The following shared getters are renamed so that their names are
distinct from the corresponding getters in the analyzer:
- `SharedFunctionTypeStructure.positionalParameterTypes` is renamed to
`positionalParameterTypesShared` to be distinct from the analyzer's
public getter `FunctionType.positionalParameterTypes`.*
- `SharedFunctionTypeStructure.returnType` is renamed to
`returnTypeShared` to be distinct from the analyzer's public getter
`FunctionType.returnType`.
- `SharedNamedFunctionParameterStructure.type` is renamed to
`typeShared` to be distinct from the analyzer's public getter
`FormalParameterElement.type`.
- `SharedNamedTypeStructure.type` is renamed to `typeShared` to be
distinct from the analyzer's public getter
`RecordTypeNamedField.type`.
- `SharedRecordTypeStructure.positionalTypes` is renamed to
`positionalTypesShared` to be distinct from the analyzer's public
getter `RecordType.positionalTypes`.*
- `SharedRecordTypeStructure.sortedNamedTypes` is renamed to
`sortedNamedTypesShared` to be distinct from the analyzer's public
getter `RecordType.sortedNamedTypes`.
- `SharedTypeParameterStructure.bound` is renamed to `boundShared` to
be distinct from the analyzer's public getter
`TypeParameterElement2.bound`.
*Note that `FunctionType.positionalParameterTypes`,
`RecordType.positionalTypes`, and `RecordType.sortedNamedTypes` were
unintentionally exposed as part of the analyzer's public API. In a
previous CL I marked them as deprecated.
These renames pave the way for changing the analyzer's `DartType`
class so that it implements `SharedTypeStructure<TypeImpl>` rather
than `SharedTypeStructure<DartType>` (without the renames, the public
getters mentioned above would all have to be changed to have type
`TypeImpl`, and that in turn would expose `TypeImpl` through the
analyzer public API, which we don't want to do).
Once `DartType` implements `SharedTypeStructure<TypeImpl>`, that will
allow all the other uses of `SharedTypeStructure<DartType>` in the
analyzer to be gradually migrated to
`SharedTypeStructure<TypeImpl>`. Once that is done, `DartType` can be
changed so that it no longer implements
`SharedTypeStructure<TypeImpl>` at all (`TypeImpl` will implement
`SharedTypeStructure<TypeImpl> instead). This will free us up to make
future changes to the `SharedTypeStructure` base class without
inadvertently exposing those changes through the analyzer public API.
This is part of a larger arc of work to change the analyzer's use of
the shared code so that the type parameters it supplies are not part
of the analyzer public API. See
