A Pango::Coverage represents a map from ISO-10646 character point to Pango::CoverageLevel. 
It is often necessary in pango to determine if a particular font can represent a particular character, and also how well it can represent that character. Pango::Coverage holds this information. 
◆ Coverage() [1/2]
  
  | 
        
          | Pango::Coverage::Coverage | ( |  | ) |  |  | delete | 
 
 
◆ Coverage() [2/2]
  
  | 
        
          | Pango::Coverage::Coverage | ( | const Coverage& |  | ) |  |  | delete | 
 
 
◆ create() [1/2]
◆ create() [2/2]
Convert data generated from pango_coverage_to_bytes() back to a Pango::Coverage. 
- Parameters
- 
  
    | bytes | Binary data representing a Pango::Coverage. |  | n_bytes | The size of bytes in bytes. |  
 
- Returns
- A newly allocated Pango::Coverage, or nullptrif the data was invalid.
 
 
◆ get()
Determine whether a particular index is covered by coverage. 
- Parameters
- 
  
  
- Returns
- The coverage level of coverage for character index. 
 
 
◆ gobj() [1/2]
      
        
          | PangoCoverage* Pango::Coverage::gobj | ( |  | ) |  | 
      
 
Provides access to the underlying C instance. 
 
 
◆ gobj() [2/2]
      
        
          | const PangoCoverage* Pango::Coverage::gobj | ( |  | ) | const | 
      
 
Provides access to the underlying C instance. 
 
 
◆ gobj_copy()
      
        
          | PangoCoverage* Pango::Coverage::gobj_copy | ( |  | ) | const | 
      
 
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs. 
 
 
◆ max()
Set the coverage for each index in coverage to be the max (better) value of the current coverage for the index and the coverage for the corresponding index in other. 
- Parameters
- 
  
  
 
 
◆ operator delete()
  
  | 
        
          | void Pango::Coverage::operator delete | ( | void * | , |  
          |  |  | std::size_t |  |  
          |  | ) |  |  |  | protected | 
 
 
◆ operator=()
◆ reference()
      
        
          | void Pango::Coverage::reference | ( |  | ) | const | 
      
 
Increment the reference count for this object. 
You should never need to do this manually - use the object via a RefPtr instead. 
 
 
◆ set()
Modify a particular index within coverage. 
- Parameters
- 
  
    | index | The index to modify. |  | level | The new level for index. |  
 
 
 
◆ to_bytes()
Convert the coverage map into a flat binary format. 
- Returns
- An array of bytes representing the coverage map. 
 
 
◆ unreference()
      
        
          | void Pango::Coverage::unreference | ( |  | ) | const | 
      
 
Decrement the reference count for this object. 
You should never need to do this manually - use the object via a RefPtr instead. 
 
 
◆ wrap()
A Glib::wrap() method for this object. 
- Parameters
- 
  
    | object | The C instance. |  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |  
 
- Returns
- A C++ instance that wraps this C instance.
