org.springframework.cassandra.core.cql.CqlIdentifier
This encapsulates the logic for CQL quoted and unquoted identifiers.
CQL identifiers, when unquoted, are converted to lower case. When quoted, they are returned as-is with no lower casing and encased in double quotes. To render, use any of the methods {@link #toCql()}, {@link #toCql(StringBuilder)}, or {@link #toString()}. @see #CqlIdentifier(String) @see #CqlIdentifier(String,boolean) @see #toCql() @see #toCql(StringBuilder) @see #toString() @author John McPeek @author Matthew T. Adams
