Subject [jira] Commented: (CASSANDRA-2262) use o.a.c.marshal.*Type for CQL
Date Wed, 02 Mar 2011 21:09:36 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13001645#comment-13001645

Gary Dusbabek commented on CASSANDRA-2262:
------------------------------------------

bq. Why is that?
It didn't follow naturally for me.  But I suppose if we don't use hex, there are a great many
byte arrays that have no real string representation.  It seems less silly now.

> Presently, {{o.a.c.cql.Term.getByteBuffer}} manage's the conversion from a parsed term
to a {{ByteBuffer}} of the right contents, this should be moved into the individual {{AbstractType}}
subclasses (aka {{AbstractType.fromString}}).
> Additionally, a method that does the inverse (returning the string equivalent), needs
to exists such that {{AbstractType.getString(AbstractType.fromString(s)) == s}}
> Finally, for use in results decoding a method should exist that given a {{ByteBuffer}}
will return the appropriate object for that type.  For example, {{IntegerType.compose(ByteBuffer)
-> java.math.BigInteger}}, or {{LexicalUUIDType.compose(ByteBuffer) -> java.util.UUID}}.
