Returns a child model where ShareDB operations are always composed.
Returns a ChildModel scoped to the root path.
Returns a ChildModel scoped to a relative subpath under this model's path.
Creates a new child model with a specific named data-loading context. The child model has the same scoped path as this model.
Contexts are used to track counts of fetches and subscribes, so that all data relating to a context can be unloaded all at once, without having to manually track loaded data.
Contexts are in a global namespace for each root model, so calling
model.context(contextId) from two different places will return child
models that both refer to the same context.

Optionalsubpath: PathCall the function with the values at the input paths, returning the value
on completion. Unlike start, this only occurs once and does not create
a listener for updating based on changes.
The function should be a pure function - it should always return the same result given the same inputs, and it should be side-effect free.

Creates a live-updating list from items in an object, which results in automatically updating as the input items change.
Path pointing to an object or array. The path's value is retrieved via model.get(), and each item checked against filter function
Other parameters can be set in the model, and the filter function will be re-evaluated when these parameters change as well.

A function or the name of a function defined via model.fn(). The function should have the arguments function(item, key, object, additionalInputs...)
Gets the value located at this model's path.
If no value exists at the path, this returns undefined.
Note: The value is returned by reference, and object values should not be directly modified - use the Model mutator methods instead. The TypeScript compiler will enforce no direct modifications, but there are no runtime guards, which means JavaScript source code could still improperly make direct modifications.

Gets the value located at this model's path or a relative subpath.
If no value exists at the path, or the value is nullish (null or undefined), this will throw an error.

Optionalcb: ErrorCallbackOptionalcb: ErrorCallbackOptionalcb: ErrorCallbackOptionalcb: ErrorCallbackListen to Racer events matching a certain path or path pattern.
pathPattern is a path pattern that will filter emitted events, calling
the handler function only when a mutator matches the pattern.
Path patterns support a single segment wildcard '*' anywhere in a path,
and a multi-segment wildcard '**' at the end of the path. The
multi-segment wildcard alone '**' matches all paths.
Examples of path patterns:
'notes.abc-123.author' - Trigger on a direct modification to a
specific note's author. Will not trigger if a sub-property of the
author is modified or if the entire note is replaced.notes.*.author - Trigger on a direct modification to any note's
author. Will not trigger if a sub-property of the author is modified
or if an entire note is replaced.notes.*.author.** - Trigger on a modification to any note's author
or any sub-property of author. Will not trigger if an entire note is
replaced.Listen to Racer events matching a certain path or path pattern, removing the listener after it gets triggered once.

Sets the array value at this model's path or a relative subpath, based on a deep equality comparison between array items.
This only issues array insert, remove, and move operations. Unlike

items.

Sets the value at this model's path or a relative subpath, if different

Sets the value at this model's path or a relative subpath, if different from the current value based on a recursive deep equal comparison.
