Systems and methods for updating subsets of elements of electronic documents

A system for updating properties of an element of an electronic document, comprising:

• a memory;
• and
• a processor, coupled to the memory, to:
• store, in a data store, a plurality of associations between types of mutations, mutation locations, and subsets of the element to update, at least one of the subsets specifying items of the element to update based on predefined locations of the items relative to the mutation locations;
• receive a mutation to the element;
• determine a type of the mutation, and a location of the mutation;
• retrieve from the data store, one or more associations of the plurality of associations, the retrieved one or more associations pertaining to the determined type of the mutation and the determined location of the mutation;
• determine, based on the retrieved one or more associations, a subset of the element to update, wherein the determined subset of the element specifies items of the element to update according to predefined locations of the specified items relative to the determined location of the mutation;
• and
• update the element by updating the determined subset.

A non-transitory computer-readable medium comprising instructions for updating properties of an element of an electronic document, which when executed by a processor, cause the processor to perform operations comprising:

• storing, in a data store, a plurality of associations between types of mutations, mutation locations, and subsets of the element to update, at least one of the subsets specifying items of the element to update based on predefined locations of the items relative to the mutation locations;
• receiving a mutation to the element;
• determining a type of the mutation, and a location of the mutation;
• retrieving from the data store, one or more associations of the plurality of associations, the retrieved one or more associations pertaining to the determined type of the mutation and the determined location of the mutation;
• determining based on the retrieved one or more associations, a subset of the element to update, wherein the determined subset of the element specifies items of the element to update according to predefined locations of the specified items relative to the determined location of the mutation;
• and
• updating the element by updating the determined subset.
