AbstractErrors (spring-context 5.0.15.BUILD-SNAPSHOT API)

java.lang.Object
- org.springframework.validation.AbstractErrors

所有已实现的接口:

Serializable, Errors

直接已知子类:

AbstractBindingResult
```
public abstract class AbstractErrors
extends Object
implements Errors, Serializable
```
Abstract implementation of the Errors interface. Provides common access to evaluated errors; however, does not define concrete management of ObjectErrors and FieldErrors.

从以下版本开始:

2.5.3

  - setNestedPath
```
public void setNestedPath(@Nullable
                          String nestedPath)
```
    从接口复制的说明: Errors
    
    Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.
    For example, an address validator could validate the subobject "address" of a customer object.
    
    指定者:
    
    setNestedPath 在接口中 Errors
    
    参数:
    
    nestedPath - nested path within this object, e.g. "address" (defaults to "", null is also acceptable). Can end with a dot: both "address" and "address." are valid.
  - getNestedPath
```
public String getNestedPath()
```
    从接口复制的说明: Errors
    
    Return the current nested path of this Errors object.
    Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.
    
    指定者:
    
    getNestedPath 在接口中 Errors
  - pushNestedPath
```
public void pushNestedPath(String subPath)
```
    从接口复制的说明: Errors
    
    Push the given sub path onto the nested path stack.
    A Errors.popNestedPath() call will reset the original nested path before the corresponding pushNestedPath(String) call.
    Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.
    For example: current path "spouse.", pushNestedPath("child") -> result path "spouse.child."; popNestedPath() -> "spouse." again.
    
    指定者:
    
    pushNestedPath 在接口中 Errors
    
    参数:
    
    subPath - the sub path to push onto the nested path stack
    
    另请参阅:
    
    Errors.popNestedPath()
  - popNestedPath
```
public void popNestedPath()
                   throws IllegalStateException
```
    从接口复制的说明: Errors
    
    Pop the former nested path from the nested path stack.
    
    指定者:
    
    popNestedPath 在接口中 Errors
    
    抛出:
    
    IllegalStateException - if there is no former nested path on the stack
    
    另请参阅:
    
    Errors.pushNestedPath(java.lang.String)
  - doSetNestedPath
```
protected void doSetNestedPath(@Nullable
                               String nestedPath)
```
    Actually set the nested path. Delegated to by setNestedPath and pushNestedPath.
  - fixedField
```
protected String fixedField(@Nullable
                            String field)
```
    Transform the given field into its full path, regarding the nested path of this instance.
  - canonicalFieldName
```
protected String canonicalFieldName(String field)
```
    Determine the canonical field name for the given field.
    The default implementation simply returns the field name as-is.
    
    参数:
    
    field - the original field name
    
    返回:
    
    the canonical field name
  - reject

```

```
    从接口复制的说明: Errors
    
    Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.
