Types ¶
type RTree ¶
type RTree struct { // // `count` is the number of items in the tree. // Count uint32 `protobuf:"varint,1,opt,name=count,proto3" json:"count,omitempty"` // // `refs[:count]` are external references to the items being indexed. // The values are generally determined by insertion order, but can be // any 64-bit integer. // // `refs[count:]` are internal references to positions in the `boxes` // list, and represent the start position of child bounding boxes for // a node. We can retrieve sibling boxes using pairwise references: // // boxes[refs[i]:refs[i+1]] // // The position of a reference in `refs` corresponds to the position // of its bounding box in `boxes`. The reference for the bounding box // at `boxes[i:i+4]` is `refs[i/4]`. // // The layout of `refs` might look like this, where the number of // levels depends on node size and the number of items: // +-----------------------------------------------------------+ // | level 3 (leaves) | level 2 | level 1 | root | // +-----------------------------------------------------------+ // ^ // refs[count] // Refs []int64 `protobuf:"varint,2,rep,packed,name=refs,proto3" json:"refs,omitempty"` // // `boxes` is a flat list of 2-D axis-aligned bounding boxes. // // `boxes[:count*4]` are the external item bounding boxes. // `boxes[count*4:]` are the internal node bounding boxes. // // The layout of `boxes` might look like this, where the number of // levels depends on node size and the number of items: // +-----------------------------------------------------------+ // | level 3 (leaves) | level 2 | level 1 | root | // +-----------------------------------------------------------+ // ^ // boxes[count*4] // // Bounding boxes are encoded as min point and max point: // // xmin, ymin, xmax, ymax // // The coordinate values are multiplied by `10^precision` and // stored as signed, 64-bit integers in order to take advantage // of varint encoding to reduce the size in bytes. This technique // is borrowed from the Geobuf protobuf format. // Boxes []int64 `protobuf:"zigzag64,3,rep,packed,name=boxes,proto3" json:"boxes,omitempty"` // // `precision` is used to convert 64-bit float coordinates // to/from signed integers. // Precision uint32 `protobuf:"varint,4,opt,name=precision,proto3" json:"precision,omitempty"` // contains filtered or unexported fields }
