bool UsdUsdzFileFormat::_ReadDetached ( SdfLayer layer,
const std::string resolvedPath,
bool  metadataOnly 
) const
overrideprotectedvirtual
See Also
ReadDetached

Upon completion, layer must have an SdfAbstractData object set that is detached, i.e. SdfAbstractData::IsDetached returns false.

The default implementation calls _ReadAndCopyLayerDataToMemory to read the specified layer and copy its data into an SdfData object if it is not detached. If data is copied, a warning will be issued since this may be an expensive operation. If the above behavior is desired, subclasses can just call _ReadAndCopyLayerDataToMemory to do the same thing but without the warning.

Reimplemented from SdfFileFormat.

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.
