Definition: layer.h:93
virtual SDF_API bool WriteToString(const SdfLayer &layer, std::string *str, const std::string &comment=std::string()) const
Writes the content in layer to the string str.
virtual SDF_API bool CanRead(const std::string &file) const =0
Returns true if file can be read by this format.
#define TF_DECLARE_WEAK_AND_REF_PTRS(type)
Define standard weak, ref, and vector pointer types.
Definition: declarePtrs.h:89
virtual SDF_API bool Read(SdfLayer *layer, const std::string &resolvedPath, bool metadataOnly) const =0
Reads scene description from the asset specified by resolvedPath into the layer layer.
#define TF_DECLARE_PUBLIC_TOKENS(...)
Macro to define public tokens.

std::map< std::string, std::string > FileFormatArguments
Type for specifying additional file format-specific arguments to the various API below.
Definition: fileFormat.h:113
virtual SDF_API SdfAbstractDataRefPtr InitData(const FileFormatArguments &args) const
This method allows the file format to bind to whatever data container is appropriate.
virtual SDF_API bool ReadFromString(SdfLayer *layer, const std::string &str) const
Reads data in the string str into the layer layer.
virtual SDF_API bool WriteToStream(const SdfSpecHandle &spec, std::ostream &out, size_t indent) const
Write the provided spec to out indented indent levels.
virtual SDF_API bool WriteToFile(const SdfLayer &layer, const std::string &filePath, const std::string &comment=std::string(), const FileFormatArguments &args=FileFormatArguments()) const
Writes the content in layer into the file at filePath.
Base class for file format implementations.
