public final class ResourceContextFactory
extends Object
```
Deprecated, for removal: This API element is subject to removal in a future version.
Resource Management is deprecated for removal with no replacement.
The ResourceContextFactory provides access to ResourceContext functions. The factory provides methods to:
- Return the ResourceContextFactory instance and checks if the API is accessible to the caller
- Check if ResourceContexts are enabled
- Return a new ResourceContext
- Return a ResourceContext by name
- Return the ResourceContext bound to the current thread
- Return the UnassignedContext used for all unbound threads
- Return the TotalsContext that tracks totals of all contexts
- Return a Stream of the ResourceContexts
- Return the supported ResourceTypes
The getInstance method checks if there is a SecurityManager installed and the RuntimePermission("jdk.management.resource.getResourceContextFactory") is allowed. The reference to the ResourceContextFactory is a capability and should not be shared.
Threads that exist when the ResourceContextFactory is initialized are bound to the unassignedContext if they are not system threads. System threads ( with (thread.getThreadGroup().getParent() == null ) are not bound to the unassignedContext. The resources used by system threads are not recorded.

  - isEnabled
```
public static boolean isEnabled()
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns true if and only if ResourceManagement is enabled. Refer to supportedResourceTypes() for the set of resources available.
    
    Returns:
    
    true if and only if ResourceManagement is enabled; otherwise false
    
    Throws:
    
    SecurityException - if a SecurityManager is installed and the RuntimePermission("jdk.management.resource.getResourceContextFactory) is denied
  - getInstance
```
public static ResourceContextFactory getInstance()
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns the factory for ResourceContexts if enabled in the runtime.
    
    Returns:
    
    the factory for ResourceContexts
    
    Throws:
    
    SecurityException - if a SecurityManager is installed and the RuntimePermission("jdk.management.resource.getResourceContextFactory) is denied
  - create
```
public ResourceContext create(String name)
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Create a new ResourceContext. A new empty ResourceContext with the specified name is created. The names of ResourceContexts must be unique. Use close to dispose of a ResourceContext.
    
    Parameters:
    
    name - a name for the ResourceContext
    
    Returns:
    
    a new ResourceContext
    
    Throws:
    
    IllegalArgumentException - if a ResourceContext with the name already exists.
    
    UnsupportedOperationException - if the number of ResourceContexts exceeds implementation limits
  - lookup
```
public ResourceContext lookup(String name)
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns the ResourceContext given by name.
    
    Parameters:
    
    name - the name
    
    Returns:
    
    the ResourceContext given by name; null if there is no ResourceContext with the name
  - getThreadContext
```
public ResourceContext getThreadContext()
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns the ResourceContext associated with the current thread.
    
    Returns:
    
    the ResourceContext associated with the current thread; the unassigned context if the thread is not associated with any context
  - getThreadContext
```
public ResourceContext getThreadContext(Thread thread)
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns the ResourceContext associated with the thread.
    
    Parameters:
    
    thread - the thread to query
    
    Returns:
    
    the ResourceContext associated with the current thread; the unassigned context if the thread is not associated with any context
  - getResourceRequest
```
public ResourceRequest getResourceRequest(ResourceType type)
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns the ResourceRequest for the current ResourceContext and ResourceType. If there is no ResourceContext associated with the current thread, the unassigned context is used.
    
    Parameters:
    
    type - the ResourceType of the resource making the request
    
    Returns:
    
    a ResourceRequest; null if there is no ResourceMeter with the type in the ResourceContext

public ResourceContext getTotalsContext()
```
    Deprecated, for removal: This API element is subject to removal in a future version.
    
    Returns a ResourceContext that provides the totals for all ResourceContexts. The meters reflect the sum of all other ResourceContexts plus the final counts of removed ResourceContexts. These meters are read only and are only updated by changes to active ResourceContexts.
    
    Returns:
    
    the totals ResourceContext
  - contexts
