方法详细资料

setAttribute

public void setAttribute(String name,
 @Nullable
 Object value)

从接口复制的说明: WebSession

Binds an object to this session, using the name specified. If an object of the same name is already bound to the session, the object is replaced.

After this method executes, and if the new object implements AttributeBindingListener, the container calls AttributeBindingListener.valueBound. The container then notifies any HttpSessionAttributeListeners in the web application.

If an object was already bound to this session of this name that implements AttributeBindingListener, its AttributeBindingListener.valueUnbound method is called.

If the value passed in is null, this has the same effect as calling removeAttribute().

指定者:

setAttribute 在接口中 WebSession

参数:

name - the name to which the object is bound; cannot be null

value - the object to be bound

attributeBinding

protected boolean attributeBinding(Object value,
 @Nullable
 Object oldValue)

allowAttributeReplaced

protected boolean allowAttributeReplaced(Object value,
 @Nullable
 Object oldValue)

attributeAdded

protected void attributeAdded(String name,
 Object value)

attributeReplaced

protected void attributeReplaced(String name,
 Object oldValue,
 Object value)

attributeRemoved

protected void attributeRemoved(String name,
 Object attribute)

getAttribute

@Nullable
public Object getAttribute(String name)

从接口复制的说明: WebSession

Returns the object bound with the specified name in this session, or null if no object is bound under the name.

指定者:

getAttribute 在接口中 WebSession

参数:

name - a string specifying the name of the object

返回:

the object with the specified name

removeAttribute

public Object removeAttribute(String name)

从接口复制的说明: WebSession

Removes the object bound with the specified name from this session. If the session does not have an object bound with the specified name, this method does nothing.

After this method executes, and if the object implements AttributeBindingListener, the container calls AttributeBindingListener.valueUnbound . The container then notifies any WebSessionAttributeListeners in the web application.

指定者:

removeAttribute 在接口中 WebSession

参数:

name - the name of the object to remove from this session

invalidate

public void invalidate()

从接口复制的说明: WebSession

Invalidate the current session and clear session storage.

指定者:

invalidate 在接口中 WebSession

doInvalidate

protected void doInvalidate()

hasAttribute

public boolean hasAttribute(String name)

从接口复制的说明: WebSession

Return true if the attribute identified by name exists. Otherwise return false.

指定者:

hasAttribute 在接口中 WebSession

参数:

name - the unique attribute key

getAttributeNames

public String[] getAttributeNames()

从接口复制的说明: WebSession

Return the names of all attributes.

指定者:

getAttributeNames 在接口中 WebSession

attributeNames

public Iterator<String> attributeNames()

从接口复制的说明: WebSession

Return the names Iterator.

指定者:

attributeNames 在接口中 WebSession

copyAttributesFrom

protected final void copyAttributesFrom(WebSession source)

Copy the attributes from the supplied AttributeAccessor to this accessor.

参数:

source - the AttributeAccessor to copy from

hasAttributes

public boolean hasAttributes()

Returns true if this map contains no key-value mappings.

指定者:

hasAttributes 在接口中 WebSession

返回:

true if this map contains no key-value mappings

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

getAttributes

public Map<String,Object> getAttributes()

从接口复制的说明: WebSession

Return attributes map

指定者:

getAttributes 在接口中 WebSession

返回:

attributes map

createAttributes

protected Map<String,Object> createAttributes()
