Method Detail

setMessageSource

public void setMessageSource(MessageSource source)

Description copied from interface: Constraint

The message source to evaluate the default messages from

Specified by:

setMessageSource in interface Constraint

Specified by:

setMessageSource in interface MessageSourceAware

getPropertyName

public String getPropertyName()

Specified by:

getPropertyName in interface Constraint

Returns:

The property name of the constraint

setOwningClass

public void setOwningClass(Class constraintOwningClass)

The class the constraint applies to

Specified by:

setOwningClass in interface Constraint

See Also:

Constraint.setOwningClass(java.lang.Class)

setPropertyName

public void setPropertyName(String constraintPropertyName)

Description copied from interface: Constraint

The name of the property the constraint applies to

Specified by:

setPropertyName in interface Constraint

Parameters:

constraintPropertyName - The constraintPropertyName to set.

setParameter

public void setParameter(Object constraintParameter)

Description copied from interface: Constraint

The parameter which the constraint is validated against

Specified by:

setParameter in interface Constraint

Parameters:

constraintParameter - The constraintParameter to set.

checkState

protected void checkState()

validate

public void validate(Object target,
                     Object propertyValue,
                     Errors errors)

Description copied from interface: Constraint

Validate this constraint against a property value. If implementation is vetoing (isVetoing() method returns true), then it could return 'true' to stop further validation.

Specified by:

validate in interface Constraint

propertyValue - The property value to validate

errors - The errors instance to record errors against

skipNullValues

protected boolean skipNullValues()

skipBlankValues

protected boolean skipBlankValues()

rejectValue

                        Errors errors,
                        String defaultMessageCode,
                        Object[] args)

rejectValue

public void rejectValue(Object target,
                        Errors errors,

                        String code,
                        Object[] args)

rejectValue

public void rejectValue(Object target,
                        Errors errors,
                        String defaultMessageCode,
                        String[] codes,
                        Object[] args)

rejectValue

public void rejectValue(Object target,
                        Errors errors,
                        String code,
                        String defaultMessage)

rejectValue

public void rejectValue(Object target,
                        Errors errors,
                        String code,
                        Object[] args,
                        String defaultMessage)

getDefaultMessage

protected String getDefaultMessage(String code)

Returns the default message for the given message code in the current locale. Note that the string returned includes any placeholders that the required message has - these must be expanded by the caller if required.

Parameters:

code - The i18n message code to look up.

Returns:

The message corresponding to the given code in the current locale.

processValidate

protected abstract void processValidate(Object target,
                                        Object propertyValue,
                                        Errors errors)
