Constructor Detail

GrailsDataBinder

@SuppressWarnings("unchecked")
public GrailsDataBinder(java.lang.Object target, java.lang.String objectName)
Create a new GrailsDataBinder instance.
Parameters:
target - target object to bind onto
objectName - objectName of the target object

 
Method Detail

autoCreateIfPossible

protected void autoCreateIfPossible(MutablePropertyValues mpvs)
Auto-creates the a type if it is null and is possible to auto-create.
Parameters:
mpvs - A MutablePropertyValues instance

bind

@Override
public void bind(PropertyValues propertyValues)

bind

public void bind(GrailsParameterMap params)
Binds from a GrailsParameterMap object
Parameters:
params - The GrailsParameterMap object

bind

public void bind(GrailsParameterMap params, java.lang.String prefix)

bind

public void bind(PropertyValues propertyValues, java.lang.String prefix)

bind

@Override
public void bind(ServletRequest request)

bind

public void bind(ServletRequest request, java.lang.String prefix)

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

checkFieldMarkers

@Override
protected void checkFieldMarkers(MutablePropertyValues mpvs)
This overrides the method from WebDataBinder to allow for nested checkbox handling, so property paths such as a._b will result in the boolean b on object a getting set to false.

createBinder

public static GrailsDataBinder createBinder(java.lang.Object target, java.lang.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(java.lang.Object target, java.lang.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

doBind

@Override
protected void doBind(MutablePropertyValues mpvs)

registerCustomEditors

public static void registerCustomEditors(PropertyEditorRegistry registry, java.util.Locale locale)
Registers all known
Parameters:
registry
locale
