Constructor Detail

ValidationServiceValidator

public ValidationServiceValidator(DefaultValidationService service,
                                  ValidationService theParentService)

Default constructor.

Parameters:

service - The validation service this validator represents

theParentService - The parent validation service

Method Detail

validate

public boolean validate(InternalValidatorContext context,
                        ContextBean contextBean,
                        ValidationTrace trace,
                        java.lang.Object obj)

Description copied from interface: ValidatorWrapper

Called to have the wrapper validate the passed object. It is expected that the wrapper will update the root object as appropriate. The context already has access to the root that is being passed in.

Specified by:

validate in interface ValidatorWrapper

Parameters:

context - The validation context to pass on to the contained validator.

contextBean - The OGNL root, to be updated as appropriate.

trace - The validation trace to track what calls what.

obj - The object to be validated.

Returns:

Returns true if validation should continue; false if it should be halted.

setIfExpression

public void setIfExpression(java.lang.String exp)

getIfExpression

public java.lang.String getIfExpression()

setIterateExpression

public void setIterateExpression(java.lang.String exp)

getIterateExpression

public java.lang.String getIterateExpression()

setMapExpression

public void setMapExpression(java.lang.String exp)

getMapExpression

public java.lang.String getMapExpression()

setFailFast

public void setFailFast(boolean flag)

isFailFast

public boolean isFailFast()

setName

public void setName(java.lang.String theName)

getName

public java.lang.String getName()

Description copied from interface: ValidatorWrapper

Called to retrieve the "name" of the validator. The name represents some form of identification, though it does not have to be unique in any way. The name is merely associated with the configured validator, and is referenced when reporting failures.

Specified by:

getName in interface ValidatorWrapper

Returns:

Returns the name of this validator.

getDoc

public DocumentationIterator getDoc()

Called to retrieve the documentation for the validator.

Specified by:

getDoc in interface ValidatorWrapper

Returns:

Returns the documentation for the validator.

shouldIterate

protected abstract boolean shouldIterate(InternalValidatorContext context,
                                         ContextBean contextBean,
                                         java.lang.Object obj)

Determines whether we're iterating over the mapped object.

Parameters:

context - The ValidatorContext

contextBean - The ContextBean

obj - The object being validated.

Returns:

Returns true if we should iterate.

shouldExecute

protected abstract boolean shouldExecute(InternalValidatorContext context,
                                         ContextBean contextBean,
                                         java.lang.Object obj)

Determines whether the inclusion/call to the validation set should occur.

Parameters:

context - The ValidatorContext

contextBean - The ContextBean

obj - The object being validated.

Returns:

Returns true if the validation set should be called/executed.

mapObject

protected abstract java.lang.Object mapObject(InternalValidatorContext context,
                                              ContextBean contextBean,
                                              java.lang.Object obj)

Handle the mapping of the object being validated to the property that will be validated (may be the object, itself).

Parameters:

context - The ValidatorContext

contextBean - The ContextBean

obj - The object being validated.

Returns:

Returns the object that will be forwarded to the called validation set.

createNewContext

protected InternalValidatorContext createNewContext(ContextBean newContextBean,
                                                    java.util.Locale newLocale,
                                                    InternalValidatorContext oldContext)

Constructs a new context for the validation set being called.

Parameters:

newContextBean - The new ContextBean created for the validation set.

newLocale - The new Locale for the validation set.

oldContext - The old ValidatorContext from the current validation set.
