Member Function Documentation

virtual USD_API bool UsdUsdzFileFormat::CanRead ( const std::string & file ) const

overridevirtual

Returns true if file can be read by this format.

Implements SdfFileFormat.

virtual USD_API std::string UsdUsdzFileFormat::GetPackageRootLayerPath ( const std::string & resolvedPath ) const

overridevirtual

Returns the path of the "root" layer contained in the package layer at resolvedPath produced by this file format. If this file format is not a package, returns the empty string.

The package root layer is the layer in the package layer that is used when that package is opened via SdfLayer.

Reimplemented from SdfFileFormat.

virtual USD_API SdfAbstractDataRefPtr UsdUsdzFileFormat::InitData ( const FileFormatArguments & args ) const

overridevirtual

This method allows the file format to bind to whatever data container is appropriate.

Returns a shared pointer to an SdfAbstractData implementation.

Reimplemented from SdfFileFormat.

virtual USD_API bool UsdUsdzFileFormat::IsPackage ( ) const

overridevirtual

Returns true if this file format is a package containing other assets.

Reimplemented from SdfFileFormat.

virtual USD_API bool UsdUsdzFileFormat::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 USD_API bool UsdUsdzFileFormat::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 USD_API bool UsdUsdzFileFormat::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.

virtual USD_API bool UsdUsdzFileFormat::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 USD_API bool UsdUsdzFileFormat::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.
