## Detailed Description

A Pango::Coverage represents a map from ISO-10646 character point to Pango::Coverage::Level.

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.

Level Pango::Coverage::get | ( | int | index | ) | const

Determine whether a particular index is covered by coverage.

Parameters

  index | The index to check.

Returns
  The coverage level of coverage for character index.

PangoCoverage* Pango::Coverage::gobj | ( |  | ) |

Provides access to the underlying C instance.

const PangoCoverage* Pango::Coverage::gobj | ( |  | ) | const

Provides access to the underlying C instance.

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.

void Pango::Coverage::operator delete | ( | void * | ,

| ) |  |
| protected

Coverage& Pango::Coverage::operator= | ( | const Coverage& |  | ) |
| delete

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.

void Pango::Coverage::set | ( | int | index,
|  | Level | level
| ) |  |

Modify a particular index within coverage.

Parameters

  index | The index to modify.
  level | The new level for index.

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.

## Friends And Related Function Documentation

Glib::RefPtr< Pango::Coverage > wrap | ( | PangoCoverage * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

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.
