Package org.apache.calcite.rel.type

Defines a type system for relational expressions.

See: Description

Interface Summary

Interface	Description
RelDataType	RelDataType represents the type of a scalar expression or entire row returned from a relational expression.
RelDataTypeFactory	RelDataTypeFactory is a factory for datatype descriptors.
RelDataTypeFactory.FieldInfo	Deprecated
RelDataTypeFamily	RelDataTypeFamily represents a family of related types.
RelDataTypeField	RelDataTypeField represents the definition of a field in a structured RelDataType.
RelDataTypePrecedenceList	RelDataTypePrecedenceList defines a type precedence list for a particular type.
RelDataTypeSystem	Type system.
RelProtoDataType	Can be converted into a RelDataType given a RelDataTypeFactory.

Class Summary

Class	Description
DynamicRecordType	Specific type of RelRecordType that corresponds to a dynamic table, where columns are created as they are requested.
DynamicRecordTypeImpl	Implementation of RelDataType for a dynamic table.
RelCrossType	Type of the cartesian product of two or more sets of records.
RelDataTypeFactory.Builder	Fluid API to build a list of fields.
RelDataTypeFactory.FieldInfoBuilder	Deprecated
RelDataTypeFactoryImpl	Abstract base for implementations of RelDataTypeFactory.
RelDataTypeFactoryImpl.Key	Key to the data type cache.
RelDataTypeField.ToFieldIndex	Function to transform a set of RelDataTypeField to a set of Integer of the field keys.
RelDataTypeField.ToFieldName	Function to transform a set of RelDataTypeField to a set of String of the field names.
RelDataTypeFieldImpl	Default implementation of RelDataTypeField.
RelDataTypeHolder	Holding the expandable list of fields for dynamic table.
RelDataTypeImpl	RelDataTypeImpl is an abstract base for implementations of RelDataType.
RelDataTypeImpl.Slot	Work space for RelDataTypeImpl.getFieldRecurse(java.util.List<org.apache.calcite.rel.type.RelDataTypeImpl.Slot>, org.apache.calcite.rel.type.RelDataType, int, java.lang.String, boolean).
RelDataTypeSystemImpl	Default implementation of RelDataTypeSystem, providing parameters from the SQL standard.
RelRecordType	RelRecordType represents a structured type having named fields.
RelRecordType.SerializableRelRecordType	Skinny object which has the same information content as a RelRecordType but skips redundant stuff like digest and the immutable list.

Enum Summary

Enum	Description
RelDataTypeComparability	RelDataTypeComparability is an enumeration of the categories of comparison operators which types may support.
StructKind	Describes a policy for resolving fields in record types.
