StringValidator

public StringValidator()

Creates a new StringValidator with no restrictions.

Method Detail

clearFixed

public void clearFixed()

Clears the fixed value for this ShortValidator.

setFixed

public void setFixed(java.lang.String fixedValue)

Sets the fixed value in which all valid Strings must match.

Parameters:

fixedValue - the fixed value that all Strings must match

setFixedValue

public void setFixedValue(java.lang.String fixedValue)

Deprecated. since 0.9.4_beta

Only used for backward compatibility for object model generated with an old version of Castor.

Parameters:

fixedValue - the fixed value that all Strings must match

setMaxLength

public void setMaxLength(int maxLength)

Sets the maximum string length for String validation. To pass validation, a String must be shorter than or equal to this length. To remove this facet, set a negative value.

Parameters:

maxLength - the maximum length for valid Strings

setMinLength

public void setMinLength(int minLength)

Sets the minimum string length for String validation. To pass validation, a String must be longer than or equal to this length. To remove this facet, set a negative value.

Parameters:

minLength - the minimum length for valid Strings

setLength

public void setLength(int length)

Sets the required string length for String validation. To pass validation, a String must be exactly this many characters long. To remove this facet, set a negative value.

Parameters:

length - the required length for valid Strings

setRequired

public void setRequired(boolean required)

Sets whether or not a String is required (non null).

Parameters:

required - the flag indicating whether this string must be non-null.

setWhiteSpace

public void setWhiteSpace(java.lang.String value)

Sets the whiteSpace facet of the validator.

The value of the whiteSpace facet must be one of the following:

• preserve
• replace
• collapse

any other value will generate a Warning and set the whiteSpace to preserve.

FIXME: This is not really a function of validation, but of XML processing before the string is returned from the XML processor. This should be moved to the FieldHandler, or somewhere else, but not here.

Parameters:

value - the whiteSpace value

normalize

public java.lang.String normalize(java.lang.String value)

Normalizes the given string according to the whiteSpace facet used.

FIXME: THIS METHOD SHOULD NOT BE HERE..SHOULD BE MOVED TO A FieldHandler or to the Unmarshaller...but not here!!! (kvisco 20030125)

Parameters:

value - the String to normalize

Returns:

the normalized string.

validate

public void validate(java.lang.String value,
                     ValidationContext context)
              throws ValidationException

Overrides:

validate in class PatternValidator

Parameters:

object - the Object to validate
