Interface Summary

Interface	Description
CloneableStream	This is a simple interface that is used by streams that can clone themselves.
ErrorInfo	Getting error information for SQLData/serializable data streams.
ErrorObjectInput	Limit and ObjectInput capabilities.
Formatable	Derby interface for creating a stored form for an object and re-constructing an equivalent object from this stored form.
Limit	Methods that allow limits to be placed on an input or output stream to avoid clients reading or writing too much information.
LimitObjectInput	Limit and ErrorObjectInput capabilities.
Storable	Formatable for holding SQL data (which may be null).
StoredFormatIds	A format id identifies a stored form of an object for the purposes of locating a class which can read the stored form and reconstruct the object using the java.io.Externalizable interface.
StreamStorable	Streaming interface for a data value.
TypedFormat	Derby interface for identifying the format id for the stored form of an object.

Class Summary

Class	Description
AccessibleByteArrayOutputStream	This allows us to get to the byte array to go back and edit contents or get the array without having a copy made.
ApplicationObjectInputStream	An object input stream that implements resolve class in order to load the class through the ClassFactory.loadApplicationClass method.
ArrayInputStream	An InputStream that allows reading from an array of bytes.
ArrayOutputStream
ArrayUtil	Utility class for constructing and reading and writing arrays from/to formatId streams and for performing other operations on arrays.
CloseFilterInputStream	A stream that will throw an exception if its methods are invoked after it has been closed.
CompressedNumber	Static methods to write and read compressed forms of numbers to DataOut and DataIn interfaces.
CounterOutputStream	An OutputStream that simply provides methods to count the number of bytes written to an underlying stream.
DataInputUtil	A util class for DataInput.
DebugByteTeeOutputStream
DynamicByteArrayOutputStream	A DynamicByteArrayOutputStream allows writing to a dynamically resizable array of bytes.
FileUtil	A set of public static methods for dealing with File objects.
FormatableArrayHolder	A formatable holder for an array of formatables.
FormatableBitSet	FormatableBitSet is implemented as a packed array of bytes.
FormatableHashtable	A formatable holder for a java.util.Hashtable.
FormatableInstanceGetter	Class that loads Formattables (typically from disk)through one level of indirection.
FormatableIntHolder	A formatable holder for an int.
FormatableLongHolder	A formatable holder for an long.
FormatableProperties	A formatable holder for a java.util.Properties.
FormatIdInputStream	A stream for reading objects with format id tags which was produced by a FormatIdOutputStream.
FormatIdOutputStream	A stream for serializing objects with format id tags.
FormatIdUtil	Utility class with static methods for constructing and reading the byte array representation of format id's.
InputStreamUtil	Utility methods for InputStream that are stand-ins for a small subset of DataInput methods.
LimitInputStream	An abstract InputStream that provides abstract methods to limit the range that can be read from the stream.
LimitReader	A Reader that provides methods to limit the range that can be read from the reader.
NullOutputStream	An OutputStream that simply discards all data written to it.
RegisteredFormatIds	Registration of TypedFormat classes.

Exception Summary

Exception	Description
DerbyIOException	A subclass of IOException that carries a SQL state.
SQLExceptionWrapper	Wrapper class for SQLExceptions
