BehavioralRule
public BehavioralRule()
validate
public boolean validate(java.lang.String password,
ValidationInfo validationInfo)
throws InvalidPasswordException
- Validate the given password using the given validation info.
Method overriden by subclass if validate operation supported.
- Specified by:
validate
in interface Rule
- Parameters:
validationInfo
- contains contextual information about the password being validated.password
- Password to validate.- Returns:
- always return true
- Throws:
InvalidPasswordException
- thrown when password is invalid.
join
public boolean join(Rule rule)
throws IncompatibleRulesException
- Try to join the specified rule with this one. The more restrictive
rule takes precedence.
Method overriden by subclass if join operation supported.
- Specified by:
join
in interface Rule
- Parameters:
rule
- The rule to be joined with this one.- Returns:
- always return false
- Throws:
IncompatibleRulesException
- Thrown when given rule cannot be joined because it is not compatible.
constrain
public void constrain(PasswordGenerator generator)
- Some Rule implementing classes will not have a constraint to impose, in which case method
in this class will be called and will do nothing.
- Specified by:
constrain
in interface Rule
- Parameters:
generator
- including a character template to be constrained.
validateSafe
public boolean validateSafe(java.lang.String password,
ValidationInfo validationInfo)
- Validate the given password using the given validation info. This version
will never throw an exception, but will return false if the password is
invalid. It is not possible to get any more information about why the
password failed when using this version.
- Specified by:
validateSafe
in interface Rule
- Parameters:
validationInfo
- contains contextual information about the password being validated.password
- Password to validate.- Returns:
- true if password is valid - false it isn't
getParameter
public java.lang.String getParameter()
- This Rule interface method in is not valid in the context of standard rule classes.
Each standard rule class has its own method for getting constraining parameter value.
- Specified by:
getParameter
in interface Rule
- Following copied from interface:
com.ibm.passwordrules.Rule
- Returns:
- parameter String representing the constraining parameter
setParameter
public void setParameter(java.lang.String parameter)
- This Rule interface method in is not valid in the context of standard rule classes.
Each standard rule class has its own method for setting constraining parameter value.
- Specified by:
setParameter
in interface Rule
- Following copied from interface:
com.ibm.passwordrules.Rule
- Parameters:
parameter
- String representing the constraining parameter
