com.sleepycat.persist.impl.ObjectArrayFormat
public class ObjectArrayFormat
An array of objects having a specified number of dimensions. All
multidimensional arrays are handled by this class, since even a primitive
array of more than one dimension is an array of objects, where the component
objects may be primitive arrays. The PrimitiveArrayFormat
class
handles primitive arrays of one dimension only.
In this class, and PrimitiveArrayFormat
, we resort to using
reflection to allocate multidimensional arrays. If there is a need for it,
reflection could be avoided in the future by generating code as new array
formats are encountered.

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. |
boolean |
isArray()
Returns whether this is an array type. |

newInstance(EntityInput input,
boolean rawAccess)
Creates a new instance of the target class using its default constructor. |
java.lang.Object |
readObject(java.lang.Object o,
EntityInput input,

instances.
If true is returned, the array component type is returned by RawType.getComponentType()
and the number of array dimensions is returned by
RawType.getDimensions()
.
If false is returned, then this is a complex type, an enum type (see
RawType.isEnum()
), or a simple type (see RawType.isSimple()
).
