  • Method Details

    • getMainMolecule

      public abstract Molecule getMainMolecule(int irec, Molecule mol)
      Gets the main molecule object in a record.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      Returns:
      the main molecule object or null if it does not exist

    • getKeys

      public abstract String[] getKeys(int irec, Molecule mol)
      Gets the keys in a record.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      Returns:
      the array of keys

    • getFields

      public abstract void getFields(int irec, Molecule mol, String[] keys, MProp[] values)
      Extracts properties.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      keys - array of field keys
      values - the output array, may contain null if a property is not found

    • setFields

      public abstract void setFields(int irec, Molecule mol, String[] keys, MProp[] values)
      Sets properties.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      keys - array of field keys
      values - array of values

    • isEditable

      public abstract boolean isEditable(int irec, Molecule mol, String key)
      Tests whether a field is editable or not.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      key - the field key
      Returns:
      true if setFields works for this key, false otherwise

    • setField

      public final void setField(int irec, Molecule mol, String key, MProp p)
      Sets a property.
      Parameters:
      irec - the record number
      mol - input molecule, may be null in case of an implementation for which the record number is enough
      key - the field key
      p - the property value

    • propToString

      protected String propToString(MProp p)
      Converts a property to a string. Utility method called by implementations.
      Parameters:
      p - the property
      Returns:
      the string value
