Class IntegerSyntax is an abstract base class providing the common implementation of all attributes with integer values.

Under the hood, an integer attribute is just an integer. You can get an integer attribute's integer value by calling getValue(). An integer attribute's integer value is established when it is constructed (see IntegerSyntax(int)). Once constructed, an integer attribute's value is immutable.

Construct a new integer attribute with the given integer value.
Params:

Construct a new integer attribute with the given integer value, which must lie within the given range.
Params:
  • value – Integer value
  • lowerBound – Lower bound
  • upperBound – Upper bound
Throws:
/** * Construct a new integer attribute with the given integer value, which * must lie within the given range. * * @param value Integer value * @param lowerBound Lower bound * @param upperBound Upper bound * @throws IllegalArgumentException if {@code value} is less than * {@code lowerBound} or greater than {@code upperBound} */

Returns whether this integer attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:
  1. object is not null.
  2. object is an instance of class IntegerSyntax.
  3. This integer attribute's value and object's value are equal.
Params:
  • object – Object to compare to
Returns:true if object is equivalent to this integer attribute, false otherwise

Returns a hash code value for this integer attribute. The hash code is just this integer attribute's integer value.

Returns a string value corresponding to this integer attribute. The string value is just this integer attribute's integer value converted to a string.
