Method Detail

convert

public Double convert(String input,
             Class<? extends Double> targetType,
             Collection<ValidationError> errors)

Converts the input to an object of type Double.

Specified by:

convert in interface TypeConverter<Double>

Parameters:

input - the String being converted

targetType - the Class representing the type of the property to which the return value of the conversion will be assigned. In many cases this can be ignored as converters will return a single type more often than not.

errors - an empty collection of validation errors that should be populated by the converter for any errors that occur during validation that are user input related.

Returns:

T an instance of the converted type, or null if the input cannot be converted
