Description

Functions

IDE_TYPE_BUFFER

#define IDE_TYPE_BUFFER (ide_buffer_get_type ())

ide_buffer_get_busy ()

gboolean
ide_buffer_get_busy (IdeBuffer *self);

Gets the “busy” property. Return whether the buffer is performing background work or not.

Parameters

self

A IdeBuffer.

 

Returns

TRUE if the IdeBuffer is performing background work. Otherwise FALSE.


ide_buffer_get_changed_on_volume ()

gboolean
ide_buffer_get_changed_on_volume (IdeBuffer *self);

Gets if the file backing the buffer has changed on the underlying storage.

Use ide_buffer_manager_load_file_async() to reload the buffer.

Parameters

self

A IdeBuffer.

 

Returns

TRUE if the file has changed.


ide_buffer_get_change_count ()

gsize
ide_buffer_get_change_count (IdeBuffer *self);

ide_buffer_get_content ()

GBytes *
ide_buffer_get_content (IdeBuffer *self);

Gets the contents of the buffer as GBytes.

By using this function to get the bytes, you allow IdeBuffer to avoid calculating the buffer text unnecessarily, potentially saving on allocations.

Additionally, this allows the buffer to update the state in IdeUnsavedFiles if the content is out of sync.

Parameters

self

A IdeBuffer.

 

Returns

A GBytes containing the buffer content.
