## com.sleepycat.persist.raw
Interface RawType

    public interface RawType

The type definition for a simple or complex persistent type, or an array of persistent types.

`RawType` objects are thread-safe. Multiple threads may safely call the methods of a shared `RawType` object.

Method Summary
`ClassMetadata` | `getClassMetadata()` Returns the original model class metadata used to create this class, or null if this is not a model class.
`String` | `getClassName()` Returns the class name for this type in the format specified by `Class.getName()`.
`RawType` | `getComponentType()` Returns the array component type, or null if this is not an array type.
`int` | `getDimensions()` Returns the number of array dimensions, or zero if this is not an array type.
`EntityMetadata` | `getEntityMetadata()` Returns the original model entity metadata used to create this class, or null if this is not an entity class.
`List<String>` | `getEnumConstants()` Returns an unmodifiable list of the names of the enum instances, or null if this is not an enum type.
`Map<String,RawField>` | `getFields()` Returns a map of field name to raw field for each non-static non-transient field declared in this class, or null if this is not a complex type (in other words, this is a simple type or an array type).
`int` | `getId()` Returns the internal unique ID for this type.
`RawType` | `getSuperType()` Returns the type of the superclass, or null if the superclass is Object or this is not a complex type (in other words, this is a simple type or an array type).
`int` | `getVersion()` Returns the class version for this type.
`boolean` | `isArray()` Returns whether this is an array type.
`boolean` | `isDeleted()` Returns whether this type has been deleted using a class `Deleter` mutation.
`boolean` | `isEnum()` Returns whether this is an enum type.
`boolean` | `isPrimitive()` Returns whether this type is a Java primitive: char, byte, short, int, long, float or double.
`boolean` | `isSimple()` Returns whether this is a simple type: primitive, primitive wrapper, BigInteger, String or Date.
`String` | `toString()` Returns an XML representation of the raw type.

Method Detail

### getClassName

    String getClassName()

  Returns the class name for this type in the format specified by `Class.getName()`.

  If this class currently exists (has not been removed or renamed) then the class name may be passed to `Class.forName(java.lang.String)` to get the current `Class` object. However, if this raw type is not the current version of the class, this type information may differ from that of the current `Class`.

### getVersion

    int getVersion()

  Returns the class version for this type. For simple types, zero is always returned.

  See Also:
    `Entity.version()`, `Persistent.version()`

### getId

    int getId()

  Returns the internal unique ID for this type.

### isSimple

    boolean isSimple()

  Returns whether this is a simple type: primitive, primitive wrapper, BigInteger, String or Date.

  If true is returned, `isPrimitive()` can be called for more information, and a raw value of this type is represented as a simple type object (not as a `RawObject`).

  If false is returned, this is a complex type, an array type (see `isArray()`), or an enum type, and a raw value of this type is represented as a `RawObject`.

### isPrimitive

    boolean isPrimitive()

  Returns whether this type is a Java primitive: char, byte, short, int, long, float or double.

  If true is returned, this is also a simple type. In other words, primitive types are a subset of simple types.

  If true is returned, a raw value of this type is represented as a non-null instance of the primitive type's wrapper class. For example, an `int` raw value is represented as an `Integer`.

### isEnum

    boolean isEnum()

  Returns whether this is an enum type.

  If true is returned, a value of this type is a `RawObject` and the enum constant String is available via `RawObject.getEnum()`.

  If false is returned, then this is a complex type, an array type (see `isArray()`), or a simple type (see `isSimple()`).

### getEnumConstants

    List<String> getEnumConstants()

  Returns an unmodifiable list of the names of the enum instances, or null if this is not an enum type.

### isArray

    boolean isArray()

  Returns whether this is an array type. Raw value arrays are represented as `RawObject` instances.

  If true is returned, the array component type is returned by `getComponentType()` and the number of array dimensions is returned by `getDimensions()`.

  If false is returned, then this is a complex type, an enum type (see `isEnum()`), or a simple type (see `isSimple()`).

### getDimensions

    int getDimensions()

  Returns the number of array dimensions, or zero if this is not an array type.

### getComponentType

    RawType getComponentType()

  Returns the array component type, or null if this is not an array type.

### getFields

    Map<String,RawField> getFields()

  Returns a map of field name to raw field for each non-static non-transient field declared in this class, or null if this is not a complex type (in other words, this is a simple type or an array type).

### getSuperType

    RawType getSuperType()

  Returns the type of the superclass, or null if the superclass is Object or this is not a complex type (in other words, this is a simple type or an array type).

### getClassMetadata

    ClassMetadata getClassMetadata()

  Returns the original model class metadata used to create this class, or null if this is not a model class.

### getEntityMetadata

    EntityMetadata getEntityMetadata()

  Returns the original model entity metadata used to create this class, or null if this is not an entity class.

### isDeleted

    boolean isDeleted()

  Returns whether this type has been deleted using a class `Deleter` mutation. A deleted type may be returned by `EntityModel.getRawTypeVersion` or `EntityModel.getAllRawTypeVersions`.

### toString

    String toString()

  Returns an XML representation of the raw type.

  Overrides:
    `toString` in class `Object`
