Class ColumnDefinition.Raw

java.lang.Object

org.apache.cassandra.cql3.selection.Selectable.Raw

org.apache.cassandra.config.ColumnDefinition.Raw

Enclosing class:

ColumnDefinition

public abstract static class ColumnDefinition.Raw
extends Selectable.Raw

Because Thrift-created tables may have a non-text comparator, we cannot determine the proper 'key' until we know the comparator. ColumnDefinition.Raw is a placeholder that can be converted to a real ColumnIdentifier once the comparator is known with prepare(). This should only be used with identifiers that are actual column names. See CASSANDRA-8178 for more background.

Method Summary

Modifier and Type	Method and Description
boolean	equals(java.lang.Object o)
static ColumnDefinition.Raw	forColumn(ColumnDefinition column) Creates a ColumnDefinition.Raw from a pre-existing ColumnDefinition (useful in the rare cases where we already have the column but need a ColumnDefinition.Raw for typing purposes).
static ColumnDefinition.Raw	forQuoted(java.lang.String text) Creates a ColumnDefinition.Raw from a quoted identifier string.
static ColumnDefinition.Raw	forUnquoted(java.lang.String text) Creates a ColumnDefinition.Raw from an unquoted identifier string.
abstract ColumnIdentifier	getIdentifier(CFMetaData cfm) Get the identifier corresponding to this raw column, without assuming this is an existing column (unlike prepare(org.apache.cassandra.config.CFMetaData)).
int	hashCode()
abstract ColumnDefinition	prepare(CFMetaData cfm)
boolean	processesSelection() Returns true if any processing is performed on the selected column.
