Specified by:

write in interface ResourceStore

Parameters:

resourcePath - resource name of the class (format: org/objectweb/asm/Visitor.class)

bytecode - content of the resource

Throws:

IOException - if there was an error storing the resource

close

public void close()
           throws IOException

Description copied from interface: ResourceStore

Close the store: no methods will be called anymore on this instance.

Specified by:

close in interface ResourceStore

Throws:

IOException - if close failed
