static function this_type get_global_pool ()
Returns the singleton global pool for the item type, T.
This allows items to be shared amongst components throughout the verification environment.
static function T get_global ( KEY key )
Returns the specified item instance from the global item pool.
virtual function T get ( KEY key )
Returns the item with the given key.
If no item exists by that key, a new item is created with that key and returned.
virtual function void add ( KEY key, T item )
Adds the given (key, item) pair to the pool. If an item already exists at the given key it is overwritten with the new item.
virtual function int exists ( KEY key )
Returns 1 if a item with the given key exists in the pool, 0 otherwise.
virtual function int first ( ref KEY key )
Returns the key of the first item stored in the pool.
If the pool is empty, then key is unchanged and 0 is returned.
If the pool is not empty, then key is key of the first item and 1 is returned.
virtual function int last ( ref KEY key )
Returns the key of the last item stored in the pool.
If the pool is empty, then 0 is returned and key is unchanged.
If the pool is not empty, then key is set to the last key in the pool and 1 is returned.
virtual function int next ( ref KEY key )
Returns the key of the next item in the pool.
If the input key is the last key in the pool, then key is left unchanged and 0 is returned.
If a next key is found, then key is updated with that key and 1 is returned.
virtual function int prev ( ref KEY key )
Returns the key of the previous item in the pool.
If the input key is the first key in the pool, then key is left unchanged and 0 is returned.
If a previous key is found, then key is updated with that key and 1 is returned.
This provides a specialization of the generic uvm_pool #(KEY,T) class for an associative array of uvm_object-based objects indexed by string. Specializations of this class include the uvm_event_pool (a uvm_object_string_pool storing uvm_events) and uvm_barrier_pool (a uvm_obejct_string_pool storing uvm_barriers).

static function this_type get_global_pool ()
Returns the singleton global pool for the item type, T.
This allows items to be shared amongst components throughout the verification environment.
static function T get_global ( string key )
Returns the specified item instance from the global item pool.
virtual function T get ( string key )

Implements a class-based dynamic associative array.
class uvm_pool #( type KEY = int, T = uvm_void ) extends uvm_object
This provides a specialization of the generic uvm_pool #(KEY,T) class for an associative array of uvm_object-based objects indexed by string.
