Constructor Details

ObjectSqlType

public ObjectSqlType(SqlTypeName typeName,
 @Nullable SqlIdentifier sqlIdentifier,
 boolean nullable,
 List<? extends RelDataTypeField> fields,
 RelDataTypeComparability comparability)

Constructs an object type. This should only be called from a factory method.

Parameters:

typeName - SqlTypeName for this type (either Distinct or Structured)

sqlIdentifier - identifier for this type

nullable - whether type accepts nulls

fields - object attribute definitions

Method Details

setFamily

public void setFamily(RelDataTypeFamily family)

getComparability

public RelDataTypeComparability getComparability()

Description copied from interface: RelDataType

Returns the category of comparison operators that make sense when applied to values of this type.

Specified by:

getComparability in interface RelDataType

Overrides:

getComparability in class RelDataTypeImpl

getSqlIdentifier

public @Nullable SqlIdentifier getSqlIdentifier()

Description copied from interface: RelDataType

Gets the SqlIdentifier associated with this type. For a predefined type, this is a simple identifier based on RelDataType.getSqlTypeName(). For a user-defined type, this is a compound identifier which uniquely names the type.

Specified by:

getSqlIdentifier in interface RelDataType

Overrides:

getSqlIdentifier in class RelDataTypeImpl

Returns:

SqlIdentifier, or null if this is not an SQL type

getFamily

public RelDataTypeFamily getFamily()

Description copied from interface: RelDataType

Gets a canonical object representing the family of this type. Two values can be compared if and only if their types are in the same family.

Specified by:

getFamily in interface RelDataType

Overrides:

getFamily in class AbstractSqlType

Returns:

canonical object representing type family, never null

generateTypeString

protected void generateTypeString(StringBuilder sb,
 boolean withDetail)

Description copied from class: RelDataTypeImpl

Generates a string representation of this type.

Specified by:

generateTypeString in class RelDataTypeImpl

Parameters:

sb - StringBuilder into which to generate the string

withDetail - when true, all detail information needed to compute a unique digest (and return from getFullTypeString) should be included;
