Coverage

open class Coverage : GLibObject.Object, CoverageProtocol

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 Coverage type acts as a reference-counted owner of an underlying PangoCoverage instance. It provides the methods that can operate on this data type through CoverageProtocol conformance. Use Coverage as a strong reference or owner of a PangoCoverage instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Coverage instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<PangoCoverage>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Coverage instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<PangoCoverage>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Coverage instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Coverage instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object
