Method Detail

validate

public ValidationError validate(Object value,

Parameters:

value - a value of a class supported by the ValidationRule implementation

expressionContext - many validation rules use the xReporter expression interpreter, the expressionContext allows to resolve variables used in these expressions.

supportsType

public boolean supportsType(Class clazz,
                            boolean arrayType)

Description copied from interface: ValidationRule

Returns true if this ValidationRule supports validating objects of the same class as the one specified. If the flag 'arrayType' is true, this method will return true if this validation rule can validate arrays of these objects (i.e. the object passed to the validate method will then be an array).

isValidDomain

protected boolean isValidDomain(String domain)

Returns true if the domain component of an email address is valid.

Parameters:

domain - being validatied.

isValidUser

protected boolean isValidUser(String user)

Returns true if the user component of an email address is valid.

Parameters:

user - being validated

isValidIpAddress

protected boolean isValidIpAddress(org.apache.oro.text.perl.Perl5Util ipAddressMatcher)

Validates an IP address. Returns true if valid.

Parameters:

ipAddressMatcher - Pattren matcher

isValidSymbolicDomain

protected boolean isValidSymbolicDomain(String domain)

Validates a symbolic domain name. Returns true if it's valid.

Parameters:
