cloneTags

default byte[] cloneTags()

Allows cloning the tags in the cell to a new byte[]

Returns:

the byte[] having the tags

getTags

default Iterator<Tag> getTags()

Creates a list of tags in the current cell

Returns:

a list of tags

getTag

default Optional<Tag> getTag(byte type)

Returns the specific tag of the given type

Parameters:

type - the type of the tag

Returns:

the specific tag if available or null

checkForTagsLength
