Detailed Description

An implementation of CommentDatabase backed by a Ghidra client.

Comment information about particular functions is obtained by querying a Ghidra client. All comments for a single function are queried at once, and results are cached in this object. The cache needs to be cleared between functions using the clear() method.

Member Function Documentation

addComment()

void CommentDatabaseGhidra::addComment ( uint4  tp, const Address &  fad, const Address &  ad, const string &  txt  )

virtual

For the Ghidra implementation of CommentDatabase, addComment() is currently only called by the warning routines which generates the warning and warningheader comment types. Neither of these types is intended to be a permanent comment in the database, so we only add the comment to the cache

Implements CommentDatabase.

addCommentNoDuplicate()

bool CommentDatabaseGhidra::addCommentNoDuplicate ( uint4  tp, const Address &  fad, const Address &  ad, const string &  txt  )

virtual

Add a new comment to the container, making sure there is no duplicate.

If there is already a comment at the same address with the same body, no new comment is added.

Parameters

tp	is a set of properties to associate with the new comment (may be zero)
fad	is the address of the function to which the comment belongs
ad	is the address to which the comment is attached
txt	is the body of the comment

Returns

true if a new Comment was created, false if there was a duplicate

Implements CommentDatabase.

beginComment()

CommentSet::const_iterator CommentDatabaseGhidra::beginComment ( const Address &  fad ) const

virtual

Get an iterator to the beginning of comments for a single function.

Parameters

fad	is the address of the function

Returns

the beginning iterator

Implements CommentDatabase.

clearType()

virtual void CommentDatabaseGhidra::clearType ( const Address &  fad, uint4  tp  )

inlinevirtual

Clear all comments matching (one of) the indicated types.

Clearing is restricted to comments belonging to a specific function and matching at least one of the given properties

Parameters

fad	is the address of the owning function
tp	is a set of one or more properties

Implements CommentDatabase.

deleteComment()

virtual void CommentDatabaseGhidra::deleteComment ( Comment *  com )

inlinevirtual

Remove the given Comment object from the container.

Parameters

com	is the given Comment

Implements CommentDatabase.

endComment()

CommentSet::const_iterator CommentDatabaseGhidra::endComment ( const Address &  fad ) const

virtual

Get an iterator to the ending of comments for a single function.

Parameters

fad	is the address of the function

Returns

the ending iterator

Implements CommentDatabase.

restoreXml()

virtual void CommentDatabaseGhidra::restoreXml ( const Element *  el, const AddrSpaceManager *  manage  )

inlinevirtual

Restore all comments from XML.

Parameters

el	is the root <commentdb> element
manage	is a manager for resolving address space references

Implements CommentDatabase.

saveXml()

virtual void CommentDatabaseGhidra::saveXml ( ostream &  s ) const

inlinevirtual

Save all comments in the container to an XML stream.

Writes a <commentdb> tag, with <comment> sub-tags for each Comment object.

Parameters

s	is the output stream

Implements CommentDatabase.
