Constructor Detail

WicPatternConverter

public WicPatternConverter(int _maxInputLength)

Constructs a WicPatternConverter.

See Also:

maxInputLength()

Method Detail

maxInputLength

public int maxInputLength()

The maximum length of input that will be accepted.

See Also:

convertToObject(String,Locale)

setConvertedInputUnaltered

public final boolean setConvertedInputUnaltered(FormComponent<Pattern> component)

Sets the converted input to the model's current value and returns true; or, if conversion is really needed, leaves it unset and returns false. Call this from your FormComponent.convertInput() in order to guard against multiple redundant conversions. (Why is Wicket requesting them?)

Returns:

true if converted input is set, false otherwise

See Also:

FormComponent.convertInput()

setMaxLength_Type

public <C extends TextField<Pattern>> C setMaxLength_Type(C field)

A convenience method to initialize a text field by adding a 'maxLength' attribute to its view, and by setting a model type of Pattern.

Returns:

the same field

See Also:

maxInputLength()

convertToObject

public final Pattern convertToObject(String input,
                      Locale _ignored)
                              throws IllegalArgumentException

Specified by:

convertToObject in interface IConverter<Pattern>

Throws:

IllegalArgumentException - if input exceeds maxInputLength()

convertToString

public final String convertToString(Pattern value,
                     Locale _ignored)

Specified by:

convertToString in interface IConverter<Pattern>

patternFor

protected Pattern patternFor(String value)
                      throws PatternSyntaxException

Compiles the pattern for a string value. The base implementation of this method (in RegexConverter) simply returns Pattern.compile(value).

Throws:

PatternSyntaxException
