# Pango::Coverage Class Reference

List of all members.

## Detailed Description

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.

## Public Member Functions
CoverageLevel | get (int index) const
| Determine whether a particular index is covered by coverage.
const PangoCoverage* | gobj () const
| Provides access to the underlying C instance.
PangoCoverage* | gobj ()
| Provides access to the underlying C instance.
PangoCoverage* | 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 | max (const Glib::RefPtr<Coverage>& other) const
| 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 .
void | reference () const
void | set (int index, CoverageLevel level)
| Modify a particular index within coverage.
Glib::ArrayHandle< unsigned char > | to_bytes () const
| Convert the coverage map into a flat binary format.
void | unreference () const

## Member Function Documentation

static Glib::RefPtr<Coverage> Pango::Coverage::create | ( | const guchar* | bytes,
|  | int | n_bytes
| ) | `[static]`

  | Convert data generated from pango_converage_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 `0` if the data was invalid.

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

  | Determine whether a particular index is covered by coverage. Parameters:
  | index | The index to check.

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

| Provides access to the underlying C instance.

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

| 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::max | ( | const Glib::RefPtr<Coverage>& | other | ) | const

  | 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:
  | other | Another Pango::Coverage.

void Pango::Coverage::operator delete | ( | void* | ,
|  | size_t |
| ) | `[protected]`

void Pango::Coverage::reference | ( |  | ) | const

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

  | Modify a particular index within coverage. Parameters:
  | index | The index to modify.
  | level | The new level for index .

Glib::ArrayHandle<unsigned char> Pango::Coverage::to_bytes | ( |  | ) | const

| Convert the coverage map into a flat binary format. Returns: An array of bytes representing the coverage map.

void Pango::Coverage::unreference | ( |  | ) | const

## Friends And Related Function Documentation

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

  | 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.
