Detailed Description

This module provides shared functionality for the system to generate
Dart:html APIs from the IDL database.

◆ _GetPromiseAttributeType()

scripts.systemhtml._GetPromiseAttributeType ( interface_operation )

protected

Definition at line 1251 of file systemhtml.py.

def _GetPromiseAttributeType(interface_operation):
    if interface_operation in promise_attributes:
        return promise_attributes[interface_operation]
    return None
 
# Compatibility is used to help determine attribute nullability i.e. if the
# attribute is not compatible across all browsers, the getter/setter is marked
# as nullable. There are cases where the attribute belongs to a class that
# implements an interface whose methods are not in the IDL, however.
# Since attribute getters need to match their overridden method declaration,
# there are conflicts when the overriding method is not compatible, the
# overriding method is, and they're not already nullable. This dict marks the
# attributes where there is a conflict that cannot be resolved with code
# generation or within src/template files.
