方法详细资料

• setExtractOldValueForEditor

  public void setExtractOldValueForEditor​(boolean extractOldValueForEditor)

  从接口复制的说明: ConfigurablePropertyAccessor
  Set whether to extract the old property value when applying a property editor to a new value for a property.

  指定者:

  setExtractOldValueForEditor 在接口中 ConfigurablePropertyAccessor

• isExtractOldValueForEditor

  public boolean isExtractOldValueForEditor()

  从接口复制的说明: ConfigurablePropertyAccessor
  Return whether to extract the old property value when applying a property editor to a new value for a property.

  指定者:

  isExtractOldValueForEditor 在接口中 ConfigurablePropertyAccessor

• setAutoGrowNestedPaths

  public void setAutoGrowNestedPaths​(boolean autoGrowNestedPaths)

  从接口复制的说明: ConfigurablePropertyAccessor
  Set whether this instance should attempt to "auto-grow" a nested path that contains a null value.

  If true, a null path location will be populated with a default object value and traversed instead of resulting in a NullValueInNestedPathException.

  Default is false on a plain PropertyAccessor instance.

  指定者:

  setAutoGrowNestedPaths 在接口中 ConfigurablePropertyAccessor

• isAutoGrowNestedPaths

  public boolean isAutoGrowNestedPaths()

  从接口复制的说明: ConfigurablePropertyAccessor
  Return whether "auto-growing" of nested paths has been activated.

  指定者:

  isAutoGrowNestedPaths 在接口中 ConfigurablePropertyAccessor

• setPropertyValue

  public void setPropertyValue​(PropertyValue pv)
                        throws BeansException

  从接口复制的说明: PropertyAccessor
  Set the specified value as current property value.

  指定者:

  setPropertyValue 在接口中 PropertyAccessor

  参数:

  pv - an object containing the new property value

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't writable

  PropertyAccessException - if the property was valid but the accessor method failed or a type mismatch occurred

  BeansException

• setPropertyValues

  public void setPropertyValues​(Map<?,​?> map)
                         throws BeansException

  从接口复制的说明: PropertyAccessor
  Perform a batch update from a Map.

  Bulk updates from PropertyValues are more powerful: This method is provided for convenience. Behavior will be identical to that of the PropertyAccessor.setPropertyValues(PropertyValues) method.

  指定者:

  setPropertyValues 在接口中 PropertyAccessor

  参数:

  map - Map to take properties from. Contains property value objects, keyed by property name

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't writable

  PropertyBatchUpdateException - if one or more PropertyAccessExceptions occurred for specific properties during the batch update. This exception bundles all individual PropertyAccessExceptions. All other properties will have been successfully updated.

  BeansException

• setPropertyValues

  public void setPropertyValues​(PropertyValues pvs)
                         throws BeansException

  从接口复制的说明: PropertyAccessor
  The preferred way to perform a batch update.

  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.

  指定者:

  setPropertyValues 在接口中 PropertyAccessor

  参数:

  pvs - PropertyValues to set on the target object

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't writable

  PropertyBatchUpdateException - if one or more PropertyAccessExceptions occurred for specific properties during the batch update. This exception bundles all individual PropertyAccessExceptions. All other properties will have been successfully updated.

  BeansException

• setPropertyValues

  public void setPropertyValues​(PropertyValues pvs,
                                boolean ignoreUnknown)
                         throws BeansException

  从接口复制的说明: PropertyAccessor
  Perform a batch update with more control over behavior.

  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.

  指定者:

  setPropertyValues 在接口中 PropertyAccessor

  参数:

  pvs - PropertyValues to set on the target object

  ignoreUnknown - should we ignore unknown properties (not found in the bean)

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't writable

  PropertyBatchUpdateException - if one or more PropertyAccessExceptions occurred for specific properties during the batch update. This exception bundles all individual PropertyAccessExceptions. All other properties will have been successfully updated.

  BeansException

• setPropertyValues

  public void setPropertyValues​(PropertyValues pvs,
                                boolean ignoreUnknown,
                                boolean ignoreInvalid)
                         throws BeansException

  从接口复制的说明: PropertyAccessor
  Perform a batch update with full control over behavior.

  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.

  指定者:

  setPropertyValues 在接口中 PropertyAccessor

  参数:

  pvs - PropertyValues to set on the target object

  ignoreUnknown - should we ignore unknown properties (not found in the bean)

  ignoreInvalid - should we ignore invalid properties (found but not accessible)

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't writable

  PropertyBatchUpdateException - if one or more PropertyAccessExceptions occurred for specific properties during the batch update. This exception bundles all individual PropertyAccessExceptions. All other properties will have been successfully updated.

• getPropertyType

  public Class<?> getPropertyType​(String propertyPath)

  从类复制的说明: PropertyEditorRegistrySupport
  Determine the property type for the given property path.

  Called by PropertyEditorRegistrySupport.findCustomEditor(java.lang.Class<?>, java.lang.String) if no required type has been specified, to be able to find a type-specific editor even if just given a property path.

  The default implementation always returns null. BeanWrapperImpl overrides this with the standard getPropertyType method as defined by the BeanWrapper interface.

  指定者:

  getPropertyType 在接口中 PropertyAccessor

  覆盖:

  getPropertyType 在类中 PropertyEditorRegistrySupport

  参数:

  propertyPath - the property path to determine the type for

  返回:

  the type of the property, or null if not determinable

  PropertyAccessor.getPropertyType(String)

  Actually get the value of a property.

  指定者:

  getPropertyValue 在接口中 PropertyAccessor

  参数:

  propertyName - name of the property to get the value of

  返回:

  the value of the property

  抛出:

  InvalidPropertyException - if there is no such property or if the property isn't readable

  PropertyAccessException - if the property was valid but the accessor method failed

  InvalidPropertyException - if there is no such property or if the property isn't readable

  PropertyAccessException - if the property was valid but the accessor method failed
