Modifier and Type	Method and Description
`protected Date`	`getDate(Osmformat.Info info)` Take a Info protocol buffer containing a date and convert it into a java Date object
`protected String`	`getStringById(int id)` Get a string based on the index used.
`protected long`	`getTimestamp(Osmformat.Info info)`
`void`	`handleBlock(FileBlock message)` Called with the data in the block.
`protected abstract void`	`parse(Osmformat.HeaderBlock header)` Parse a header message.
`void`	`parse(Osmformat.PrimitiveBlock block)` Parse a Primitive block (containing a string table, other paramaters, and PrimitiveGroups
`protected abstract void`	`parseDense(Osmformat.DenseNodes nodes)` Parse a DenseNode protocol buffer and send the resulting nodes to a sink.
`double`	`parseLat(long degree)` Convert a latitude value stored in a protobuf into a double, compensating for granularity and latitude offset
`double`	`parseLon(long degree)` Convert a longitude value stored in a protobuf into a double, compensating for granularity and longitude offset
`protected abstract void`	`parseNodes(List<Osmformat.Node> nodes)` Parse a list of Node protocol buffers and send the resulting nodes to a sink.
`protected abstract void`	`parseRelations(List<Osmformat.Relation> rels)` Parse a list of Relation protocol buffers and send the resulting relations to a sink.
`protected abstract void`	`parseWays(List<Osmformat.Way> ways)` Parse a list of Way protocol buffers and send the resulting ways to a sink.
`boolean`	`skipBlock(FileBlockPosition block)` Does the reader understand this block? Does it want the data in it? A reference contains the metadata about a block and can saved --- or stored ---- for future random access.

```
  - getStringById
```
protected String getStringById(int id)
```
    Get a string based on the index used. Index 0 is reserved to use as a delimiter, therefore, index 1 corresponds to the first string in the table
    
    Parameters:
    
    id -
    
    Returns:
  - handleBlock
```
public void handleBlock(FileBlock message)
                 throws IOException
```
    Description copied from interface: BlockReaderAdapter
    
    Called with the data in the block.
    
    Specified by:
    
    handleBlock in interface BlockReaderAdapter
    
    Throws:
    
    IOException
  - skipBlock
```
public boolean skipBlock(FileBlockPosition block)
```
    Description copied from interface: BlockReaderAdapter
    
    Does the reader understand this block? Does it want the data in it? A reference contains the metadata about a block and can saved --- or stored ---- for future random access. However, during a strea read of the file, does the user want this block? handleBlock will be called on all blocks that are not skipped, in file order.
