Constructor Detail

AbstractPropertyBindingResult

protected AbstractPropertyBindingResult(String objectName)

Create a new AbstractPropertyBindingResult instance.

Parameters:: objectName - the name of the target object
See Also:: DefaultMessageCodesResolver

Method Detail

getPropertyEditorRegistry

public PropertyEditorRegistry getPropertyEditorRegistry()

Returns the underlying PropertyAccessor.

Specified by:: getPropertyEditorRegistry in interface BindingResult
Overrides:: getPropertyEditorRegistry in class AbstractBindingResult

See Also:: getPropertyAccessor()

canonicalFieldName

protected String canonicalFieldName(String field)

Returns the canonical property name.

Overrides:: canonicalFieldName in class AbstractBindingResult

Parameters:: field - the original field name
Returns:: the canonical field name
See Also:: PropertyAccessorUtils.canonicalPropertyName(java.lang.String)

getFieldType

public Class getFieldType(String field)

Determines the field type from the property type.

Specified by:: getFieldType in interface Errors
Overrides:: getFieldType in class AbstractBindingResult

Parameters:: field - the field name
Returns:: the type of the field, or null if not determinable
See Also:: getPropertyAccessor()

getActualFieldValue

protected Object getActualFieldValue(String field)

Fetches the field value from the PropertyAccessor.

Specified by:: getActualFieldValue in class AbstractBindingResult

Parameters:: field - the field to check
Returns:: the current value of the field
See Also:: getPropertyAccessor()

formatFieldValue

protected Object formatFieldValue(String field,
                                  Object value)

Formats the field value based on registered PropertyEditors.

Overrides:: formatFieldValue in class AbstractBindingResult

Parameters:: field - the field to check; value - the value of the field (either a rejected value other than from a binding error, or an actual field value)
Returns:: the formatted value
See Also:: getCustomEditor(java.lang.String)

getCustomEditor

public PropertyEditor getCustomEditor(String field)

Retrieve the custom PropertyEditor for the given field, if any.

Parameters:: field - the field name
Returns:: the custom PropertyEditor, or null

getPropertyAccessor

public abstract ConfigurablePropertyAccessor getPropertyAccessor()

Provide the PropertyAccessor to work with, according to the concrete strategy of access.

Note that a PropertyAccessor used by a BindingResult should always have its "extractOldValueForEditor" flag set to "true" by default, since this is typically possible without side effects for model objects that serve as data binding target.

See Also:: ConfigurablePropertyAccessor.setExtractOldValueForEditor(boolean)
