ConsoleLineStatus |
Need for setting connection of Session's LineStatuses with
the System.out standard output stream. |

Error |
An object that provides information if Session analysis
completes with Errors. |
Failure |
An object that provides information if Session execution
completes with failure. |
LineStatus |
A tool for logging a Session's Status namely a current
Script line or a out data line. |
Script |
Can be executed many times for different Z databases or Z multitudes
of a Session. |
Session |
Is a central object of Sav Z API, provides connection with Z databases,
Z multitude variables, Printer and Status objects. |
Statement |
An object that represents a Z statement and forms a Script. |
Status |
A tool for logging a Session's status namely a current process or Z database. |
Warning |
An object that provides information if Session process, analysis/execution,
completes with Warnings: Errors or Failures. |
WLineStatus |
Prints Session's current scriptline/dataline to
a PrintWriter . |
WPrinter |
Prints Session's report and messages to
a PrintWriter . |
WStatus |
Prints Session's current process/database to
a PrintWriter . |
Provides "Sav Z API" for analyzing and executing Z language Scripts.
Z algebraic expressions reflect peculiarities of Z ORDBMS,
for example, multilevel classification, dynamic structure, inheritance,
many-valued data, and manipulation with multitudes of the class
or relation objects.
The advantages of Z over SQL makes an impact on advantages of Sav Z API
over JDBC. Furthermore,
the multitude variables enables formalize easily a work with objects
from a few databases simultaneously.
Z Script combines many Statements, it makes Java program more clear.
In addition to managing of database connection, API via Session may provide
Printer and Status control of a current process, Z Script analysis or
execution.
