Method Summary

Modifier and Type	Method	Description
protected java.util.Date	getDate(Osmformat.Info info)	Take a Info protocol buffer containing a date and convert it into a java Date object
protected java.lang.String	getStringById(int id)	Get a string based on the index used.
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(java.util.List<Osmformat.Node> nodes)	Parse a list of Node protocol buffers and send the resulting nodes to a sink.
protected abstract void	parseRelations(java.util.List<Osmformat.Relation> rels)	Parse a list of Relation protocol buffers and send the resulting relations to a sink.
protected abstract void	parseWays(java.util.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.

Method Detail

getDate

protected java.util.Date getDate(Osmformat.Info info)

Take a Info protocol buffer containing a date and convert it into a java Date object

getStringById

protected java.lang.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)

Description copied from interface: BlockReaderAdapter

Called with the data in the block.

Specified by:

handleBlock in interface BlockReaderAdapter

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.

Specified by:

skipBlock in interface BlockReaderAdapter

parseLat

public double parseLat(long degree)

Convert a latitude value stored in a protobuf into a double, compensating for granularity and latitude offset

parseLon

public double parseLon(long degree)

Convert a longitude value stored in a protobuf into a double, compensating for granularity and longitude offset

parse

public void parse(Osmformat.PrimitiveBlock block)

Parse a Primitive block (containing a string table, other paramaters, and PrimitiveGroups

parseRelations

protected abstract void parseRelations(java.util.List<Osmformat.Relation> rels)

Parse a list of Relation protocol buffers and send the resulting relations to a sink.

parseDense

protected abstract void parseDense(Osmformat.DenseNodes nodes)

Parse a DenseNode protocol buffer and send the resulting nodes to a sink.

parseNodes

protected abstract void parseNodes(java.util.List<Osmformat.Node> nodes)

Parse a list of Node protocol buffers and send the resulting nodes to a sink.

parseWays

protected abstract void parseWays(java.util.List<Osmformat.Way> ways)

Parse a list of Way protocol buffers and send the resulting ways to a sink.

parse

protected abstract void parse(Osmformat.HeaderBlock header)

Parse a header message.
