ObjectCache class

A simple cache of objects, where is possible to define different instantiators for each key.

Constructors

ObjectCache([int? maxInstances])

Properties

hashCode → int

The hash code for this object.

no setter, inherited

maxInstances ↔ int?

Maximum number of cached instances.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

clear() → void

Clear all cached instances and all definitions.

clearInstances() → void

Removes all cached instances, preseving definitions.

define<O>(String key, O instantiator(), [bool cacheValidator(Object o)?]) → void

Defines instantiator and cache-validator for key.

defineAll(Map<String, dynamic> map) → void

Define all keys from map, where map values can be a instantiator functions or a list with 2 values (instantiator and cache-validator functions).

disposeInstance(String key) → void

Removes key instance from cache.

disposeInstances(int? amountToRemove) → int

get<O>(String key, [O instantiator()?, bool cacheValidator(Object o)?]) → O?

Returns an object for key.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

setCacheValidator<O>(String key, bool cacheValidator(Object o)) → void

Sets the cacheValidator for key

setInstantiator<O>(String key, O instantiator()) → void

Sets the instantiator for key

toString() → String

A string representation of this object.

inherited

undefine<O>(String key) → void

Remove instantiator and cache-validator for key.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

operator [](String key) → dynamic
