CoverageProtocol

public protocol CoverageProtocol : ObjectProtocol

A PangoCoverage structure is a map from Unicode characters to [enumPango.CoverageLevel] values.

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. The PangoCoverage is a data structure that is used to represent that information. It is an opaque structure with no public fields.

The CoverageProtocol protocol exposes the methods and properties of an underlying PangoCoverage instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Coverage. Alternatively, use CoverageRef as a lighweight, unowned reference if you already have an instance you just want to use.

Coverage Class: CoverageProtocol extension (methods and fields)

  • copy() Extension method

    Copy an existing PangoCoverage.

    Declaration

    Swift

    @inlinable
func copy() -> Pango.CoverageRef!
    Show on GitHub
  • get(index:) Extension method

    Determine whether a particular index is covered by coverage.

    Declaration

    Swift

    @inlinable
func get(index: Int) -> PangoCoverageLevel
    Show on GitHub
  • max(other:) Extension method

    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.

    max is deprecated: This function does nothing

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func max<CoverageT>(other: CoverageT) where CoverageT : CoverageProtocol
    Show on GitHub
  • ref() Extension method

    Increase the reference count on the PangoCoverage by one.

    ref is deprecated: Use g_object_ref instead

    Declaration

    Swift

    @available(*, deprecated)
@discardableResult
@inlinable
func ref() -> Pango.CoverageRef!
    Show on GitHub
  • set(index:level:) Extension method

    Modify a particular index within coverage

    Declaration

    Swift

    @inlinable
func set(index: Int, level: PangoCoverageLevel)
    Show on GitHub
  • to(bytes:nBytes:) Extension method

    Convert a PangoCoverage structure into a flat binary format.

    to_bytes is deprecated: This returns %NULL

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func to(bytes: UnsafeMutablePointer<UnsafeMutablePointer<guchar>?>!, nBytes: UnsafeMutablePointer<gint>!)
    Show on GitHub
  • unref() Extension method

    Decrease the reference count on the PangoCoverage by one.

    If the result is zero, free the coverage and all associated memory.

    unref is deprecated: Use g_object_unref instead

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func unref()
