Constructor Detail

DecimalFormatPropertyType

public DecimalFormatPropertyType()

Returns DecimalFormatPropertyType where the default value is null.

DecimalFormatPropertyType

public DecimalFormatPropertyType(String defaultValue)
                          throws IllegalArgumentException

Returns DecimalFormatPropertyType with default value.

Parameters:

defaultValue - a new instance of DecimalFormat with the decimalFormatPattern is constructed as defaultValue.

Throws:

IllegalArgumentException - if "decimalFormatPattern" is invalid.

DecimalFormatPropertyType

public DecimalFormatPropertyType(DecimalFormat defaultValue)

Returns DecimalFormatPropertyType with default value.

Parameters:

defaultValue - default value returned if property value is undefined.

Method Detail

getRestrictions

public List<String> getRestrictions()

Description copied from class: PropertyType

Gets a detailed description of the PropertyType with any constraints that might influence the validation.
This includes a description for the default value, if the default do not it self parse the validation of the type, the exception is appended to the description.

Specified by:

getRestrictions in class PropertyType<DecimalFormat>

Returns:

the restrictions of the PropertyType as a list of strings.

validateValue

public DecimalFormat validateValue(String propertyName,
                                   String value)
                            throws PropertyException

Description copied from class: PropertyType

Converts the string representation of to a typed value.
Including validation of any restrictions the PropertyType might have.
See the individual property type class description for details on how it convert to a typed value.

IMPORTANT: This only validates the value not the constraints of the PropertyType, which is at this point assumed to be valid.

Specified by:

validateValue in class PropertyType<DecimalFormat>

Parameters:

propertyName - the name of the property used for logging purposes. To uniquely identify the Property with validation issues.

value - the string representation of the property

Returns:

the typed converted value.

Throws:

PropertyException - if the conversion failed.

toString

public String toString(String propertyName,
                       DecimalFormat t)
                throws PropertyException

Description copied from class: PropertyType

Converts a typed to the string representation. This must be associative, so the string generate here will successful validate. This is enforced, so the converted string is sub sequencetially validate with the validate method. In some of the property sub types, this method is overridden to ensure above rule.

Overrides:

toString in class PropertyType<DecimalFormat>

Parameters:

propertyName - the name of the property used for logging purposes.

t - the type T.

Returns:

The string representation of the type.

Throws:

PropertyException - if conversion failed in validation.
