Specified by:

trim in interface Trimmable

accept

public void accept(org.codice.ddf.libs.klv.KlvDataElement klvDataElement)

Description copied from interface: KlvHandler

The handler accepts the incoming KLV metadata. If the incoming KLV metadata is not the datatype expected by this handler, then the handler should log a warning and return.

Specified by:

accept in interface KlvHandler

Parameters:

klvDataElement - incoming klv metadata

reset
