Implements: ReferencesDecorator
Description
The ManagedReferences class allows you to create managed references that in additon to keeping and locating references can also manage their lifecycle, such as:
- Auto-creation of missing components using available factories
- Auto-linking newly added components
- Auto-opening newly added components
- Auto-closing removed components
Constructors
NewManagedReferences
Creates a new instance of the decorator.
NewManagedReferences(ctx context.Context, tuples []any) *ManagedReferences
- ctx: context.Context - operation context.
- tuples: []any - tuples where odd values are component locators (descriptors) and even values are component references
NewEmptyManagedReferences
Creates a new instance of the references
NewEmptyManagedReferences() *ManagedReferences
NewEmptyManagedReferences
Creates a new instance of the references
NewEmptyManagedReferences() *ManagedReferences
NewManagedReferencesFromTuples
Removes all component references that match the specified locator.
NewManagedReferencesFromTuples(ctx context.Context, tuples …any) *ManagedReferences
- ctx: context.Context - operation cotext.
- locator: …any - locator to remove references by.
- returns: ManagedReferences - list containing all removed references.
Methods
Close
Closes the component and frees used resources.
(c *ManagedReferences) Close(ctx context.Context, context IContext) error
- ctx: context.Context - operation cotext.
- context: IContext - (optional) a context to trace execution through a call chain.
- retunrs: error - returns error if not closed
IsOpen
Checks if the component is open.
(c *ManagedReferences) IsOpen() bool
- returns: bool - True if the component is open and False otherwise.
Open
Opens the component.
(c *ManagedReferences) Open(ctx context.Context, context IContext) error
- ctx: context.Context - operation cotext.
- context: IContext - (optional) a context to trace execution through a call chain.
- returns: error - return error if not opened
