Constructor Detail

AbstractPropertyBindingResult

protected AbstractPropertyBindingResult(String objectName)

Create a new AbstractPropertyBindingResult instance.

Parameters:

objectName - the name of the target object

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.

ConfigurablePropertyAccessor.setExtractOldValueForEditor(boolean)
