compressedState	back to summary
private transient int compressedState Holds several boolean and enum typed attributes in a very compact manner. Enum values are stored in 4 bits (where 0 represents `null`, and each enum value is represented by its ordinal value + 1), thus allowing for up to 15 values per enum. Boolean values are stored in one bit. The value is structured as follows: 1 - Lock mode 2 - Status 3 - Previous Status 4 - existsInDatabase 5 - isBeingReplicated 6 - loadedWithLazyPropertiesUnfetched; NOTE: this is not updated when properties are fetched lazily! 0000 0000 \| 0000 0000 \| 0654 3333 \| 2222 1111 Use `setCompressedValue(org.hibernate.engine.internal.AbstractEntityEntry.EnumState, Enum)`, `getCompressedValue(org.hibernate.engine.internal.AbstractEntityEntry.EnumState)` etc to access the enums and booleans stored in this value. Representing enum values by their ordinal value is acceptable for our case as this value itself is never serialized or deserialized and thus is not affected should ordinal values change.

Holds several boolean and enum typed attributes in a very compact manner. Enum values are stored in 4 bits (where 0 represents null, and each enum value is represented by its ordinal value + 1), thus allowing for up to 15 values per enum. Boolean values are stored in one bit.

The value is structured as follows:

1 - Lock mode
2 - Status
3 - Previous Status
4 - existsInDatabase
5 - isBeingReplicated
6 - loadedWithLazyPropertiesUnfetched; NOTE: this is not updated when properties are fetched lazily!

0000 0000 | 0000 0000 | 0654 3333 | 2222 1111

Use setCompressedValue(org.hibernate.engine.internal.AbstractEntityEntry.EnumState, Enum), getCompressedValue(org.hibernate.engine.internal.AbstractEntityEntry.EnumState) etc to access the enums and booleans stored in this value.

Representing enum values by their ordinal value is acceptable for our case as this value itself is never serialized or deserialized and thus is not affected should ordinal values change.
