class: HarfBuzzFeaturet

[34:7] extends: object

The #hb_feature_t is the structure that holds information about requested feature application. The feature will be applied with the given value to all glyphs which are in clusters between @start (inclusive) and @end (exclusive). Setting start to #HB_FEATURE_GLOBAL_START and end to #HB_FEATURE_GLOBAL_END specifies that the feature always applies to the entire buffer.

Methods

HarfBuzzFeaturet (Handle = null)

Creates a new feature_t by wrapping a native handle or another wrapper.
- @p Handle is the native handle or another wrapper whose handle to adopt.
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.
_string ()

Converts a #hb_feature_t into a NULL-terminated string in the format understood by hb_feature_from_string(). The client in responsible for allocating big enough size for @buf, 128 bytes is more than enough. Note that the feature value will be omitted if it is '1', but the string won't include any whitespace.
- @p buf is output string.
- @p size is the allocated size of @buf.
- @r None.
