Description

Functions

camel_data_wrapper_new ()

CamelDataWrapper *
camel_data_wrapper_new (void);

Create a new CamelDataWrapper object.

Returns

a new CamelDataWrapper object


camel_data_wrapper_get_byte_array ()

GByteArray *
camel_data_wrapper_get_byte_array (CamelDataWrapper *data_wrapper);

Returns the GByteArray being used to hold the contents of data_wrapper .

Note, it's up to the caller to use this in a thread-safe manner.

Parameters

data_wrapper

a CamelDataWrapper

 

Returns

the GByteArray for data_wrapper .

[transfer none]

Since: 3.2


camel_data_wrapper_set_mime_type ()

void
camel_data_wrapper_set_mime_type (CamelDataWrapper *data_wrapper,
                                  const gchar *mime_type);

This sets the data wrapper's MIME type.

It might fail, but you won't know. It will allow you to set Content-Type parameters on the data wrapper, which are meaningless. You should not be allowed to change the MIME type of a data wrapper that contains data, or at least, if you do, it should invalidate the data.

Parameters

data_wrapper

a CamelDataWrapper

 

mime_type

a MIME type

 

camel_data_wrapper_get_mime_type ()

gchar *
camel_data_wrapper_get_mime_type (CamelDataWrapper *data_wrapper);

Parameters

data_wrapper

a CamelDataWrapper

 

Returns

the MIME type which must be freed by the caller


camel_data_wrapper_get_mime_type_field ()

CamelContentType *
camel_data_wrapper_get_mime_type_field
                               (CamelDataWrapper *data_wrapper);

Parameters

data_wrapper

a CamelDataWrapper

 

Returns

the parsed form of the data wrapper's MIME type.

[transfer none]


camel_data_wrapper_set_mime_type_field ()

void
camel_data_wrapper_set_mime_type_field
                               (CamelDataWrapper *data_wrapper,
                                CamelContentType *mime_type);

This sets the data wrapper's MIME type. It suffers from the same flaws as camel_data_wrapper_set_mime_type().

Parameters

data_wrapper

a CamelDataWrapper

 

mime_type

a CamelContentType

 

camel_data_wrapper_is_offline ()

gboolean
camel_data_wrapper_is_offline (CamelDataWrapper *data_wrapper);

Parameters

data_wrapper

a CamelDataWrapper

 

Returns

whether data_wrapper is "offline" (data stored remotely) or not. Some optional code paths may choose to not operate on offline data.


camel_data_wrapper_write_to_stream_sync ()

gssize
camel_data_wrapper_write_to_stream_sync
                               (CamelDataWrapper *data_wrapper,
                                CamelStream *stream,
                                GCancellable *cancellable,
                                GError **error);

Writes the content of data_wrapper to stream in a machine-independent format appropriate for the data. It should be possible to construct an equivalent data wrapper object later by passing this stream to camel_data_wrapper_construct_from_stream_sync().

This function may block even if the given output stream does not. For example, the content may have to be fetched across a network before it can be written to stream.

Parameters

data_wrapper

a CamelDataWrapper

 

stream

a CamelStream for output

 

cancellable

optional GCancellable object, or NULL

 

error

return location for a GError, or NULL

 

Returns

the number of bytes written, or -1 on error

Since: 3.0


camel_data_wrapper_write_to_stream ()

void
camel_data_wrapper_write_to_stream (CamelDataWrapper *data_wrapper,
                                    CamelStream *stream,
