- com.luciad.format.dgn.server.TLcdDGNMicroStationModelDecoder

All Implemented Interfaces:: ILcdDGNModelDecoder, ILcdModelDecoder

Deprecated.

Use TLcdDGNModelDecoder instead, which also supports DGN V8 files.

@Deprecated
public class TLcdDGNMicroStationModelDecoder
extends Object
implements ILcdDGNModelDecoder

This model decoder decodes files in the DGN v7, DGN v8, and DWG formats. For retrieving the data, it uses Bentley's DGN API. It can therefore only be executed inside Bentley MicroStation, using the jmdl virtual machine, Bentley's extension of java.

Input files

File	Required	Entry point	Description
*.dgn	x	x	Design file (v7 or v8) containing vector data
*.dwg	x	x	Drawing file containing vector data

Since a DGN file itself doesn't specify a model reference, the corresponding model reference is retrieved with the help of the modelReferenceDecoder or as the defaultModelReference of this decoder. By default, the model reference decoder and the default model reference are unset (i.e. null).

Supported file transfer protocols

This model decoder only decodes files that can be accessed from the running copy of Bentley MicroStation.

Model structure

This model decoder creates a model per DGN file.
All models returned by this model decoder implement ILcd2DBoundsIndexedModel.

Model descriptor

All models returned by this model decoder have a TLcdDGNModelDescriptor. Among other information, the descriptor contains the DGN symbology.
The type name of the model descriptor is the display name of this decoder.

Model elements

Decoded models contain elements that all implement ILcdDGNShape.

The following DGN elements are currently supported:

DGN element type	DGN element name	Decoded object
1	LIBRARY_CELL
2	CELL	`TLcdDGNCell`
3	LINE	`TLcdDGNLine2D`
4	LINE_STRING	`TLcdDGNLineString2D`
5	GROUP_DATA
6	SHAPE	`TLcdDGNShape2D`
7	TEXT_NODE	`TLcdDGNText2D`
9	DESIGN_SETTINGS
10	LEVEL_SYMBOLOGY
11	CURVE	`TLcdDGNCurve2D`
12	COMPLEX_CHAIN	`TLcdDGNComplexChain`
14	COMPLEX_SHAPE	`TLcdDGNComplexShape`
15	ELLIPSE	`TLcdDGNEllipse2D`
16	ARC	`TLcdDGNArc2D`
17	TEXT	`TLcdDGNText2D`
18	3D_SURFACE	`TLcdDGN3DSurface`
19	SOLID	`TLcdDGNSolid`
34	SHARED_CELL_DEFINITION
35	SHARED_CELL_INSTANCE	`TLcdDGNCell`
36	CELL_MULTI_LINE	`TLcdDGNCell`
37	TAG_DATA

The following DGN elements that are not supported (basically splines, 3D surfaces, and rasters):

DGN element type	DGN element name
8	DIGITIZER_SETUP
13	CONIC
20	SUBFIGURE
21	B_SPLINE_CURVE
22	POINT_STRING
23	CONE
24	B_SPLINE_SURFACE

28	B_SPLINE
33	DIMENSION
66	APPLICATION
87	RASTER_HEADER

Useful settings

By default, all element levels are decoded. You can restrict the decoding to the levels you are interested in, using the following methods:
If you have restricted the levels to be decoded, you can still specify additional levels based on their names, using the following methods:
By default, all element classes are decoded. You can restrict the decoding to the classes you are interested in, using the following methods:
By default, no MSLINK attributes are decoded. You can control the decoding of MSLINK attributes based on the database types you are interested in, using the following methods:
In addition, you will need to specify the entity numbers you are interested in, as described in the following paragraph.
By default, no database attributes (either MSLINK or DMRS) are decoded. You can control the decoding of database attributes based on the database entity numbers you are interested in, using the following methods:
By default, no tag attributes are decoded. You can control the decoding of tag attributes based on the tag set names, using the following methods:
All decoded element attributes can have a String containing a URL assigned to them, for the convenience of the application that uses the decoder:
- setDatabaseURL(String)

Sample code


 ILcdModelDecoder decoder =
   new TLcdDGNMicroStationModelDecoder(new TLcdEPSGModelReferenceDecoder(),
                                       new TLcdGeodeticReference(new TLcdGeodeticDatum()));

 ILcdModel model = decoder.decode("vectordata.dgn");

Performance tips

By default, attributes are not decoded, potentially saving some memory and some processing time.
By default, decoded coordinates are stored as doubles. You can reduce the memory usage of the decoded models by storing coordinates in arrays of floats, using the following methods:
- setUseFloat(boolean)
- isUseFloat()

Thread safety

The decoding of models is not thread-safe.
The decoded models are thread-safe for read access.

