Uses of TypeDescriptor in org.apache.druid.segment.column

Classes in org.apache.druid.segment.column with type parameters of type TypeDescriptor

Modifier and Type	Class	Description
class	BaseTypeSignature<Type extends TypeDescriptor>
interface	TypeFactory<Type extends TypeSignature<? extends TypeDescriptor>>	Create TypeSignature of a TypeDescriptor.
interface	TypeSignature<Type extends TypeDescriptor>	This interface serves as a common foundation for Druids native type system, and provides common methods for reasoning about and handling type matters.

Classes in org.apache.druid.segment.column that implement TypeDescriptor

Modifier and Type	Class	Description
class	ValueType	This enumeration defines the high level classification of the Druid type system, used by ColumnType to indicate the type of data stored in columns and produced by expressions and aggregations, used to allow query processing engine algorithms to compute results, used to compute query result row signatures, and all other type needs.

Methods in org.apache.druid.segment.column with type parameters of type TypeDescriptor

Modifier and Type	Method	Description
static <T extends TypeDescriptor> boolean	Types.either(TypeSignature<T> typeSignature1, TypeSignature<T> typeSignature2, T typeDescriptor)	Returns true if either supplied TypeSignature.getType() is the given TypeDescriptor Useful for choosing a common TypeDescriptor between two TypeSignature when one of the signatures might be null.
static <T extends TypeDescriptor> boolean	Types.is(TypeSignature<T> typeSignature, T typeDescriptor)	Returns true if TypeSignature.getType() is of the specified TypeDescriptor
static <T extends TypeDescriptor> boolean	Types.isNullOr(TypeSignature<T> typeSignature, T typeDescriptor)	Returns true if TypeSignature.getType() is null, or of the specified TypeDescriptor
static <T extends TypeDescriptor> boolean	Types.isNullOrAnyOf(TypeSignature<T> typeSignature, T... typeDescriptors)	Returns true if the TypeSignature is null, or is any one of the specified TypeDescriptor
static <T extends TypeDescriptor> boolean	Types.isNumeric(TypeSignature<T> typeSignature)	Returns true if TypeSignature is not null and is TypeSignature.isNumeric()
static <T extends TypeDescriptor> boolean	Types.isNumericOrNumericArray(TypeSignature<T> typeSignature)	Returns true if TypeSignature is not null and is TypeSignature.isNumeric() or has TypeSignature.getElementType() that is numeric.

Methods in org.apache.druid.segment.column with parameters of type TypeDescriptor

Modifier and Type	Method	Description
default boolean	TypeSignature.anyOf(Type... types)	Check if the value of TypeSignature.getType() matches any of the TypeDescriptor specified.
static <T extends TypeDescriptor> boolean	Types.isNullOrAnyOf(TypeSignature<T> typeSignature, T... typeDescriptors)	Returns true if the TypeSignature is null, or is any one of the specified TypeDescriptor
