This function is typically used when reading configuration files or other non-user input that should be locale independent.

                          const GValue *from);

Sets the value of a GValue from another GValue. This is different from gda_value_copy, which creates a new GValue. gda_value_set_from_value, on the other hand, copies the contents of copy into value , which must already be allocated.

If values are incompatible (see g_value_type_compatible ) then value is set to a GDA_TYPE_NULL, and FALSE is returned.

gda_value_compare ()

gint
gda_value_compare (const GValue *value1,
                   const GValue *value2);

Converts a GValue to its string representation which is a human readable value. Note that the returned string does not take into account the current locale of the user (on the contrary to the GdaDataHandler objects). Using this function should be limited to debugging and values serialization purposes.

Output is in the "C" locale for numbers, and dates are converted in a YYYY-MM-DD format.

gda_value_to_xml ()

xmlNodePtr
gda_value_to_xml (const GValue *value);

Serializes the given GValue to an XML node string.

[skip]

gda_binary_to_string ()

gchar *
gda_binary_to_string (const GdaBinary *bin,
                      guint maxlen);

Converts all the non printable characters of bin->data into the "\xyz" representation where "xyz" is the octal representation of the byte, and the '\' (backslash) character is converted to "\". Printable characters (defined by g_ascii_isprint()) as well as newline character are not converted.

Note that the backslash and newline characters are considered as printable characters and will not be represented by the "\xyz" representation.

Use this function to get a representation as much readable by humans as possible of a binary chunk. Note that this function is internally called when transforming a binary value to a string for example when using g_value_transform() or gda_value_stringify().

gda_string_to_binary ()

GdaBinary *
gda_string_to_binary (const gchar *str);

Performs the reverse of gda_binary_to_string() (note that for any "\xyz" succession of 4 characters where "xyz" represents a valid octal value, the resulting read value will be modulo 256).

I str is NULL, then an empty (i.e. where the data part is NULL) GdaBinary is created and returned.

gda_blob_to_string ()

gchar *
gda_blob_to_string (GdaBlob *blob,
                    guint maxlen);

Converts all the non printable characters of blob->data into the \xxx representation where xxx is the octal representation of the byte, and the '\' (backslash) character is converted to "\".

gda_string_to_blob ()

GdaBlob *
gda_string_to_blob (const gchar *str);
