Base class for blob sources.

A BaseBlobSource provides BaseBlob instances.

Method	`get_blob`	Return a blob.
Method	`get_size`	Get the size of a blob from this factory.

def get_blob(self): ¶

overridden in pyzim.blob.EmptyBlobSource, pyzim.blob.EntryBlobSource, pyzim.blob.FileBlobSource, pyzim.blob.InMemoryBlobSource

Return a blob.

Returns
`BaseBlob`	a fresh instance of a subclass of `BaseBlob`

def get_size(self): ¶

overridden in pyzim.blob.EmptyBlobSource, pyzim.blob.EntryBlobSource, pyzim.blob.FileBlobSource, pyzim.blob.InMemoryBlobSource

Get the size of a blob from this factory.

The default implementation instantiates a new blob using BaseBlobSource.get_blob and calls BaseBlob.get_size. Subclasses may overwrite this method for a more efficient implementation.

Please See BaseBlob.get_size for details.

Returns
`int`	the size of a blob in byzes
