Method Detail

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 - StringBuffer 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;

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
