Let's walk through how we might build our text map separate_words(), discussed in Section 68, creates two vectors: a string vector of each word of the text, and a location vector that holds a line and column pair of values For each word element in the string vector, the equivalent element of the location vector provides the line and column information for that word The string vector, that is, provides the collection of key values for our text map The location vector provides the associated collection of values separate_words() returns these two vectors in a pair object that holds a pointer to each The argument to our build_word_map() function is this pair object The return value is the text location map or, rather, a pointer to it:

// typedefs to make declarations easier typedef pair< short,short > location; typedef vector< location > loc; typedef vector< string > text; typedef pair< text*,loc* > text_loc; extern map< string, loc* >* build_word_map( const text_loc *text_locations );

Our first prepatory steps are to allocate the empty map from the free store and to separate the string and location vectors from the pair argument passed in as the argument:

map<string,loc*> *word_map = new map< string, loc* >; vector<string> *text_words = text_locations->first; vector<location> *text_locs = text_locations->second;

Read and extract PDF text from C# / VB.NET applications - GemBox
Read or load a PDF file and extract its text content in C# and VB.NET application with GemBox.Document library.

Ease of provisioning and reprovisioning is a strong benefit for the management of both blade and virtual environments. Most vendors sell software to provide these functions at various levels. You need to know how their management software interfaces with your current management software, or if your current software has add-ons that will allow you to manage the blade and virtual environments much as you have been managing your server and rack environments.

Next, we need to iterate across the two vectors in parallel There are two cases to consider: 1 The word does not yet exist within the map In this case, we need to insert the key/value pair 2 The word has already been inserted In this case, we need to update the location vector of the entry with the additional line and column information Here is our implementation:

register int elem_cnt = text_words->size(); for ( int ix = 0; ix < elem_cnt; ++ix ) { string textword = ( *text_words )[ ix ]; // exclusion strategies: do not enter in map // if fewer than 3 character // or if present in the exclusion set if ( textwordsize() < 3 || exclusion_setcount( textword )) continue;

// determine whether the word is present // if count() returns 0, not present -- add it if ( ! word_map->count((*text_words)[ix] )) { loc *ploc = new vector<location>; ploc->push_back( (*text_locs)[ix] ); word_map->insert( value_type( (*text_words)[ix], ploc )); } else // update the location vector of the entry (*word_map)[(*text_words)[ix]]->push_back((*text_locs)[ix]); }

(*word_map)[(*text_words)[ix]]->push_back((*text_locs)[ix]);

is perhaps more easily understood if we decompose it into its individual components:

Does your management tool include a change-control capability that will track what versions and patch levels of which operating environment, application software, and so on you re using and where they are located

// get the word to update string word = (*text_words)[ix]; // get the location vector vector<location> *ploc = (*word_map)[ word ]; // get the line and column pair location loc = (*text_locs)[ix]; // insert the new location pair ploc->push_back(loc);

The remaining syntactic complexity is a result of to our manipulating pointers to vectors rather than the vectors themselves To directly apply the subscript operator, we cannot write

Instead, we must first dereference our pointer:

Finally, build_word_map() returns our built-in map:

return word_map;

If you are thinking of implementing one or two chassis with a total of 20 blades, you may not think configuration-control management of this environment is much of an issue. However, when you also consider that each of those blades could support several virtual environments (let s say five to be conservative), you now are managing 100 server environments. It doesn t take a great stretch of the imagination to see how quickly managing a growing virtual environment can get out of hand. Therefore, if you don t currently have change-control capabilities within your server management environment, you should consider acquiring them.

Here is how we might invoke it within our main() function:

int main() { // read in and separate the text vector<string,allocator> *text_file = retrieve_text(); text_loc *text_locations = separate_words( text_file); // process the words // // build up the word/location map and invite query map<string,loc*,less<string>,allocator> *text_map = build_word_map( text_locations ); // }

Finding and Retrieving a Map Element The subscript operator provides the simplest method of retrieving a value For example:

// map<string,int> word_count; int count = word_count[ "wrinkles" ];
