Migrate(MigrationContext)

Declaration
public void Migrate(MigrationContext context)
Parameters
Type Name Description
MigrationContext context

MigrateInstance(MigrationContext)

Migrates an instance with provided context. It may modify context with one of following migration results:

  • ReferenceTypeName != null means that binary content was fully consumed and a reference should be serialized instead. It should contains the referenced object id in ReferenceId;
  • Schema modified and output schema is a class schema, it means that original class binary data was replaced with another class binary data and it should use new object serializer;
  • Schema modified and output schema is the cached serializer schema, it means that original binary content was consumed and object instance created and cached for upcoming deserialization call;
  • Schema modified, but output schema not class or cached object, it means that Reader contains compatible binary data. If reader wasn't modified then it will be reset to initial position.
  • Schema not modified, if Reader modified then it should be re-serialized with original serializer or just reset reader position otherwise.
Declaration
public abstract void MigrateInstance(MigrationContext context)
Parameters

MigrationContext context

MigrateReference(MigrationContext)

Migrates an reference with provided context. It may modify context with one of following migration results:

  • Schema modified and output schema is a class schema, it means that original class binary data was replaced with another class binary data and it should use new object serializer;
  • Schema modified and output schema is the cached serializer schema, it means that original binary content was consumed and object instance created and cached for upcoming deserialization call;
  • Schema modified, but output schema not class or cached object, it means that Reader contains compatible binary data. If reader wasn't modified then it will be reset to initial position.
