question: position the stream so that a valid operation can be read from it with readop . this method can be used to skip over corrupted sections of edit logs . concode_field_sep FSEditLogOp cachedOp concode_field_sep int getVersion concode_elem_sep boolean isLocalLog concode_elem_sep long getFirstTxId concode_elem_sep String getName concode_elem_sep long scanNextOp concode_elem_sep String getCurrentStreamName concode_elem_sep void setMaxOpSize concode_elem_sep FSEditLogOp nextOp concode_elem_sep long length concode_elem_sep FSEditLogOp nextValidOp concode_elem_sep FSEditLogOp readOp concode_elem_sep long getPosition concode_elem_sep boolean skipUntil concode_elem_sep long getLastTxId concode_elem_sep FSEditLogOp getCachedOp concode_elem_sep void close concode_elem_sep boolean isInProgress
target: void function ( ) { if ( cachedOp != null ) { return ; } cachedOp = nextValidOp ( ) ; }
