pysepal.solara.session_manager.SessionManager#

class pysepal.solara.session_manager.SessionManager[source]#

A singleton session manager for solara-sepal applications.

This class manages the lifecycle of sessions across different Solara applications, providing a centralized way to handle session creation, retrieval, and cleanup for GEE interfaces, SepalClient and GDriveInterface.

Note: Do not instantiate this class directly. Use the @with_sepal_sessions decorator or the utility functions in sepal_ui.solara.utils instead.

Initialize the SessionManager singleton instance.

Methods

`__init__`	Initialize the SessionManager singleton instance.
`cleanup_session`	Clean up a session for the given kernel ID.
`create_session`	Create a new session with all the interfaces for the given kernel ID.
`get_kernel_id`	Get the current kernel ID.
`get_session_component`	Get a specific component from a session.
`get_session_info`	Get session information for a specific kernel.
`is_initialized`	Check if the SessionManager has been initialized.
`list_sessions`	Get all active sessions.

SessionManager.__init__()[source]#: Initialize the SessionManager singleton instance.

SessionManager.cleanup_session(kernel_id)[source]#

Clean up a session for the given kernel ID.

Parameters:: kernel_id (str) – The kernel ID to clean up.
Return type:: None

SessionManager.create_session(module_name='default')[source]#

Create a new session with all the interfaces for the given kernel ID.

Parameters:

kernel_id – The kernel ID to create session for. If None, uses current kernel.

Return type:: str

SessionManager.get_session_component(component_name, kernel_id=None)[source]#

Get a specific component from a session.

Parameters:

component_name (str) – The name/key of the component to retrieve.
kernel_id (str | None) – The kernel ID to get component from. If None, uses current kernel.

Returns:

The component instance or None if not found.

Return type:

Any | None

SessionManager.get_session_info(kernel_id=None)[source]#

Get session information for a specific kernel.

Parameters:: kernel_id (str | None) – The kernel ID to get info for. If None, uses current kernel.
Returns:: Dictionary with session information.
Return type:: dict

classmethod SessionManager.is_initialized()[source]#

Check if the SessionManager has been initialized.

Return type:: bool

SessionManager.list_sessions()[source]#

Get all active sessions.

Return type:: Dict[str, Dict[str, Any]]
