Class BinaryImporter

java.lang.Object
  com.threerings.export.Importer
      com.threerings.export.BinaryImporter

All Implemented Interfaces:: Closeable

public class BinaryImporter
extends Importer
extends Importer

Imports from the compact binary format generated by BinaryExporter.

Nested Class Summary
`protected class`	`BinaryImporter.ClassData` Contains information on an exportable class.
`protected class`	`BinaryImporter.ClassWrapper` Contains information on a class in the stream, which may or may not be resolvable.
`protected class`	`BinaryImporter.IDReader` Reads in integer identifiers using a width that depends on the highest value read so far.

Field Summary
`protected InputStream`	`_base` The underlying input stream.
`protected HashMap<BinaryImporter.ClassWrapper,BinaryImporter.ClassData>`	`_classData` Class
`protected HashIntMap<BinaryImporter.ClassWrapper>`	`_classes` Maps ids to classes read.
`protected BinaryImporter.IDReader`	`_classIdReader` Used to read class ids.
`protected HashMap<String,Object>`	`_fields` Field values associated with the current object.
`protected DataInputStream`	`_in` The stream that we use for reading data.
`protected BinaryImporter.ClassWrapper`	`_objectClass` The wrapper for the object class.
`protected BinaryImporter.IDReader`	`_objectIdReader` Used to read object ids.
`protected HashIntMap<Object>`	`_objects` Maps ids to objects read.
`protected BinaryImporter.ClassWrapper`	`_stringClass` The wrapper for the String class.
`protected HashMap<Class<?>,BinaryImporter.ClassWrapper>`	`_wrappersByClass` Maps class objects to wrapper objects (for classes identified by reference).
`protected HashMap<String,BinaryImporter.ClassWrapper>`	`_wrappersByName` Maps class names to wrapper objects (for classes identified in the stream).
`protected static Object`	`NULL` Signifies a null entry in the object map.

Fields inherited from class com.threerings.export.Importer
`_marshaller, _object`

`BinaryImporter(InputStream in)` Creates an importer to read from the specified stream.

_wrappersByClass

protected HashMap<Class<?>,BinaryImporter.ClassWrapper> _wrappersByClass

Maps class objects to wrapper objects (for classes identified by reference).

_objectClass

protected BinaryImporter.ClassWrapper _objectClass

The wrapper for the object class.

_stringClass

protected BinaryImporter.ClassWrapper _stringClass

The wrapper for the String class.

_classes

protected HashIntMap<BinaryImporter.ClassWrapper> _classes
