public class HLogPrettyPrinter
extends WALPrettyPrinter

HLogPrettyPrinter prints the contents of a given HLog with a variety of options affecting formatting and extent of content. It targets two usage cases: pretty printing for ease of debugging directly by humans, and JSON output for consumption by monitoring and/or maintenance scripts. It can filter by row, region, or sequence id. It can also toggle output of values.

public HLogPrettyPrinter()

Deprecated.

Basic constructor that simply initializes values to reasonable defaults.

HLogPrettyPrinter

public HLogPrettyPrinter(boolean outputValues,
                 boolean outputJSON,
                 long sequence,
                 String region,
                 String row,
                 boolean persistentOutput,
                 PrintStream out)

Deprecated.

Fully specified constructor.

Parameters:

outputValues - when true, enables output of values along with other log information

outputJSON - when true, enables output in JSON format rather than a "pretty string"

sequence - when nonnegative, serves as a filter; only log entries with this sequence id will be printed

region - when not null, serves as a filter; only log entries from this region will be printed

row - when not null, serves as a filter; only log entries from this row will be printed

persistentOutput - keeps a single list running for multiple files. if enabled, the endPersistentOutput() method must be used!

out - Specifies an alternative to stdout for the destination of this PrettyPrinter's output.
