Interface ILcdDWGModelDecoder

All Superinterfaces:
ILcdModelDecoder
All Known Implementing Classes:
TLcdDWGModelDecoder, TLcdDWGModelListDecoder
public interface ILcdDWGModelDecoder extends ILcdModelDecoder
This interface provides common methods for decoders of the DWG file format.

Input files Link icon

File Required Entry point Description
*.dwg x x Drawing file containing vector data

Supported file transfer protocols Link icon

  • The supported file transfer protocols are specified by the implementations of this interface.

Model structure Link icon

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

Model descriptor Link icon

  • All models returned by this model decoder have a TLcdDWGModelDescriptor. Among other information, the descriptor contains the list of DWG layers and line styles.
  • The type name of the model descriptor is the display name of this decoder.

Model reference Link icon

  • Since a DWG file itself doesn't specify a model reference, the corresponding model reference is retrieved with the help of the modelReferenceDecoder, if it is set.
  • Alternatively, the decoder sets the defaultModelReference.

Model elements Link icon

  • Decoded models contain elements that all implement ILcdDWGShape.
  • The supported elements are specified by the implementations of this interface.

Useful settings Link icon

Performance tips Link icon

  • Invisible or frozen objects or layers are not decoded by default, potentially saving some memory and some processing time.

Thread safety Link icon

  • The decoding of models is not thread-safe, unless specified otherwise by the implementation of this interface.
  • The decoded models are thread-safe for read access.

Serialization Link icon

  • The decoded models and their contents implement Serializable and can be serialized.
  • Only de-serialization from data from the same release version is supported.

Supported versions and specifications Link icon

  • The supported versions are specified by the implementations of this interface.

  • Method Details Link icon

    • setModelReferenceDecoder Link icon

      void setModelReferenceDecoder(ILcdModelReferenceDecoder aModelReferenceDecoder)
      Sets the model reference decoder that will be used for creating model references for decoded models. The default is null.

    • getModelReferenceDecoder Link icon

      ILcdModelReferenceDecoder getModelReferenceDecoder()
      Returns the model reference decoder that is for creating model references for decoded models.

    • setDefaultModelReference Link icon

      void setDefaultModelReference(ILcdModelReference aDefaultModelReference)
      Sets the default model reference for decoded models, in case the model reference decoder doesn't provide one. The default is null.

    • getDefaultModelReference Link icon

      ILcdModelReference getDefaultModelReference()
      Returns the default model reference for decoded models.

    • setDecodeInvisibleObjects Link icon

      void setDecodeInvisibleObjects(boolean aDecodeInvisibleObjects)
      Specifies whether DWG objects that are marked as invisible should be decoded. The default is false.

    • isDecodeInvisibleObjects Link icon

      boolean isDecodeInvisibleObjects()
      Returns whether DWG objects that are marked as invisible are decoded.

    • setDecodeInvisibleLayers Link icon

      void setDecodeInvisibleLayers(boolean aDecodeInvisibleLayers)
      Specifies whether DWG layers that are marked as invisible should be decoded. The default is false.

    • isDecodeInvisibleLayers Link icon

      boolean isDecodeInvisibleLayers()
      Returns whether DWG layers that are marked as invisible are decoded.

    • setDecodeFrozenLayers Link icon

      void setDecodeFrozenLayers(boolean aDecodeFrozenLayers)
      Specifies whether DWG layers that are marked as frozen should be decoded. The default is false.

    • isDecodeFrozenLayers Link icon

      boolean isDecodeFrozenLayers()
      Returns whether DWG layers that are marked as frozen are decoded.

    • resetExtendedEntityTypeSelection Link icon

      void resetExtendedEntityTypeSelection()
      Resets the set of DWG extended entity types that is decoded. All extended entity data types will now be included in the models when decoding DWG files.
      See Also:

    • clearExtendedEntityTypeSelection Link icon

      void clearExtendedEntityTypeSelection()
      Clears the set of DWG extended entity types that is decoded. None of the extended entity data types will now be included in the models when decoding DWG files.
      See Also:

    • setExtendedEntityTypeSelection Link icon

      void setExtendedEntityTypeSelection(int[] aTypes)
      Sets the set of DWG extended entity types that is decoded. Only extended entity data with the specified types will now be included in the models when decoding DWG files.
      Parameters:
      aTypes - a list of extended entity types.
      See Also:

    • addExtendedEntityType Link icon

      void addExtendedEntityType(int aType)
      Adds a DWG extended entity type to the set of types that is decoded.
      Parameters:
      aType - an extended entity type.
      See Also:

    • resetExtendedEntityStringSelection Link icon

      void resetExtendedEntityStringSelection()
      Resets the set of DWG extended entity strings that is decoded. All DWG extended entity strings will now be included in the models when decoding DWG files.
      See Also:

    • clearExtendedEntityStringSelection Link icon

      void clearExtendedEntityStringSelection()
      Clears the set of DWG extended entity strings that is decoded. None of the DWG extended entity strings will now be included in the models when decoding DWG files.
      See Also:

    • setExtendedEntityStringSelection Link icon

      void setExtendedEntityStringSelection(String[] aStringPrefixes)
      Sets the set of DWG extended entity strings that is decoded. Only DWG extended entity strings with the specified prefixes will now be included in the models when decoding DWG files.
      Parameters:
      aStringPrefixes - a list of string prefixes.

    • addExtendedEntityString Link icon

      void addExtendedEntityString(String aStringPrefix)
      Adds a string prefix to the set of prefixes that determine which extended entity strings are decoded.
      Parameters:
      aStringPrefix - a list of string prefixes.
