Class <Type> PolarisAliasField

A field that can be used to alias one key to another key present in the cache version of the resource.

Unlike DerivedField, an AliasField may write to its source when a record is in an editable mode.

AliasFields may utilize a transform, specified by type, to pre/post process the field.

An AliasField may also specify a kind via options. kind may be any other valid field kind other than

• @hash
• @id
• @local
• derived

This allows an AliasField to rename any field in the cache.

Alias fields are generally intended to be used to support migrating between different schemas, though there are times where they are useful as a form of advanced derivation when used with a transform. For instance, an AliasField could be used to expose both a string and a Date version of the same field, with both being capable of being written to.
