Member Function Documentation

virtual bool CanRead ( const string &  file) const
overridevirtual

Returns true if file can be read by this format.

Implements SdfFileFormat.

virtual SdfAbstractDataRefPtr 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 bool Read ( SdfLayer layer,
const 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 bool ReadFromString ( SdfLayer layer,
const 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 bool WriteToFile ( const SdfLayer layer,
const string &  filePath,
const string &  comment = 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 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.

virtual bool WriteToString ( const SdfLayer layer,
string *  str,
const string &  comment = 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.
