org.apache.velocity.tools.Toolbox

所有已实现的接口:

Serializable

public class Toolbox
extends Object
implements Serializable

Instances of this class are typically created by a ToolboxFactory on a one-per-scope basis. So, for each application, there would be one application-scoped Toolbox from which you would retrieve tool instances, and for each request, there would be one request-scoped Toolbox. Of course, none of the above is enforced. There's no reason that you can't manually create a Toolbox or have multiple Toolboxes for each scope.

When a Toolbox creates a tool instance asked of it (see get(java.lang.String)), it will cache that instance for future requests.

public Map<String,Object> getProperties()

public Object get(String key,
 String path)

 Map<String,Object> context)

getFromCache

protected Object getFromCache(String key,
 String path)

getFromInfo

protected Object getFromInfo(String key,

 Map<String,Object> context)

hasPermission

protected boolean hasPermission(ToolInfo info,
 String path)

getKeys

public Set<String> getKeys()

getToolClassMap

public Map<String,Class> getToolClassMap()

Return a new Map link tools' keys to their Classes. This will not instantiate any tools, it is merely informational. This will not include the keys for any cached data. Note that inclusion in this map does NOT mean that all these tools will be available for all requests, as this map ignores all path restrictions on the tools.

返回:

a map of tools classes indexed by key

getAll

public Map<String,Object> getAll(Map<String,Object> context)

combine

public Toolbox combine(Toolbox... toolboxes)

Returns a new Toolbox that is a combination of this Toolbox with one or more specified Toolboxes. Neither this instance nor those specified are modified.

参数:

toolboxes - Toolboxes to combine

返回:

the combined toolbox
