Constructor & Destructor Documentation

◆ ~SdfTextFileFormat()

virtual SDF_API ~SdfTextFileFormat ( )
protectedvirtual

Destructor.

◆ SdfTextFileFormat() [1/2]

SDF_API SdfTextFileFormat ( )
protected

Constructor.

◆ SdfTextFileFormat() [2/2]

SDF_API SdfTextFileFormat ( const TfToken formatId,
const TfToken versionString = TfToken(),
const TfToken target = TfToken() 
)
explicitprotected

Constructor.

This form of the constructor may be used by formats that use the .sdf text format as their internal representation. If a non-empty versionString and target are provided, they will be used as the file format version and target; otherwise the .sdf format version and target will be implicitly used.

Member Function Documentation

◆ _CanReadFromAsset()

SDF_API bool _CanReadFromAsset ( const std::string &  resolvedPath,
const std::shared_ptr< ArAsset > &  asset 
) const
protected

Return true if layer can be read from asset at resolvedPath.

◆ _ReadFromAsset()

SDF_API bool _ReadFromAsset ( SdfLayer layer,
const std::string &  resolvedPath,
const std::shared_ptr< ArAsset > &  asset,
bool  metadataOnly 
) const
protected

Read layer from asset at resolvedPath into layer.

◆ CanRead()

virtual SDF_API bool CanRead ( const std::string &  file) const
overridevirtual

Returns true if file can be read by this format.

Implements SdfFileFormat.

◆ Read()

virtual SDF_API bool Read ( SdfLayer layer,
const std::string &  resolvedPath,
bool  metadataOnly 
) const
overridevirtual

Reads scene description from the asset specified by resolvedPath into the layer layer.

metadataOnly is a flag that asks for only the layer metadata to be read in, which can be much faster if that is all that is required. Note that this is just a hint: some FileFormat readers may disregard this flag and still fully populate the layer contents.

Returns true if the asset is successfully read into layer, false otherwise.

Implements SdfFileFormat.

◆ ReadFromString()

virtual SDF_API bool ReadFromString ( SdfLayer layer,
const std::string &  str 
) const
overridevirtual

Reads data in the string str into the layer layer.

If the file is successfully read, this method returns true. Otherwise, false is returned and errors are posted.

Reimplemented from SdfFileFormat.

◆ WriteToFile()

virtual SDF_API bool WriteToFile ( const SdfLayer layer,
const std::string &  filePath,
const std::string &  comment = std::string(),
const FileFormatArguments args = FileFormatArguments() 
) const
overridevirtual

Writes the content in layer into the file at filePath.

If the content is successfully written, this method returns true. Otherwise, false is returned and errors are posted. The default implementation returns false.

Reimplemented from SdfFileFormat.

◆ WriteToStream()

virtual SDF_API bool WriteToStream ( const SdfSpecHandle &  spec,
std::ostream &  out,
size_t  indent 
) const
overridevirtual

Write the provided spec to out indented indent levels.

Reimplemented from SdfFileFormat.

◆ WriteToString()

virtual SDF_API bool WriteToString ( const SdfLayer layer,
std::string *  str,
const std::string &  comment = std::string() 
) const
overridevirtual

Writes the content in layer to the string str.

This function should write a textual representation of layer to the stream that can be read back in via ReadFromString.

Reimplemented from SdfFileFormat.
