AttrIterator

open class AttrIterator : AttrIteratorProtocol

A PangoAttrIterator is used to iterate through a PangoAttrList.

A new iterator is created with [methodPango.AttrList.get_iterator]. Once the iterator is created, it can be advanced through the style changes in the text using [methodPango.AttrIterator.next]. At each style change, the range of the current style segment and the attributes currently in effect can be queried.

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

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

    For type-safe access, use the generated, typed pointer attr_iterator_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 AttrIterator instance.

    Declaration

    Swift

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

    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 AttrIterator instance.

    Declaration

    Swift

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

    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 AttrIterator instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • 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 AttrIterator 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 AttrIterator instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements AttrIteratorProtocol PangoAttrIterator does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements AttrIteratorProtocol

    Parameters

    cPointer

    pointer to the underlying object
