public void markOverweavingInUse() If the weaver is ever invoked in over weaving mode, we should not include the key when writing out, it won't be replaced later. If we turn off the reweaving flag that unfortunately removes the 'what aspects have been woven into this type' list which we want to keep as it helps overweaving avoid weaving an aspect in twice.

Returns:String: a string representation of the object.

write

back to summary

public void write(CompressingDataOutputStream s) throws IOException

Serialize the WeaverStateInfo. Various bits are set within the 'kind' flag to indicate the structure of the attribute. In reweavable diff mode a 'marker' is inserted at the start of the attribute to indicate where the final calculated diff should be inserted. When the key is replaced with the diff, the 'kind' byte moves to the front of the attribute - thats why in the read logic you'll see it expecting the kind as the first byte.
