Class ColumnMetadata.Raw

java.lang.Object

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

org.apache.cassandra.schema.ColumnMetadata.Raw

Enclosing class:

ColumnMetadata

public abstract static class ColumnMetadata.Raw
extends Selectable.Raw

Because legacy-created tables may have a non-text comparator, we cannot determine the proper 'key' until we know the comparator. ColumnMetadata.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.

Modifier and Type	Method and Description
boolean	equals(java.lang.Object o)
static ColumnMetadata.Raw	forColumn(ColumnMetadata column) Creates a ColumnMetadata.Raw from a pre-existing ColumnMetadata (useful in the rare cases where we already have the column but need a ColumnMetadata.Raw for typing purposes).
static ColumnMetadata.Raw	forQuoted(java.lang.String text) Creates a ColumnMetadata.Raw from a quoted identifier string.
static ColumnMetadata.Raw	forUnquoted(java.lang.String text) Creates a ColumnMetadata.Raw from an unquoted identifier string.
abstract ColumnIdentifier	getIdentifier(TableMetadata table) Get the identifier corresponding to this raw column, without assuming this is an existing column (unlike Selectable.Raw#prepare).
