InfTextChunk * inf_text_chunk_new (const gchar *encoding);
Creates a new InfTextChunk with no initial content that holds text
in the given encoding. TODO: Allow binary data with NULL encoding.
|
A content encoding, such as "UTF-8" or "LATIN1". |
Returns : |
A new InfTextChunk. |
InfTextChunk * inf_text_chunk_copy (InfTextChunk *self);
Returns a copy of self.
|
A InfTextChunk. |
Returns : |
A new InfTextChunk. |
void inf_text_chunk_free (InfTextChunk *self);
Frees a InfTextChunk allocated with inf_text_chunk_new(),
inf_text_chunk_copy() or inf_text_chunk_substring().
|
A InfTextChunk. |
const gchar * inf_text_chunk_get_encoding (InfTextChunk *self);
Returns the character encoding in which the content of self is encoded.
|
A InfTextChunk. |
Returns : |
The encoding of self.
|
guint inf_text_chunk_get_length (InfTextChunk *self);
Returns the number of characters contained in self.
|
A InfTextChunk. |
Returns : |
The number of characters of self.
|
InfTextChunk * inf_text_chunk_substring (InfTextChunk *self, guint begin, guint length);
Returns a new InfTextChunk containing a substring of self, beginning
at character offset begin and length characters long.
|
A InfTextChunk. |
|
A character offset into self.
|
|
The length of the text to extract. |
Returns : |
A new InfTextChunk. |
void inf_text_chunk_insert_text (InfTextChunk *self, guint offset, gconstpointer text, gsize bytes, guint length, guint author);
Inserts text written by author into self. text is expected to be in
the chunk's encoding.
|
A InfTextChunk. |
|
Character offset at which to insert text |
|
Text to insert. |
|
Number of bytes of text.
|
|
Number of characters contained in text.
|
|
User that wrote text.
|
void inf_text_chunk_insert_chunk (InfTextChunk *self, guint offset, InfTextChunk *text);
Inserts text into self at position offset. text and self must
have the same encoding.
|
A InfTextChunk. |
|
Character offset at which to insert text. |
|
Chunk to insert into self.
|
void inf_text_chunk_erase (InfTextChunk *self, guint begin, guint length);
Removes length characters of self, starting from character offset begin.
|
A InfTextChunk. |
|
A character offset into self.
|
|
Number of characters to erase. |
gpointer inf_text_chunk_get_text (InfTextChunk *self, gsize *length);
Returns the content of self as an array. The text is encoded in
self's encoding. length is set to the number of bytes in the returned
buffer, if non-NULL. The result is _not_ zero-terminated.
|
A InfTextChunk. |
|
Location to write the number of bytes to, or NULL.
|
Returns : |
Content of self. Free with g_free() if no longer in use.
|
gboolean inf_text_chunk_equal (InfTextChunk *self, InfTextChunk *other);
Returns whether the two text chunks contain the same text and the same segments were written by the same authors.
|
A InfTextChunk. |
|
Another InfTextChunk. |
Returns : |
Whether the two chunks are equal. |
gboolean inf_text_chunk_iter_init (InfTextChunk *self, InfTextChunkIter *iter);
Sets iter to point to the first segment of self. If there are no
segments (i.e. self is empty), iter is left untouched and the function
returns FALSE.
|
A InfTextChunk. |
|
A InfTextChunkIter. |
Returns : |
Whether iter was set.
|
gboolean inf_text_chunk_iter_next (InfTextChunkIter *iter);
Sets iter to point to the next segment. If iter already points to the
last segment, the function returns FALSE.
|
An initialized InfTextChunkIter. |
Returns : |
Whether iter was set.
|
gboolean inf_text_chunk_iter_prev (InfTextChunkIter *iter);
Sets iter to point to the previous segment. If iter already points to
the first segment, the function returns FALSE.
|
An initialized InfTextChunkIter. |
Returns : |
Whether iter has changed.
|
gconstpointer inf_text_chunk_iter_get_text (InfTextChunkIter *iter);
Returns the text of the segment iter points to. The text is in the
underlaying InfTextChunk's encoding.
|
An initialized InfTextChunkIter. |
Returns : |
The text of the segment iter points to.
|
guint inf_text_chunk_iter_get_length (InfTextChunkIter *iter);
Returns the number of characters in the segment iter points to.
|
An initialized InfTextChunkIter. |
Returns : |
The number of characters in the segment iter points to.
|
gsize inf_text_chunk_iter_get_bytes (InfTextChunkIter *iter);
Returns the number of bytes in the segment iter points to.
|
An initialized InfTextChunkIter. |
Returns : |
The number of bytes in the segment iter points to.
|
guint inf_text_chunk_iter_get_author (InfTextChunkIter *iter);
Returns the user ID of the author of the segment iter points to.
|
An initialized InfTextChunkIter. |
Returns : |
The user ID of the author of the segment iter points to.
