Method Summary

Modifier and Type	Method	Description
void	run(@Nullable TextIter iter, BracketMatchType state)	iter is set to a valid iterator pointing to the matching bracket if state is BracketMatchType.FOUND.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, int) method.
default void	upcall(MemorySegment sourceBuffer, MemorySegment iter, int state)	The upcall method is called from native code.

Method Details

run

void run(@Nullable
 @Nullable TextIter iter,
 BracketMatchType state)

iter is set to a valid iterator pointing to the matching bracket if state is BracketMatchType.FOUND. Otherwise iter is meaningless.

The signal is emitted only when the state changes, typically when the cursor moves.

A use-case for this signal is to show messages in a Statusbar.

upcall

default void upcall(MemorySegment sourceBuffer,
 MemorySegment iter,
 int state)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gtk.TextIter, org.gnome.gtksourceview.BracketMatchType) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, int) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
