Interface Summary

Interface	Description
AbstractCursor.Getter	Gets a value from a particular field of the current record of this cursor.
ArrayImpl.Factory	Factory that can create a ResultSet or Array based on a stream of values.
Cursor	Interface to an iteration that is similar to, and can easily support, a JDBC ResultSet, but is simpler to implement.
Cursor.Accessor	Accessor of a column value.
Source	Source of data.
StructImpl.Factory	Factory that can create a result set based on a list of values.

Class Summary

Class	Description
AbstractCursor	Base class for implementing a cursor.
AbstractCursor.ArrayAccessor	Accessor that assumes that the underlying value is an ARRAY; corresponds to Types.ARRAY.
ArrayFactoryImpl	Implementation of ArrayImpl.Factory.
ArrayImpl	Implementation of JDBC Array.
ArrayIteratorCursor	Implementation of Cursor on top of an Iterator that returns an array of Object for each row.
Base64	Encodes and decodes to and from Base64 notation.
Base64.InputStream	A Base64.InputStream will read data from another java.io.InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
Base64.OutputStream	A Base64.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
ByteString	Collection of bytes.
DateTimeUtils	Utility functions for datetime types: date, time, timestamp.
DateTimeUtils.PrecisionTime	Helper class for DateTimeUtils.parsePrecisionDateTimeLiteral(java.lang.String, java.lang.String, java.util.TimeZone)
FilteredConstants	A class which, at build time, will have build-specific variables substituted into it.
IteratorCursor<E>	Implementation of Cursor on top of an Iterator that returns a record for each row.
ListIteratorCursor	Implementation of Cursor on top of an Iterator that returns a List for each row.
MapIteratorCursor	Implementation of Cursor on top of an Iterator that returns a Map for each row.
PositionedCursor<T>	Abstract implementation of Cursor that caches its current row.
RecordIteratorCursor<E>	Implementation of Cursor on top of an Iterator that returns a record for each row.
SecurityUtils	This class is loosely based on SecurityUtils in Jetty 12.0
Sources	Utilities for Source.
Spacer	Efficiently writes strings of spaces.
Spaces	Utilities for creating strings of spaces.
StructImpl	Implementation of JDBC Struct.
Unsafe	Contains methods that call JDK methods that the forbidden APIs checker does not approve of.
UnsynchronizedBuffer	A utility class for reading and writing bytes to byte buffers without synchronization.

Enum Summary

Enum	Description
Casing	Policy for converting case of identifiers before storing them.
Quoting	Syntax for quoting identifiers in SQL statements.
TimeUnit	Enumeration of time units used to construct an interval.
TimeUnitRange	A range of time units.
