
      Description copied from class: SQLExpression
      Equality operator (equals to)
      Overrides:
      eq in class BooleanExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      The type of an equality expression is a boolean
    • ne

      public BooleanExpression ne(SQLExpression expr)
      Description copied from class: SQLExpression
      Not equality operator (not equals to)
      Overrides:
      ne in class BooleanExpression
      Parameters:
      expr - the right-hand operand
      Returns:
      The type of an equality expression is a boolean
    • setNotParameter

      public void setNotParameter()
      Description copied from interface: SQLLiteral
      Method to set this literal as not being a parameter. If the literal if not currently a parameter then does nothing. Updates any underlying SQL to have the value.
      Specified by:
      setNotParameter in interface SQLLiteral
    • setStatement

      protected void setStatement()
