Constructor Detail

StringLengthValidator

public StringLengthValidator(String errorMessage)

Deprecated.

Creates a new StringLengthValidator with a given error message.

Parameters:

errorMessage - the message to display in case the value does not validate.

StringLengthValidator

public StringLengthValidator(String errorMessage,
                             Integer minLength,
                             Integer maxLength,
                             boolean allowNull)

Deprecated.

Creates a new StringLengthValidator with a given error message and minimum and maximum length limits.

Parameters:

errorMessage - the message to display in case the value does not validate.

minLength - the minimum permissible length of the string or null for no limit. A negative value for no limit is also supported for backwards compatibility.

maxLength - the maximum permissible length of the string or null for no limit. A negative value for no limit is also supported for backwards compatibility.

allowNull - Are null strings permissible? This can be handled better by setting a field as required or not.
