Constructor Detail

GrailsDataBinder

public GrailsDataBinder(Object target,
                        String objectName)

Create a new GrailsDataBinder instance.

Parameters:

target - target object to bind onto

objectName - objectName of the target object

Method Detail

createBinder

public static GrailsDataBinder createBinder(Object target,
                                            String objectName,
                                            HttpServletRequest request)

Utility method for creating a GrailsDataBinder instance

Parameters:

target - The target object to bind to

objectName - The name of the object

request - A request instance

Returns:

A GrailsDataBinder instance

createBinder

public static GrailsDataBinder createBinder(Object target,
                                            String objectName)

Utility method for creating a GrailsDataBinder instance

Parameters:

target - The target object to bind to

objectName - The name of the object

Returns:

A GrailsDataBinder instance

bind

public void bind(PropertyValues propertyValues)

Overrides:

bind in class DataBinder

bind

public void bind(GrailsParameterMap params)

Binds from a GrailsParameterMap object

Parameters:

params - The GrailsParameterMap object

bind

public void bind(PropertyValues propertyValues,
                 String prefix)

bind

public void bind(ServletRequest request)

Overrides:

bind in class ServletRequestDataBinder

bind

public void bind(ServletRequest request,
                 String prefix)

doBind

protected void doBind(MutablePropertyValues mpvs)

Overrides:

doBind in class WebDataBinder

autoCreateIfPossible

protected void autoCreateIfPossible(MutablePropertyValues mpvs)

Method that auto-creates the a type if it is null and is possible to auto-create

Parameters:

mpvs - A MutablePropertyValues instance

bindAssociations

protected void bindAssociations(MutablePropertyValues mpvs)

Interrogates the specified properties looking for properites that represent associations to other classes (e.g., 'author.id'). If such a property is found, this method attempts to load the specified instance of the association (by ID) and set it on the target object.

Parameters:

mpvs - the MutablePropertyValues object holding the parameters from the request
