#size ⇒ Integer
Queries the size in bytes of the data stored in the blob.

Constructor Details

#initialize(size, data_to_copy) ⇒ `Gsf::Blob`

Creates a new Gsf::Blob object to hold the specified data. The blob can then
be used as a facility for reference-counting for the data. The data is
copied internally, so the blob does not hold references to external chunks
of memory.
Data which will be copied into the blob, or nil if size is zero.
Error domain: #GSF_ERROR

Possible errors: #GSF_ERROR_OUT_OF_MEMORY if the data_to_copy could not be copied.

Parameters:

size (Integer) —
Size of the data in bytes.
data_to_copy (Array<Integer>)

Instance Method Details

#peek_data ⇒ `GObject`

Queries a pointer to the data stored in the blob. This does not
copy the data for you; it returns a pointer to the actual buffer
which the blob uses internally, so you should not free this buffer
on your own.
blob, or nil if the size of the data is zero.
