gudusoft.gsqlparser.ir.builder.oracle.OracleExternalDepClassifier

public final class OracleExternalDepClassifier
extends Object

Classifies Oracle built-in functions, system packages, and other external dependencies that should NOT create virtual nodes in the call graph.

Instead of creating virtual nodes for these well-known Oracle constructs, they are marked as external dependencies (ExternalCallEdge), keeping the call graph focused on user-defined code entities.

Classification types:

• BUILTIN_FUNCTION — scalar built-in functions (NVL, TO_CHAR, etc.)
• AGGREGATE_FUNCTION — aggregate functions (SUM, COUNT, etc.)
• CONVERSION_FUNCTION — type conversion functions (TO_NUMBER, CAST, etc.)
• SYSTEM_PACKAGE — DBMS_*, UTL_*, SYS.* package calls
• SYSTEM_FUNCTION — system utility functions (RAISE_APPLICATION_ERROR, etc.)

Method Summary

Modifier and Type	Method and Description
static String	classify(String name) Classifies the external dependency type.
static boolean	isExternal(String name) Returns true if the given call name is a known Oracle external dependency (built-in function, system package call, etc.).
static boolean	isSecuritySensitive(String name) Returns true if the name is security-sensitive (audit-worthy).

Method Detail

isExternal

public static boolean isExternal(String name)

Returns true if the given call name is a known Oracle external dependency (built-in function, system package call, etc.).

For qualified names like "DBMS_OUTPUT.PUT_LINE", checks the package prefix. For unqualified names like "NVL", checks the built-in function set.

classify

public static String classify(String name)

Classifies the external dependency type.

Returns:

classification string (e.g., "BUILTIN_FUNCTION", "SYSTEM_PACKAGE")

isSecuritySensitive

public static boolean isSecuritySensitive(String name)

Returns true if the name is security-sensitive (audit-worthy). These are typically Oracle packages that provide file I/O, network access, or OS command execution capabilities.
