org.zkoss.zul .SimpleConstraint

All known Subclasses:   org.zkoss.zul .SimpleDateConstraint,
SimpleConstraint
public class SimpleConstraint implements Constraint,ClientConstraint,java.io.Serializable(Code)
A simple constraint that you could build based the predefined constants.
Depending on the component (such as Intbox and Datebox , you could combine the flags, such as SimpleConstraint.NO_POSITIVE + SimpleConstraint.NO_ZERO to accept only negative number.

     Parses a constraint into an integer value.
public void validate(Component comp, Object value)


Field Detail
NO_EMPTY
final public static int NO_EMPTY(Code)
Empty is not allowed. If not specified, empty usually means null.

NO_FUTURE
final public static int NO_FUTURE(Code)
Date in the future is not allowed. (Only date part is compared)

NO_NEGATIVE
final public static int NO_NEGATIVE(Code)
Negative numbers are not allowed.

NO_PAST
final public static int NO_PAST(Code)
Date in the past is not allowed. (Only date part is compared)

NO_POSITIVE
final public static int NO_POSITIVE(Code)
Postive numbers are not allowed.

NO_TODAY
final public static int NO_TODAY(Code)
Today is not allowed. (Only date part is compared)

NO_ZERO
final public static int NO_ZERO(Code)
Zero numbers are not allowed.

STRICT
final public static int STRICT(Code)
The value must match inside the data from ListModel only.

_flags
protected int _flags(Code)
The constraints. A combination of SimpleConstraint.NO_POSITIVE and others.

Constructor Detail
SimpleConstraint
public SimpleConstraint(int flags)(Code)
Constructs a constraint with flags.
Parameters:
  flags - a combination of SimpleConstraint.NO_POSITIVE, SimpleConstraint.NO_NEGATIVE,SimpleConstraint.NO_ZERO, and so on.

Parameters:
  flags - a combination of SimpleConstraint.NO_POSITIVE, SimpleConstraint.NO_NEGATIVE,SimpleConstraint.NO_ZERO, and so on.
Parameters:
  errmsg - the error message to display. Ignored if null or empty.

SimpleConstraint
public SimpleConstraint(String regex, String errmsg)(Code)
Constructs a regular-expression constraint.
Parameters:
  regex - ignored if null or empty
Parameters:
  errmsg - the error message to display. Ignored if null or empty.

SimpleConstraint
public SimpleConstraint(int flags, String regex, String errmsg)(Code)
Constructs a constraint combining regular expression.
Parameters:
  flags - a combination of SimpleConstraint.NO_POSITIVE, SimpleConstraint.NO_NEGATIVE,SimpleConstraint.NO_ZERO, and so on.
Parameters:
  regex - ignored if null or empty
Parameters:
  errmsg - the error message to display. Ignored if null or empty.

SimpleConstraint
public SimpleConstraint(String constraint)(Code)
Constructs a constraint with a list of constraints separated by comma.
Parameters:
  constraint - a list of constraints separated by comma.Example: no positive, no zero
since:
   3.0.2

Method Detail
getClientValidation
public String getClientValidation()(Code)

getErrorMessage
public String getErrorMessage(Component comp)(Code)

getFlags
public int getFlags()(Code)
Returns the constraint flags, i.e., a combination of SimpleConstraint.NO_POSITIVE , SimpleConstraint.NO_NEGATIVE , SimpleConstraint.STRICT and others.
since:
   3.0.2

getInstance
final public static SimpleConstraint getInstance(String constraint)(Code)
Parses a list of constraints from a string to an integer representing a combination of SimpleConstraint.NO_POSITIVE and other flags.
Parameters:
  constraint - a list of constraints separated by comma.Example: no positive, no zero

isClientComplete
public boolean isClientComplete()(Code)

parseConstraint
protected int parseConstraint(String constraint) throws UiException(Code)
Parses a constraint into an integer value. For example, "no positive" is parsed to SimpleConstraint.NO_POSITIVE .
Deriving classes might override this to provide more constraints.
