Constructor Details

MultisetSqlType

public MultisetSqlType(RelDataType elementType,
 boolean isNullable)

Constructs a new MultisetSqlType. This constructor should only be called from a factory method.

Method Details

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;

deepEquals

public boolean deepEquals(@Nullable Object obj)

Description copied from interface: RelDataType

Deep equality check for RelDataType digest.

Specified by:

deepEquals in interface RelDataType

Overrides:

deepEquals in class RelDataTypeImpl

Returns:

Whether the 2 RelDataTypes are equivalent or have the same digest.

See Also:

• RelDataType.deepHashCode()

deepHashCode

public int deepHashCode()

Description copied from interface: RelDataType

Compute deep hash code for RelDataType digest.

Specified by:

deepHashCode in interface RelDataType

Overrides:

deepHashCode in class RelDataTypeImpl

See Also:

• RelDataType.deepEquals(Object)

getComponentType

public RelDataType getComponentType()

Description copied from interface: RelDataType

Gets the component type if this type is a collection, otherwise null.

Specified by:

getComponentType in interface RelDataType

Overrides:

getComponentType in class RelDataTypeImpl

Returns:

canonical type descriptor for components

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

getPrecedenceList

public RelDataTypePrecedenceList getPrecedenceList()

Description copied from interface: RelDataType

Returns the precedence list for this type.

Specified by:

getPrecedenceList in interface RelDataType

Overrides:

getPrecedenceList in class AbstractSqlType
