trace.getOperationObjectsAsJava(operationID)

Overview

Retrieves all MES objects associated with a traceability operation identified by its user-provided userID.

Returns live Java AbstractMESObject instances so scripts can call object methods directly—for example, reading material properties on a response segment or inspecting lot references—without working through serialized Python dictionaries. Use this when you need full object behavior after recording or modifying an operation with recordOperation() or modifyOperation().

Available in MES 3.81.6 RC 3 and later.

Syntax

Copy Code

Python

system.mes.trace.getOperationObjectsAsJava(userID)

Parameters

Parameter	Type	Required	Description
userID	String	Required	User-defined ID supplied when the operation was recorded with recordOperation(). Must match exactly one operations response in the database.

Return Value

Type	Description
List (Java)	Live MES objects linked to the operation. Each element is an AbstractMESObject subclass. When the operation is found, the list always includes at least the OperationsResponse object, followed by response segments and their associated references.

Objects included

The list is built from the matching Operations Response, its Response Segment(s), and each segment's associated references. Duplicate UUIDs appear only once.

Object type	Description
OperationsResponse	The top-level operation response for the userID. Always included when the operation is found.
ResponseSegment	Response segment(s) attached to the operation.
MaterialLot	Lots consumed or created by material properties on the segment.
Material	Material definition references from material properties.
Equipment	Segment equipment, material storage equipment, and supplemental equipment references.
Person	Personnel assigned to the operation.

Associated references come from each segment's equipment, material, supplemental equipment, and personnel properties. Objects without resolvable MES object info are skipped.

Scope / Availability

Context	Available
Gateway scripts (TraceGatewayScript)	Yes
Client / Designer scripts (TraceClientScript)	Yes (via RPC to gateway)

Registered under system.mes.trace.

Excluded / Edge Cases

Operation not found — Raises IllegalArgumentException if no operations response exists for userID, or if userID is blank, null, or matches more than one operation.
No partial match — Lookup is by exact userID on the operations response; wildcards are not supported.
Disabled operations — Disabled operations can still be retrieved if the userID matches a stored operations response.
Property data vs. linked objects — Material quantities, timestamps, and other property fields live on the ResponseSegment complex properties (getMaterialProperties(), getPersonnelProperties(), and so on). The returned list contains the referenced MES objects (lots, equipment, persons), not separate objects for each property row.
Prefer Python dictionaries — Use getOperationObjectsAsPython() when you only need read-only, JSON-like data structures and do not need to call Java methods or save objects.

Example Usage

Minimal example

Retrieve objects for a previously recorded operation and log each type and name:

Copy Code

Python

userID = 'blend-op-001'

objects = system.mes.trace.getOperationObjectsAsJava(userID)

for obj in objects:
    typeName = obj.getMESObjectType().getName()
    system.util.getLogger('trace').info(
        '{}: {}'.format(typeName, obj.getName())
    )

Complex example

Record an operation, modify it, then read allocated quantity from the response segment material property:

Copy Code

Python

userID = 'pack-op-042'
equipmentPath = 'Enterprise/Site/Area/PackLine'
operationName = 'Packaging'

# Record the operation
system.mes.trace.recordOperation(
    name=operationName,
    equipmentPath=equipmentPath,
    userId=userID,
    materialOut=[
        system.mes.trace.configureMaterial(
            userId='output-material',
            name='Output',
            lotNo='LOT-1001',
            quantity=25.0,
            materialName='Finished Goods'
        )
    ]
)

# Modify quantity on the output material
system.mes.trace.modifyOperation(
    userId=userID,
    materialOut=[
        system.mes.trace.configureMaterial(
            userId='output-material',
            quantity=30.0
        )
    ]
)

# Load live Java objects and inspect the segment
objects = system.mes.trace.getOperationObjectsAsJava(userID)

segment = None
for obj in objects:
    if obj.getMESObjectType().getName() == 'ResponseSegment':
        segment = obj
        break

if segment:
    for matProp in segment.getMaterialProperties():
        propUserId = matProp.getUserID()
        quantity = matProp.getQuantity()
        lotUUID = matProp.getLotUUID() if matProp.hasLotRef() else None
        system.util.getLogger('trace').info(
            'Material {} qty={} lotUUID={}'.format(propUserId, quantity, lotUUID)
        )

    # Find the material lot object in the returned list
    for obj in objects:
        if obj.getMESObjectType().getName() == 'MaterialLot':
            system.util.getLogger('trace').info(
                'Lot {} UUID: {}'.format(obj.getName(), obj.getUUID())
            )
