OfPatcherDefinition

In case when both object to patch and patch value contain field with a collection, this option allows to append value from patch to the source value, rather than overriding it.

By default, patch's collection overrides the content of a field.

When scala.Option is patching scala.Option, on scala.None value will be cleared.

Fail the compilation if there is a redundant field in patching object.

In case when both object to patch and patch value contain field of type scala.Either, this option allows to treat scala.Left value in patch as if the value was not provided.

By default, when scala.Left is delivered in patch, Chimney used this new value.

In case when both object to patch and patch value contain field of type scala.Option, this option allows to treat scala.None value in patch as if the value was not provided.

By default, when scala.None is delivered in patch, Chimney clears the value of such field on patching.

In case that patch object contains a redundant field (i.e. field that is not present in patched object type), this option enables ignoring value of such fields and generate patch successfully.

By default, when Chimney detects a redundant field in patch object, it fails the compilation in order to prevent silent oversight of field name typos.

When collection is patching collection, the value will be simply overriden.

When scala.Either is patching scala.Either, on scala.Left value will be overrides.
