Examples of OverflowBlob

org.apache.axiom.util.blob.OverflowBlob
Blob implementation that stores data in a temporary file if the size exceeds a configurable threshold. The data is first stored into a fixed size buffer. Once this buffer overflows, it is transferred to a temporary file. The buffer is divided into a given number of fixed size chunks that are allocated on demand. Since a temporary file may be created it is mandatory to call {@link #release()} to discard the blob.
