Module oo 

Where a class definition is found. The run unit’s objects and classes, and running them, are rt::oo; compiling and checking a class is compile::oo.

Structs

Frame

The method an activation runs.

Instance

LoadedClass

MethodCall

A COBOL method’s activation: its code and loaded WORKING-STORAGE, the LINKAGE ordinal and address of each record of the object’s or the factory’s data, its arguments’ addresses, and the frame it runs in.

Objects

The run unit’s classes and objects, the references to them, and the JNI environment once a program uses JNIENVPTR.

Returned

How a method’s run ended, and when it ended normally, its RETURNING item’s name and value.

Running

Enums

Referent

What an object reference’s four bytes name.

Constants

JAVA_LANG_OBJECT

MAX_MEMORY

Run-unit memory past which creating objects and classes abends.

MAX_OBJECTS

Objects a run unit may create before it abends; they are never freed.

MAX_REFERENCES

References a run unit may make before it abends; each is kept, so that an expired one can say where it expired.

Traits

OoHost

What INVOKE and the JNI services ask of the executor beyond Values and the run unit: the method the activation runs, names and Java signatures, an argument’s bytes, and running a method.

Functions

bodies

bodies_mut

The statement lists bodies gives, those that are present, to change.

call_through_pointer

CALL through a FUNCTION-POINTER or PROCEDURE-POINTER: a JNI service from the function table, run here when it needs no JVM. Each argument is Value or Omitted, OMITTED as NULL. The reference services keep the JNI’s rules for local and global references (see LOCAL_FRAMES).

class_code

A class definition’s code, compiled at at, and the warnings and informational messages it compiled with.

compare_references

Two object references compare equal when they identify the same object (Language Reference SC27-8713-03, p. 282), so each is looked up; one compared with the figurative constant NULL is only tested for NULL. None when neither is an object reference; names names the two.

defined_class

The external name a class definition defines.

each_mut

[each], to change.

invoke

INVOKE: Arm(1) when no method matches and ON EXCEPTION is written, Arm(0) after a method ran when a phrase is written, Next when none is, or End after a STOP RUN. A CICS task refuses it (C147).

item_type

The Java type an item passes as, as a JNI signature spells it; a universal object reference passes as java.lang.Object.

jni_environment

The JNIENVPTR cell, pointing at the JNI environment, which points at the function table.

operand_type

The Java type of an INVOKE argument: an item, a one-character reference modification, LENGTH OF, or one of the literals IBM lists.

self_reference

SELF in method running, given its local reference the first time the method reads it.

Type Aliases

ClassCode

A COBOL class, compiled.

MethodCode

Part

FACTORY or OBJECT WORKING-STORAGE, laid out as a program’s, and where each record starts in it.
