Module org.postgresql.pljava.internal

Package org.postgresql.pljava.internal

Java classes implementing core PL/Java behavior. Many of these are the concrete implementations of classes in the pljava-api module, and many have corresponding native code in pljava-so.

Class Summary

Class	Description
AclId	The AclId correspons to the internal PostgreSQL AclId.
Backend	Provides access to some useful routines in the PostgreSQL server.
ByteBufferInputStream	Wrap a readable ByteBuffer as an InputStream.
ByteBufferXMLReader	Wrap a readable ByteBuffer as a SyntheticXMLReader.
Checked.Closing<T,E extends Exception>	A class that can supply a T while also implementing AutoCloseable<E>; suitable for use in a try-with-resources to wrap some value that does not itself implement AutoCloseable.
Checked.OptionalBase	Head of a family of Optional-like types covering the Java primitives that the java.util.Optional... classes do not cover, and whose methods that expect functional interfaces will accept the checked-exception versions declared here.
Checked.OptionalBoolean	A container object which may or may not contain a boolean value.
Checked.OptionalByte	A container object which may or may not contain a byte value.
Checked.OptionalChar	A container object which may or may not contain a char value.
Checked.OptionalFloat	A container object which may or may not contain a float value.
Checked.OptionalShort	A container object which may or may not contain a short value.
DualState<T>	Base class for object state with corresponding Java and native components.
DualState.Key	Magic cookie needed as a constructor parameter to confirm that DualState subclass instances are being constructed from native code.
DualState.SingleFreeErrorData<T>	A DualState subclass whose only native resource releasing action needed is FreeErrorData of a single pointer.
DualState.SingleFreeTupleDesc<T>	A DualState subclass whose only native resource releasing action needed is FreeTupleDesc of a single pointer.
DualState.SingleGuardedLong<T>	A DualState subclass serving only to guard access to a single nonzero long value (typically a native pointer).
DualState.SingleHeapFreeTuple<T>	A DualState subclass whose only native resource releasing action needed is heap_freetuple of a single pointer.
DualState.SingleMemContextDelete<T>	A DualState subclass whose only native resource releasing action needed is MemoryContextDelete of a single context.
DualState.SinglePfree<T>	A DualState subclass whose only native resource releasing action needed is pfree of a single pointer.
DualState.SingleSPIcursorClose<T>	A DualState subclass whose only native resource releasing action needed is SPI_cursor_close of a single pointer.
DualState.SingleSPIfreeplan<T>	A DualState subclass whose only native resource releasing action needed is SPI_freeplan of a single pointer.
ErrorData	The ErrorData correspons to the ErrorData obtained using an internal PostgreSQL CopyErrorData call.
ExecutionPlan	The ExecutionPlan corresponds to the execution plan obtained using an internal PostgreSQL SPI_prepare call.
Function	Methods to look up a PL/Java function and prepare it for invocation.
InstallHelper	Group of methods intended to streamline the PL/Java installation/startup experience.
MarkableSequenceInputStream	Version of SequenceInputStream that supports mark and reset, to the extent its constituent input streams do.
MarkableSequenceInputStream.FetchingListIterator<E>	A ListIterator that will fetch an element from a BlockingQueue whenever hasNext would (otherwise) return false, adding it to the end of the list where the next next() will retrieve it.
MarkableSequenceReader	Like a MarkableSequenceInputStream but for characters.
Oid	The Oid correspons to the internal PostgreSQL Oid.
PgSavepoint	Implementation of Savepoint for the SPI connection.
Portal	The Portal correspons to the internal PostgreSQL Portal type.
Relation	The Relation correspons to the internal PostgreSQL Relation.
ResultSetPicker	An adapter class used internally when a set-returning user function returns a ResultSetHandle, presenting it as a ResultSetProvider instead.
Session	An instance of this interface reflects the current session.
SPI	The SPI class provides access to some global variables used by SPI.
SyntheticXMLReader	Base class implementing the tedious parts of a SAX XMLReader whose XML content is synthesized on the fly.
SyntheticXMLReader.EmptyAttributes2	An immutable and empty collection of attributes.
SyntheticXMLReader.FluentAttributes2	Subclass of Attributes2Impl that also provides chainable methods so attribute information can be supplied in a fluent style.
TransactionalMap	Deprecated, for removal: This API element is subject to removal in a future version. This class (a) isn't exposed in pljava-api, (b) is only used to implement the once-transactional attribute map in Session, and (c) hasn't had transactional behavior even there, since 3ab90e5 (November 2005).
TriggerData	The TriggerData correspons to the internal PostgreSQL TriggerData.
Tuple	The Tuple correspons to the internal PostgreSQL HeapTuple.
TupleDesc	The TupleDesc correspons to the internal PostgreSQL TupleDesc.
