AbstractHtmlElementTag
```
public abstract class AbstractDataBoundFormElementTag
extends AbstractFormTag
implements EditorAwareTag
```
Base tag for all data-binding aware JSP form tags.
Provides the common path and id properties. Provides sub-classes with utility methods for accessing the BindStatus of their bound value and also for interacting with the TagWriter.

  - NESTED_PATH_VARIABLE_NAME
```
protected static final String NESTED_PATH_VARIABLE_NAME

    Name of the exposed path variable within the scope of this tag: "nestedPath". Same value as NestedPathTag.NESTED_PATH_VARIABLE_NAME.

```

  - setPath
```
public void setPath(String path)
```
    Set the property path from the form object. May be a runtime expression.
  - getPath
```
protected final String getPath()
                        throws JspException
```
    Get the resolved property path for the form object.
    抛出:
    JspException
  - setId
```
public void setId(String id)
```
    Set the value of the 'id' attribute.
    May be a runtime expression; defaults to the value of getName(). Note that the default value may not be valid for certain tags.
    覆盖:
    setId 在类中 TagSupport
  - getId
```
public String getId()
```
    Get the value of the 'id' attribute.
    覆盖:
    getId 在类中 TagSupport
  - writeDefaultAttributes
```
protected void writeDefaultAttributes(TagWriter tagWriter)
                               throws JspException
```
    Writes the default set of attributes to the supplied TagWriter. Further abstract sub-classes should override this method to add in any additional default attributes but must remember to call the super method.
    Concrete sub-classes should call this method when/if they want to render default attributes.
    参数:
    tagWriter - the TagWriter to which any attributes are to be written
    抛出:
    JspException
  - resolveId
```
protected String resolveId()
                    throws JspException
```
    Determine the 'id' attribute value for this tag, autogenerating one if none specified.
    抛出:
    JspException
    另请参阅:
    getId(), autogenerateId()
  - autogenerateId
```
protected String autogenerateId()
                         throws JspException
```
    Autogenerate the 'id' attribute value for this tag.
    The default implementation simply delegates to getName(), deleting invalid characters (such as "[" or "]").
    抛出:
    JspException
  - getName
```
protected String getName()
                  throws JspException
```
    Get the value for the HTML 'name' attribute.
    The default implementation simply delegates to getPropertyPath() to use the property path as the name. For the most part this is desirable as it links with the server-side expectation for data binding. However, some subclasses may wish to change the value of the 'name' attribute without changing the bind path.
    返回:
    the value for the HTML 'name' attribute
    抛出:
    JspException
  - getBindStatus
```
protected BindStatus getBindStatus()
                            throws JspException
```
    Get the BindStatus for this tag.
    抛出:
    JspException
  - getNestedPath
```
protected String getNestedPath()
```
    Get the value of the nested path that may have been exposed by the NestedPathTag.
  - getPropertyPath
```
protected String getPropertyPath()
                          throws JspException
```
    Build the property path for this tag, including the nested path but not prefixed with the name of the form attribute.
    抛出:
    JspException
    另请参阅:
    getNestedPath(), getPath()
  - getBoundValue
```
protected final Object getBoundValue()
                              throws JspException
```
    Get the bound value.

  - getPropertyEditor
```
protected PropertyEditor getPropertyEditor()
                                    throws JspException
```
    Get the PropertyEditor, if any, in use for value bound to this tag.
    抛出:
    JspException
  - getEditor
```
public final PropertyEditor getEditor()
                               throws JspException
```
    Exposes the PropertyEditor for EditorAwareTag.
    Use getPropertyEditor() for internal rendering purposes.
    指定者:
    getEditor 在接口中 EditorAwareTag
    返回:
    the current PropertyEditor, or null if none
    抛出:
    JspException - if resolving the editor failed
  - convertToDisplayString
```
protected String convertToDisplayString(Object value)
                                 throws JspException
```
    Get a display String for the given value, converted by a PropertyEditor that the BindStatus may have registered for the value's Class.
    抛出:
    JspException
  - processFieldValue
```
protected final String processFieldValue(String name,

                                         String type)
```
    Process the given form field through a RequestDataValueProcessor instance if one is configured or otherwise returns the same value.
  - doFinally
```
public void doFinally()
```
    Disposes of the BindStatus instance.
