Detailed Description

Private implementation class for the MasterLoader.

This class is used internally by the MasterLoader and is not publicly visible. It is present to avoid polluting the public API with internal implementation details of the MasterLoader.

Definition at line 60 of file master_loader.cc.

Constructor & Destructor Documentation

◆ MasterLoaderImpl()

isc::dns::MasterLoader::MasterLoaderImpl::MasterLoaderImpl	(	const char *	master_file,
		const Name &	zone_origin,
		const RRClass &	zone_class,
		const MasterLoaderCallbacks &	callbacks,
		const AddRRCallback &	add_callback,
		MasterLoader::Options	options )

inline

Constructor.

Parameters

master_file	Path to the file to load.
zone_origin	The origin of zone to be expected inside the master file. Currently unused, but it is expected to be used for some validation.
zone_class	The class of zone to be expected inside the master file.
callbacks	The callbacks by which it should report problems. Usually, the callback carries a filename and line number of the input where the problem happens. There's a special case of empty filename and zero line in case the opening of the top-level master file fails.
add_callback	The callback which would be called with each loaded RR.
options	Options for the parsing, which is bitwise-or of the Options values or DEFAULT. If the MANY_ERRORS option is included, the parser tries to continue past errors. If it is not included, it stops at first encountered error.

Exceptions

std::bad_alloc when there's not enough memory.

◆ getPosition()

size_t isc::dns::MasterLoader::MasterLoaderImpl::getPosition ( ) const

inline

Return the line number being parsed in the pushed input sources.

See MasterLexer::getPosition().

◆ getSize()

size_t isc::dns::MasterLoader::MasterLoaderImpl::getSize ( ) const

inline

Return the total size of the input sources pushed so far.

See MasterLexer::getTotalSourceSize().

◆ loadIncremental()

Here is the call graph for this function:

◆ pushSource()

void isc::dns::MasterLoader::MasterLoaderImpl::pushSource	(	const std::string &	filename,
		const Name &	current_origin )

inline

Wrapper around MasterLexer::pushSource() (file version)

This method is used as a wrapper around the lexer's pushSource() to also save the current origin and the last seen name (to be restored upon popSource()). It also calls pushSource(). See doInclude() implementation for more details.

Parameters

filename	Path to the file to push as a new source.
current_origin	The current origin name to save.

Definition at line 116 of file master_loader.cc.

References isc_throw, and isc::dns::MasterLexer::pushSource().

Here is the call graph for this function:

◆ pushStreamSource()

void isc::dns::MasterLoader::MasterLoaderImpl::pushStreamSource ( std::istream & stream )

inline

Wrapper around MasterLexer::pushSource() (stream version)

Similar to pushSource(). This method need not save the current origin as it is not used with $INCLUDE processing.

Parameters

stream The input stream to use as a new source.
