PixbufModulePattern

open class PixbufModulePattern : PixbufModulePatternProtocol

The signature prefix for a module.

The signature of a module is a set of prefixes. Prefixes are encoded as pairs of ordinary strings, where the second string, called the mask, if not NULL, must be of the same length as the first one and may contain ‘ ’, ‘!’, ‘x’, ‘z’, and ‘n’ to indicate bytes that must be matched, not matched, “don’t-care”-bytes, zeros and non-zeros, respectively.

Each prefix has an associated integer that describes the relevance of the prefix, with 0 meaning a mismatch and 100 a “perfect match”.

Starting with gdk-pixbuf 2.8, the first byte of the mask may be ‘’, indicating an unanchored pattern that matches not only at the beginning, but also in the middle. Versions prior to 2.8 will interpret the ‘’ like an ‘x’.

The signature of a module is stored as an array of GdkPixbufModulePatterns. The array is terminated by a pattern where the prefix is NULL.

GdkPixbufModulePattern *signature[] = {
  { "abcdx", " !x z", 100 },
  { "bla", NULL,  90 },
  { NULL, NULL, 0 }
};

In the example above, the signature matches e.g. “auud\0” with relevance 100, and “blau” with relevance 90.

The PixbufModulePattern type acts as an owner of an underlying GdkPixbufModulePattern instance. It provides the methods that can operate on this data type through PixbufModulePatternProtocol conformance. Use PixbufModulePattern as a strong reference or owner of a GdkPixbufModulePattern instance.

  • ptr
    Untyped pointer to the underlying `GdkPixbufModulePattern` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!
  • Designated initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the PixbufModulePattern instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 PixbufModulePattern instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 PixbufModulePattern instance.

    Declaration

    Swift

    @inlinable
    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 PixbufModulePattern instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Optional 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 PixbufModulePattern instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafePointer<GdkPixbufModulePattern>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the PixbufModulePattern instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafeMutablePointer<GdkPixbufModulePattern>?)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. GdkPixbufModulePattern does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the PixbufModulePattern instance.

    Declaration

    Swift

    @inlinable
    public init(retaining op: UnsafeMutablePointer<GdkPixbufModulePattern>)

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements PixbufModulePatternProtocol GdkPixbufModulePattern does not allow reference counting.

    Declaration

    Swift

    @inlinable
    public init<T>(_ other: T) where T : PixbufModulePatternProtocol

    Parameters

    other

    an instance of a related type that implements PixbufModulePatternProtocol

  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to PixbufModulePatternProtocol.

    @inlinable
    public init<T>(cPointer p: UnsafeMutablePointer<T>)

    Parameters

    cPointer
