Enum LogicalTypeFamily

java.lang.Object

java.lang.Enum<LogicalTypeFamily>

org.apache.flink.table.types.logical.LogicalTypeFamily

All Implemented Interfaces:

Serializable, Comparable<LogicalTypeFamily>

@PublicEvolving
public enum LogicalTypeFamily
extends Enum<LogicalTypeFamily>

An enumeration of logical type families for clustering LogicalTypeRoots into categories.

The enumeration is very close to the SQL standard in terms of naming and completeness. However, it reflects just a subset of the evolving standard and contains some extensions (indicated by EXTENSION).

Method Detail

values

public static LogicalTypeFamily[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LogicalTypeFamily c : LogicalTypeFamily.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LogicalTypeFamily valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