Supported versions and specifications

DGN v7 and v8
DWG

Known limitations

This decoder can only be executed inside Bentley MicroStation, using the jmdl virtual machine.
The current implementation does not support splines, 3D surfaces, and rasters.

Requirements

The current implementation requires JMDL 1.3.

    Description copied from interface: ILcdDGNModelDecoder
    
    Sets the set of DGN database attributes that is decoded. Only DGN database attributes with the specified entity numbers will now be included in the models when decoding DGN files.
    
    Specified by:
    
    setAttributeEntitySelection in interface ILcdDGNModelDecoder
    
    Parameters:
    
    aEntities - a list of entity numbers of database attributes (user or non-user).
  - addAttributeEntity
```
public void addAttributeEntity(int aEntity)
```
    Deprecated.
    
    Description copied from interface: ILcdDGNModelDecoder
    
    Adds an attribute entity number to the set of numbers that is decoded. Only attributes that have entity numbers in this set are decoded.
    Note that, for decoding user attributes, the user attribute types to be decoded have to be specified as well, using the addUserAttributeType method.
    Also note that the fill color, which is also stored as an element attribute, is an exception: it is always decoded as part of the display info.
    
    Specified by:
    
    addAttributeEntity in interface ILcdDGNModelDecoder
    
    Parameters:
    
    aEntity - an entity number of an database attribute (user or non-user).

    Sets the set of DGN tag attributes that is decoded. Only the specified tag sets and their attributes will now be included in the models when decoding DGN files.
    
    Specified by:
    
    setTagSetSelection in interface ILcdDGNModelDecoder
    
    Parameters:

    Specified by:
    
    addTagSet in interface ILcdDGNModelDecoder
    
    Parameters:
    
    aTagSetName - a tag set name.
  - getDisplayName
```
public String getDisplayName()
```
    Deprecated.
    
    Description copied from interface: ILcdModelDecoder
    
    Returns a short, displayable name for the format that is decoded by this ILcdModelDecoder.
    
    Specified by:
    
    getDisplayName in interface ILcdModelDecoder
    
    Returns:
    
    the displayable name of this ILcdModelDecoder.
  - canDecodeSource
```
public boolean canDecodeSource(String aSourceName)
```
    Deprecated.
    
    Description copied from interface: ILcdModelDecoder
    
    Checks whether this model decoder can decode the specified data source. It is acceptable for this method to return true for a source name while decode throws an exception for that same source name.
    For performance reasons, we strongly recommend that this will only be a simple test. For example: check the file extension of a file, but not that the file exists or contains expected content.
    
    Specified by:
    
    canDecodeSource in interface ILcdModelDecoder
    
    Parameters:
    
    aSourceName - the data source to be verified; typically a file name or a URL.
    
    Returns:
    
    true if this decoder can likely decode the data specified by the source name, false otherwise.

  - decode
```
public ILcdModel decode(String aSourceName)
                 throws IOException
```
    Deprecated.
    
    Description copied from interface: ILcdModelDecoder
    
    Creates a new model from the given data source.
    Specified by:
    
    decode in interface ILcdModelDecoder
    
    Parameters:
    
    aSourceName - the data source to be decoded; typically a file name or a URL.
    
    Returns:
    
    A model containing the decoded data. While null is allowed, implementors are advised to throw an error instead.
    
    Throws:
    IOException - for any exceptions caused by IO problems or invalid data. Since decoding invalid data almost always results in RunTimeExceptions (NullPointerException, IndexOutOfBoundsException, IllegalArgumentException, ...) on unexpected places, implementations are advised to catch RuntimeExceptions in their decode() method, and wrap them into an IOException, as illustrated in the code snippet below.
    public ILcdModel decode( String aSourceName ) throws IOException { try (InputStream input = fInputStreamFactory.createInputStream(aSourceName)) { // Perform decoding ... } catch (RuntimeException e) { throw new IOException(e); } }
    InterruptedIOException - When the thread on which this method is called is interrupted: it is recommended to stop the decoding and throw an InterruptedIOException. This same exception can also be used if the decoder shows UI to the user, and the user cancels the decoding through the UI.
