Constructor & Destructor Documentation

virtual SDF_API SdfTextFileFormat::~SdfTextFileFormat ( )

protectedvirtual

Destructor.

SDF_API SdfTextFileFormat::SdfTextFileFormat ( )

protected

Constructor.

SDF_API SdfTextFileFormat::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

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

protected

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

SDF_API bool SdfTextFileFormat::_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.

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

overridevirtual

Returns true if file can be read by this format.

Implements SdfFileFormat.

virtual SDF_API bool SdfTextFileFormat::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.

virtual SDF_API bool SdfTextFileFormat::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.

virtual SDF_API bool SdfTextFileFormat::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.

This member function makes no distinction between a "Save" operation that updates the backing store for the layer itself and an "Export" operation that writes the layer data to a distinct asset. For file formats that retain all data in memory this is typically fine. But for file formats that handle data requests by reading from the backing store, this distinction can be important. In that case, additionally override the member function SaveToFile() to take different action.

Reimplemented from SdfFileFormat.

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

overridevirtual

Write the provided spec to out indented indent levels.

Reimplemented from SdfFileFormat.

virtual SDF_API bool SdfTextFileFormat::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.
