Signal

IdePipelineStage::query

Declaration 

void
query (
  IdePipelineStage* self,
  IdePipeline* pipeline,
  gpointer targets,
  GCancellable* cancellable,
  gpointer user_data
)

Description

The IdePipelineStage::query signal is emitted to request that the build stage update its completed stage from any external resources.

This can be useful if you want to use an existing build stage instances and use a signal to pause forward progress until an external system has been checked.

The targets that the user would like to ensure are built are provided as targets. Some IdePipelineStage may use this to reduce the amount of work they perform

For example, in a signal handler, you may call ide_pipeline_stage_pause() and perform an external operation. Forward progress of the stage will be paused until a matching number of ide_pipeline_stage_unpause() calls have been made.

Default handler:

The default handler is called after the handlers added via g_signal_connect().
