Method Detail

registerTypeConverter

public static void registerTypeConverter(TypeConverter<?,java.lang.Integer> converter)

This method registers with this static utility an instance of a Integer TypeConverter to convert an instance of the convertible class into a Integer value

Parameters:

converter - The Integer TypeConverter instance

toInteger

public static java.lang.Integer toInteger(java.lang.Object v)

This method converts the given object into a Integer value Static utility methods convert Strings, Integers, Longs, Floats, Doubles, Dates and Booleans into Integer values If the given object is not one of the above types then a type converter must have been registered with this static utility in order for the given object to be converted into a Integer value If no type converter has been registered for the class of the given object then a null is returned

Parameters:

v - The object to convert into a Integer value

Returns:

The Integer representation of the given object or null if the given object is null or the class of the given object cannot be converted into a Integer value

toLong

public static java.lang.Long toLong(java.lang.Integer v)

                                       java.lang.Integer max)

This method returns a random integer within the specified range inclusive

Parameters:

min - The minimum value for the random integer

max - The maximum value for the random integer

Returns:

A random integer within the given range.

nvl

public static java.lang.Integer nvl(java.lang.Integer checkValue,
                                    java.lang.Integer valueIfNull)

This method converts null values
