Report only paths matching this regex.
Report only fields matching this regex.
Report only these times (n) or time ranges (ff..lf) for 'timeSamples' fields
Report times that are close to those requested within this relative tolerance. Default: 0.000125
Truncate arrays with more than this many elements. If -1, do not truncate arrays. Default: 0 for 'outline' output, 8 for 'pseudoLayer' output, and -1 for 'layer' output.
Truncate timeSamples with more than this many values. If -1, do not truncate timeSamples. Default: 0 for 'outline' output, 8 for 'pseudoLayer' output, and -1 for 'layer' output. Truncation performed after initial filtering by --time arguments.
Direct output to this file. Use the 'outputFormat' for finer control over the underlying format for output formats that are not uniquely determined by file extension.
Specify output format; 'summary' reports overall statistics, 'outline' is a flat text report of paths and fields, 'pseudoLayer' is similar to the usda file format but with truncated array values and timeSamples for human readability, and 'layer' is true layer output, with the format controlled by the 'out' and 'outputFormat' arguments. Default: outline
Supply this as the 'format' entry of SdfFileFormatArguments for 'layer' output to a file. Requires both 'layer' output and a specified output file.
Group 'outline' output by either path or field. Ignored for other output types. Default: path
Do not report field values.
