Function OverrideLayerType

layertype.go:69–83

OverrideLayerType acts like RegisterLayerType, except that if the layer type has already been registered, it overrides the metadata with the passed-in metadata intead of panicing.

(num int, meta LayerTypeMetadata)

// has already been registered, it overrides the metadata with the passed-in
// metadata intead of panicing.
func OverrideLayerType(num int, meta LayerTypeMetadata) LayerType {
	if 0 <= num && num < maxLayerType {
		ltMeta[num] = layerTypeMetadata{
			inUse:             true,
			LayerTypeMetadata: meta,
		}
	} else {
		ltMetaMap[LayerType(num)] = layerTypeMetadata{
			inUse:             true,
			LayerTypeMetadata: meta,
		}
	}
	DecodersByLayerName[meta.Name] = meta.Decoder
	return LayerType(num)
}

// Decode decodes the given data using the decoder registered with the layer
// type.
