Add a new block to the tree
- Parameters
-
| block | to be stored and added to tree |
- Returns
- nothing or error; if error happens, no changes in the tree are made
- Note
- if block, which is specified in PARENT_HASH field of (
- Parameters
-
| block) | is not in our local storage, corresponding error is returned. It is suggested that after getting that error, the caller would ask another peer for the parent block and try to insert it; this operation is to be repeated until a successful insertion happens |

Adds block body to the storage
- Parameters
-
| block_number | that corresponds to the block which body we are adding |
| block_hash | that corresponds to the block which body we are adding |
| block_body | that we are adding |
- Returns
- result with success if block body was inserted. Error otherwise

|
overridevirtual |
Add an existent block to the tree
- Parameters
-
| block_hash | is hash of the added block in the tree |
| block_header | is header of that block |
- Returns
- nothing or error; if error happens, no changes in the tree are made
Implements kagome::blockchain::BlockTree.
Definition at line 526 of file block_tree_impl.cpp.
Get a deepest leaf of the tree
- Returns
- deepest leaf
- Note
- deepest leaf is also a result of "SelectBestChain": if we are the leader, we connect a block, which we constructed, to that deepest leaf

Get a chain of blocks from provided block to best block direction
- Parameters
-

| maximum | number of blocks to be retrieved |
- Returns
- chain or blocks or error
Implements kagome::blockchain::BlockTree.
Definition at line 756 of file block_tree_impl.cpp.
Get the most recent block of the best (longest) chain among those that contain a block with.
- Parameters
-
| target_hash | |
| target_hash | is a hash of a block that the chosen chain must contain |
| max_number | is the max block number that the resulting block (and the target one) may possess |

Definition at line 969 of file block_tree_impl.cpp.
Get a body (extrinsics) of the block (if present)
- Parameters
-
| block | - id of the block to get body for |
- Returns
- body, if the block exists in our storage, error in case it does not exist in our storage, or actual error happens
Implements kagome::blockchain::BlockTree.
Definition at line 742 of file block_tree_impl.cpp.
Get block header by provided block id
- Parameters
-
| block | id of the block header we are looking for |
- Returns
- result containing block header if it exists, error otherwise
Implements kagome::blockchain::BlockTree.
Definition at line 735 of file block_tree_impl.cpp.
Get a justification of the block (if present)
- Parameters
-
| block | - id of the block to get justification for |
- Returns
- body, if the block exists in our storage, error in case it does not exist in our storage, or actual error happens
Implements kagome::blockchain::BlockTree.
Definition at line 750 of file block_tree_impl.cpp.
Get a chain of blocks. Implies hasDirectChain(ancestor, descendant).
- Parameters
-
| ancestor | - block, which is closest to the genesis |
| descendant | - block, which is farthest from the genesis |
- Returns
- chain of blocks in ascending order or error
Implements kagome::blockchain::BlockTree.
Definition at line 847 of file block_tree_impl.cpp.
Get a chain of blocks before provided block including its
- Parameters
-
| block,to | which the chain is ended |
