Method Detail

convertToObject

public TYPE convertToObject(java.lang.String string)

Description copied from interface: IStringObjectConverter

Converts an string input to an object.

Specified by:

convertToObject in interface IStringObjectConverter<TYPE>

Parameters:

string - The string to convert.

Returns:

The object that is represented by the string or null if: 1. The string input is not convertible to the OBJECT_TYPE 2. The string represents null

convertToString

public java.lang.String convertToString(TYPE value)

Description copied from interface: IObjectStringConverter

Converts the value to an string representation

Specified by:

convertToString in interface IObjectStringConverter<TYPE>

Parameters:

value - The value to convert

Returns:

the string representation

getDescription

public java.lang.String getDescription(TYPE value)

Description copied from interface: IObjectStringConverter

Gets an description for an value

Specified by:

getDescription in interface IObjectStringConverter<TYPE>

Parameters:

value - the value to get the description for

Returns:

the description or null if there is no description

getStringValidator

public IValidator<java.lang.String> getStringValidator()

Description copied from interface: IStringObjectConverter

Gets a validator that will be used to validate the string input.

Specified by:

getStringValidator in interface IStringObjectConverter<TYPE>

Returns:

A validator or null

getInputVerifier

public IInputVerifier getInputVerifier()

Description copied from interface: IStringObjectConverter

Gets an input verifier that verifies the input. REMARK: Implementors must not assume that the verifier will be used on all platforms, so the validator implementation must consider inputs that won't be verified REMARK: Implementors should prefer to use regular expressions instead of IInputVerifier's if possible because SPI implementations that use 'AJAX' can implement client side verification easier.

Specified by:

getInputVerifier in interface IStringObjectConverter<TYPE>

Returns:

A verifier or null

getAcceptingRegExp

public java.lang.String getAcceptingRegExp()

Description copied from interface: IStringObjectConverter

Gets the regular expression that describes the valid inputs. REMARK: Implementors should prefer to use regular expressions instead of IInputVerifier's if possible because SPI implementations that uses e.g 'AJAX' can implement client side verification easier. REMARK: Implementors must not assume that the regular expression will be used on all platforms

Specified by:

getAcceptingRegExp in interface IStringObjectConverter<TYPE>

Returns:

A regular expression or null

getMask

public ITextMask getMask()

Description copied from interface: IStringObjectConverter

Gets a mask if the input should be masked.

Specified by:

getMask in interface IStringObjectConverter<TYPE>

Returns:

A text mask or null if the input is not masked

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
