Uses of ColumnCapabilities.Capable in org.apache.druid.segment.column

Methods in org.apache.druid.segment.column that return ColumnCapabilities.Capable

Modifier and Type	Method	Description
ColumnCapabilities.Capable	ColumnCapabilities.Capable.and(ColumnCapabilities.Capable other)
ColumnCapabilities.Capable	ColumnCapabilities.areDictionaryValuesSorted()	If the column is dictionary encoded, are those values sorted? Useful to know for optimizations that can defer looking up values and allowing sorting with the dictionary ids directly.
ColumnCapabilities.Capable	ColumnCapabilitiesImpl.areDictionaryValuesSorted()
ColumnCapabilities.Capable	ColumnCapabilities.areDictionaryValuesUnique()	If the column is dictionary encoded, is there a 1:1 mapping of dictionary ids to values? If this is true, it unlocks optimizations such as allowing for things like grouping directly on dictionary ids and deferred value lookup.
ColumnCapabilities.Capable	ColumnCapabilitiesImpl.areDictionaryValuesUnique()
ColumnCapabilities.Capable	ColumnCapabilities.Capable.coerceUnknownToBoolean(boolean unknownIsTrue)
ColumnCapabilities.Capable	ColumnCapabilities.hasMultipleValues()	String columns are sneaky, and might have multiple values, this is to allow callers to know and appropriately prepare themselves.
ColumnCapabilities.Capable	ColumnCapabilitiesImpl.hasMultipleValues()
ColumnCapabilities.Capable	ColumnCapabilities.hasNulls()	Does this column contain null values? If so, callers, especially for primitive numeric columns, will need to check for null value rows and act accordingly.
ColumnCapabilities.Capable	ColumnCapabilitiesImpl.hasNulls()
ColumnCapabilities.Capable	ColumnCapabilities.isDictionaryEncoded()	Is the column dictionary encoded? If so, a DimensionDictionarySelector may be used instead of using a value selector, allowing algorithms to operate on primitive integer dictionary ids rather than the looked up dictionary values.
ColumnCapabilities.Capable	ColumnCapabilitiesImpl.isDictionaryEncoded()
static ColumnCapabilities.Capable	ColumnCapabilities.Capable.of(boolean bool)
static ColumnCapabilities.Capable	ColumnCapabilities.Capable.ofNullable(Boolean bool)
ColumnCapabilities.Capable	ColumnCapabilities.Capable.or(ColumnCapabilities.Capable other)
static ColumnCapabilities.Capable	ColumnCapabilities.Capable.valueOf(String name)	Returns the enum constant of this type with the specified name.
static ColumnCapabilities.Capable[]	ColumnCapabilities.Capable.values()	Returns an array containing the constants of this enum type, in the order they are declared.
