io.permazen (Permazen 4.1.9 API)

Interface Summary
Interface	Description
JFieldSwitch<R>	Visitor pattern interface for `JField`s.
JObject	Interface implemented by `Permazen` Java model objects.
Session.Action	Callback interface used by `Session.performSessionAction()` and `Session.performSessionActionWithCurrentTransaction()`.
Session.HasTransactionOptions	Interface implemented by `Session.TransactionalAction`'s that want to provide custom transaction options.
Session.RetryableAction	Tagging interface indicating a `Session.TransactionalAction` that should be retried if a `RetryTransactionException` is thrown.
Session.TransactionalAction	Tagging interface indicating an `Session.Action` that requires there to be an open transaction.
StorageIdGenerator	Used to auto-generate storage ID's for Java model classes, fields, and composite indexes when not specified explicitly in the corresponding `@PermazenType`, `@JField`, etc., annotations.
UniquenessConstraints	JSR 303 validation group for Permazen uniqueness constraints.

Class Summary
Class	Description
CopyState	Maintains state about a multi-object copy operation.
Counter	Represents a 64-bit counter value that can be adjusted concurrently by multiple transactions, typically without locking (depending on the underlying key/value store).
DefaultStorageIdGenerator	Default `StorageIdGenerator` implementation.
EnumConverter<T extends Enum<T>>	Converts between core database `EnumValue` objects and the corresponding Java `Enum` model values.
ExportContext	Context for exporting plain (POJO) objects from a `JTransaction`.
ImportContext	Context for importing plain (POJO) objects into a `JTransaction`.
JClass<T>	Information about a Java class that is used to represent a specific Permazen object type.
JCollectionField	Represents a collection field in a `JClass`.
JComplexField	Represents a complex field in a `JClass`.
JCompositeIndex	A composite index.
JCounterField	Represents a counter field in a `JClass`.
JEnumArrayField	Represents an `Enum` array field in a `JClass`.
JEnumField	Represents an `Enum` field in a `JClass`.
JField	Represents a field in a Java model object.
JFieldSwitchAdapter<R>	Adapter class for `JFieldSwitch`.
JListField	Represents a list field in a `JClass`.
JMapField	Represents a map field in a `JClass`.
JReferenceField	Represents a reference field in a `JClass` or a reference sub-field of a complex field in a `JClass`.
JSchemaObject	Superclass for the `JClass` and `JField` classes which define the schema associated with a `Permazen`.
JSetField	Represents a set field in a `JClass`.
JSimpleField	Represents a simple field in a `JClass` or a simple sub-field of a complex field in a `JClass`.
JTransaction	A transaction associated with a `Permazen` instance.
Permazen	Permazen Java persistence layer.
PermazenFactory	Factory for `Permazen` instances.
ReferencePath	Reference paths.
Session	Utility class for programmatic `Permazen` database access.
SnapshotJTransaction	An in-memory `JTransaction` that persists indefinitely.
UntypedJObject	Represents a `JObject` for which no Java model type is defined in the instance's associated schema version.
Util	Various utility routines.
Version	Contains Permazen library version information.

Enum Summary
Enum	Description
SessionMode	`Session` modes.
UpgradeConversionPolicy	Policies to apply when a simple or counter field's type changes during a schema update.
ValidationMode	Configures whether and how objects are enqueued for validation in a `JTransaction`.

Exception Summary
Exception	Description
PermazenException	Superclass of all unchecked exceptions thrown by the `Permazen` API.
UpgradeConversionException	Exception thrown when an object is upgraded, some simple field's type changes, the field is configured with `UpgradeConversionPolicy.REQUIRE`, and automated conversion of the field's value to the new type fails.
ValidationException	Thrown when `JTransaction.validate()` (or `JTransaction.commit()`) fails due to one or more validation errors.
