SVN::Dump::Reader - A Subversion dump reader
SYNOPSIS
# !!! You should use SVN::Dump, not SVN::Dump::Reader !!!
use SVN::Dump::Reader;
my $reader = SVN::Dump::Reader( $fh );
my $record = $reader->read_record();
DESCRIPTION
The "SVN::Dump::Reader" class implements a reader object for Subversion dumps.
METHODS
The following methods are available:
new( $fh )
Create a new "SVN::Dump::Reader" attached to the $fh filehandle.
read_record( )
Read and return a new SVN::Dump::Record object from the dump filehandle.
read_header_block( )
Read and return a new SVN::Dump::Headers object from the dump filehandle.
read_property_block( )
Read and return a new SVN::Dump::Property object from the dump filehandle.
read_text_block( )
Read and return a new SVN::Dump::Text object from the dump filehandle.
The "read_..." methods will die horribly if asked to read inconsistent data from a stream.

SVN::Dump::Record - A SVN dump record
SYNOPSIS
# SVN::Dump::Record objects are returns by the next_record()
# method of SVN::Dump
DESCRIPTION
An "SVN::Dump::Record" object represents a Subversion dump record.
METHODS
"SVN::Dump" provides the following gourps of methods:
Record methods
new()
Create a new empty "SVN::Dump::Record" object.
type()
Return the record type, as guessed from its headers.
The method dies if the record type cannot be determined.
set_header( $h, $v )
Set the header $h to the value $v.
get_header( $h )
Get the value of header $h.
set_property( $p, $v )
Set the property $p to the value $v.
get_property( $p )
Get the value of property $p.
delete_property( @k )
Delete the
set_text( $t )
Set the value of the text block.
get_text()
Get the value of the text block.
Inner blocks manipulation
A "SVN::Dump::Record" is composed of several inner blocks of various kinds: "SVN::Dump::Headers", "SVN::Dump::Property" and
"SVN::Dump::Text".
The following methods provide access to these blocks:
set_headers_block( $headers )
get_headers_block()
Get or set the "SVN::Dump::Headers" object that represents the record headers.
set_property_block( $property )
get_property_block()
Get or set the "SVN::Dump::Property" object that represents the record property block.
delete_property( @keys )
Delete the given properties. Behave like the builtin "delete()".
set_text_block( $text )
get_text_block()
Get or set the "SVN::Dump::Text" object that represents the record text block.
set_included_record( $record )
get_included_record()
Some special record are actually output recursiveley by svnadmin dump. The "record in the record" is stored within the parent record,
so they are parsed as a single record with an included record.
"get_record()" / "set_record()" give access to the included record.
According to the Subversion sources (subversion/libsvn_repos/dump.c), this is a "delete original, then add-with-history" node. The dump
looks like this:
Node-path: tags/mytag/myfile
Node-kind: file
Node-action: delete
Node-path: tags/mytag/myfile
Node-kind: file
Node-action: add
Node-copyfrom-rev: 23
Node-copyfrom-path: trunk/myfile
Note that there is a single blank line after the first header block, and four after the included one.
update_headers()
Update the various "...-length" headers. Used internally.
You must call this method if you update the inner property or text blocks directly, or the results of "as_string()" will be
inconsistent.
Information methods
has_prop()
Return a boolean value indicating if the record has a property block.
has_text()
Return a boolean value indicating if the record has a text block.
has_prop_only()
Return a boolean value indicating if the record has only a property block (and no text block).
has_prop_or_text()
Return a boolean value indicating if the record has a property block or a text block.
property_length()
Return the length of the property block.
text_length()
Return the length of the text block.
Output method
as_string()
Return a string representation of the record.
Warning: dumping a record currenly gives back the information that was read from the original dump. Which means that if you modified
the property or text block of a record, the headers will be inconstent.
ENCAPSULATION
When using "SVN::Dump" to manipulate a SVN dump, one should not directly access the "SVN::Dump::Headers", "SVN::Dump::Property" and
"SVN::Dump::Text" components of a "SVN::Dump::Record" object, but use the appropriate "set_...()" and "get_...()" methods of the record
object.
These methods compute the appropriate modifications of the header values, so that the "as_string()" method outputs the correct information
after any modification of the record.
