Lazy Loading Configuration#

Configuration management for lazy loading functionality.

This module provides configuration management for the lazy loading system, allowing users to customize behavior and persist settings.

LazyLoadingConfig([folder_scan_batch_size, ...])

Configuration for lazy loading behavior.

ConfigManager(*args, **kwargs)

Manager for lazy loading configuration.

get_config()

Get the current lazy loading configuration.

update_config(**kwargs)

Update the lazy loading configuration.
class mdaviz.lazy_loading_config.ConfigManager(*args: Any, **kwargs: Any)[source]#

Manager for lazy loading configuration.

This class manages the loading, saving, and updating of lazy loading configuration settings.

_load_config() → LazyLoadingConfig[source]#

Load configuration from file or create default.

config_changed#

alias of object

get_config() → LazyLoadingConfig[source]#

Get the current configuration.

get_memory_usage_mb() → float[source]#

Get current memory usage in megabytes.

Returns:

float: Memory usage in MB

is_memory_usage_high() → bool[source]#

Check if memory usage is above the warning threshold.

Returns:

bool: True if memory usage is high

reset_to_defaults() → bool[source]#

Reset configuration to default values.

Returns:

bool: True if successful, False otherwise

save_config(config: LazyLoadingConfig) → bool[source]#

Save configuration to file.

Parameters:

config (LazyLoadingConfig): Configuration to save

Returns:

bool: True if successful, False otherwise

update_config(**kwargs) → bool[source]#

Update configuration with new values.

Parameters:

**kwargs: Configuration values to update

Returns:

bool: True if successful, False otherwise

Configuration for lazy loading behavior.

This class contains all the configuration options for the lazy loading system, including cache sizes, batch sizes, and performance settings.

classmethod from_dict(data: dict[str, Any]) → LazyLoadingConfig[source]#

Create configuration from dictionary.

classmethod load_from_file(file_path: Path) → LazyLoadingConfig | None[source]#

Parameters:

file_path (Path): Path to load configuration from

Returns:

LazyLoadingConfig or None: Configuration if successful, None otherwise

save_to_file(file_path: Path) → bool[source]#

Save configuration to file.

Parameters:

file_path (Path): Path to save configuration

Returns:

bool: True if successful, False otherwise

to_dict() → dict[str, Any][source]#

Convert configuration to dictionary.

mdaviz.lazy_loading_config.get_config() → LazyLoadingConfig[source]#

Get the current lazy loading configuration.

Returns:

LazyLoadingConfig: Current configuration

mdaviz.lazy_loading_config.get_global_config_manager() → ConfigManager[source]#

Get the global configuration manager instance.

Returns:

ConfigManager: Global configuration manager

mdaviz.lazy_loading_config.update_config(**kwargs) → bool[source]#
