Instant JChem Developers guide

Instant JChem 3.0 -> 5.3.1

IJC is undergoing extensive development, largely as a result of the IJC server functionality. As a result, many parts of the API cannot be considered stable. This will remain the case until the IJC server developments are complete. If you are needing a stable environment to develop against we would recommend using the IJC 3.0.4 as the base until the IJC server developments are complete.

Despite this some areas of the APIs can be considered mostly stable, and if you are building functionality that sits on top of IJC then this is probably sufficient for your needs. This includes mainly: Stable DIF API packages and IJC Core API

• String ID fields (primary key of DFEntity) are allowed now. Originally just Integer was accepted as valid type.
• Method DFField.getDefaultValue) now returns a new type (instead of Object)

Instant JChem 2.4 -> 3.0

• Class DocumentAdapter moved to IM Commons module to package com.im.commons.util.

Instant JChem 2.3 -> 2.4

• A new module IM Commons for common utilities was created.
  • Display name: IM Commons
  • Code name: com.im.commons
  • Documentation: Javadoc API
  • You probably need to add dependency on this new module as a few core classes were moved from DIF to this module:
    • DFFeedback
    • CancelException
    • CaseInsensitive collections (List, Map, Set)
• Original DIF module was split. A new module DIF API was created and most of stable DIF APIs was moved to this new module. You need to add dependency on this module.
  New DIF API module:
  • Display name: DIF API
  • Code name: com.im.df.api
  • Documentation: Javadoc API
  Original DIF module:
  • Display name: DIF Core Implemenation (renamed from DIF)
  • Code name: com.im.df.api (unchanged)
  • Documentation: Javadoc API
  • This module's API now containts: SPI backdoor to DIF Core Impl classes, old classes which will be refactored in next versions, some other remaining utilities which will be probably also moved to DIF API module in next IJC version
• Packages and class level refactoring changes. Check Javadoc documentation for more info.
  • chem.api package moved to df.api
  • EnvUtils class moved
  • Temporary class LegacyConstants was created instead of using links directly to DIF Core Impl
  • A new BatchUpdaterclass supports data changes in batches (support for doing changes for more rows)
  • UndoConfig
• Some minor (mainly method level) changes. Check Javadoc documentation for more info.
  • DFEntityDataProvider.getRowCount() method signature
  • isCancelled() method moved from DFEnvironment to DFFeedback
  • a few ChemUtils methods signature changed
  • SelectionDescription now supports multiple intervals
  • DFEntityDataProvider.update methods changed
