Implements org.lwjgl.util.harfbuzz.hb_buffer_message_func_tI.invoke.

Doc from org.lwjgl.util.harfbuzz.hb_buffer_message_func_tI.invoke.

A callback method for hb_buffer_t. The method gets called with the hb_buffer_t it was set on, the hb_font_t the buffer is shaped with and a message describing what step of the shaping process will be performed. Returning false from this method will skip this shaping step and move to the next one.

Return value: true to perform the shaping step, false to skip it.

Parameters
buffer:long

an hb_buffer_t to work upon

font:long

the hb_font_t the buffer is shaped with

message:long

NULL-terminated message passed to the function
