Method Detail

initialize

IntegralDataTypeHolder initialize(long value)
Initialize the internal value from the given primitive long.

Parameters:
value - The primitive integral value.
Returns:
this, for method chaining

initialize

IntegralDataTypeHolder initialize(ResultSet resultSet,
                                  long defaultValue)
                                  throws SQLException
Initialize the internal value from the given result set, using the specified default value if we could not get a value from the result set (aka result was null).

Parameters:
resultSet - The JDBC result set
defaultValue - The default value to use if we did not get a result set value.
Returns:
this, for method chaining
Throws:
SQLException - Any exception from accessing the result set

bind

void bind(PreparedStatement preparedStatement,
          int position)
          throws SQLException
Bind this holders internal value to the given result set.

Parameters:
preparedStatement - The JDBC prepared statement
position - The position at which to bind
Throws:
SQLException - Any exception from accessing the statement

increment

IntegralDataTypeHolder increment()
Equivalent to a ++ operation

Returns:
this, for method chaining

add

IntegralDataTypeHolder add(long addend)

Returns:
this, for method chaining

subtract

IntegralDataTypeHolder subtract(long subtrahend)
Perform a subtraction

Parameters:

Returns:
this, for method chaining

multiplyBy

IntegralDataTypeHolder multiplyBy(IntegralDataTypeHolder factor)
Perform a multiplication.

Parameters:
factor - The factor by which to multiple this integral
Returns:
this, for method chaining

multiplyBy

IntegralDataTypeHolder multiplyBy(long factor)
Perform a multiplication.

Parameters:
factor - The factor by which to multiple this integral
Returns:
this, for method chaining

eq

boolean eq(IntegralDataTypeHolder other)
Perform an equality comparison check

Parameters:
other - The other value to check against our internal state
Returns:
True if the two are equal

eq

boolean eq(long other)
Perform an equality comparison check

Parameters:
other - The other value to check against our internal state
Returns:
True if the two are equal

lt

boolean lt(IntegralDataTypeHolder other)
Perform a "less than" comparison check. We check to see if our value is less than the incoming value...

Parameters:
other - The other value to check against our internal state
Returns:
True if our value is less than the 'other' value.

lt

boolean lt(long other)
Perform a "less than" comparison check. We check to see if our value is less than the incoming value...

Parameters:
other - The other value to check against our internal state
Returns:
True if our value is less than the 'other' value.

gt

boolean gt(IntegralDataTypeHolder other)
Perform a "greater than" comparison check. We check to see if our value is greater than the incoming value...

Parameters:
other - The other value to check against our internal state
Returns:
True if our value is greater than the 'other' value.
