class: Coverage

[18:7] extends: object

A PangoCoverage structure is a map from Unicode characters to [enum@Pango.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.

Methods

• Coverage ()

  Create a new PangoCoverage

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• copy ()

  Copy an existing PangoCoverage.

• get (int index_)

  Determine whether a particular index is covered by @coverage.

  • @p index_ is the index to check.

• max (object other)

  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.

  • @p other is another PangoCoverage.
  • @r None.

• ref ()

  Increase the reference count on the PangoCoverage by one.

• set (int index_, string level)

  Modify a particular index within @coverage

  • @p index_ is the index to modify.
  • @p level is the new level for @index_.
  • @r None.

• unref ()

  Decrease the reference count on the PangoCoverage by one. If the result is zero, free the coverage and all associated memory.

  • @r None.
