---|---|
java.lang.Class<?> |
getPropertyType(java.lang.String propertyName)
Determine the property type for the specified property,
either checking the property descriptor or checking the value
in case of an indexed or mapped element.
|
TypeDescriptor |
getPropertyTypeDescriptor(java.lang.String propertyName)
Return a type descriptor for the specified property:
preferably from the read method, falling back to the write method.
|
java.lang.Object |
getPropertyValue(java.lang.String propertyName)
Get the current value of the specified property.
|
boolean |
isReadableProperty(java.lang.String propertyName)
Determine whether the specified property is readable.
|
boolean |
isWritableProperty(java.lang.String propertyName)
Determine whether the specified property is writable.
|
void |
setPropertyValue(PropertyValue pv)
Set the specified value as current property value.
|
void |
setPropertyValue(java.lang.String propertyName,
java.lang.Object value)
Set the specified value as current property value.
|
void |
setPropertyValues(java.util.Map<?,?> map)
Perform a batch update from a Map.
|
void |
setPropertyValues(PropertyValues pvs)
The preferred way to perform a batch update.
|
void |
setPropertyValues(PropertyValues pvs,
boolean ignoreUnknown)
Perform a batch update with more control over behavior.
|
void |
setPropertyValues(PropertyValues pvs,
boolean ignoreUnknown,

void setPropertyValues(java.util.Map<?,?> map) throws BeansException
Bulk updates from PropertyValues are more powerful: This method is
provided for convenience. Behavior will be identical to that of
the setPropertyValues(PropertyValues)
method.

- Map to take properties from. Contains property value objects,
keyed by property nameInvalidPropertyException
- if there is no such property or
if the property isn't writablePropertyBatchUpdateException
- if one or more PropertyAccessExceptions
occured for specific properties during the batch update. This exception bundles
all individual PropertyAccessExceptions. All other properties will have been
successfully updated.BeansException
void setPropertyValues(PropertyValues pvs) throws BeansException
Note that performing a batch update differs from performing a single update,
in that an implementation of this class will continue to update properties
if a recoverable error (such as a type mismatch, but not an
invalid field name or the like) is encountered, throwing a
PropertyBatchUpdateException
containing all the individual errors.
This exception can be examined later to see all binding errors.
Properties that were successfully updated remain changed.
Does not allow unknown fields or invalid fields.

if the property isn't writablePropertyBatchUpdateException
- if one or more PropertyAccessExceptions
occured for specific properties during the batch update. This exception bundles
