  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • CODEPOINT

      public static final int CODEPOINT
      The struct member offsets.

    • MASK

      public static final int MASK
      The struct member offsets.

    • CLUSTER

      public static final int CLUSTER
      The struct member offsets.

    • VAR1

      public static final int VAR1
      The struct member offsets.

    • VAR2

      public static final int VAR2
      The struct member offsets.

  • Constructor Details

    • hb_glyph_info_t

      public hb_glyph_info_t(ByteBuffer container)
      Creates a hb_glyph_info_t instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct<hb_glyph_info_t>

    • codepoint

      public int codepoint()
      either a Unicode code point (before shaping) or a glyph index (after shaping).

    • mask

      public int mask()
      private

    • cluster

      public int cluster()
      the index of the character in the original text that corresponds to this hb_glyph_info_t, or whatever the client passes to buffer_add.

      More than one hb_glyph_info_t can have the same cluster value, if they resulted from the same character (e.g. one to many glyph substitution), and when more than one character gets merged in the same glyph (e.g. many to one glyph substitution) the hb_glyph_info_t will have the smallest cluster value of them. By default some characters are merged into the same cluster (e.g. combining marks have the same cluster as their bases) even if they are separate glyphs, buffer_set_cluster_level allow selecting more fine-grained cluster handling.

    • codepoint

      public hb_glyph_info_t codepoint(int value)
      Sets the specified value to the codepoint() field.

    • mask

      public hb_glyph_info_t mask(int value)
      Sets the specified value to the mask() field.

    • cluster

      public hb_glyph_info_t cluster(int value)
      Sets the specified value to the cluster() field.

    • set

      public hb_glyph_info_t set(int codepoint, int mask, int cluster)
      Initializes this struct with the specified values.

    • set

      public hb_glyph_info_t set(hb_glyph_info_t src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct
