Enum LiteralCapability

java.lang.Object

java.lang.Enum<LiteralCapability>

com.exasol.adapter.capabilities.LiteralCapability

All Implemented Interfaces:

Serializable, Comparable<LiteralCapability>

public enum LiteralCapability
extends Enum<LiteralCapability>

This is an enumeration of the capabilities for literals supported by the EXASOL Virtual Schema Framework.

E.g. to execute a system "SELECT * FROM t WHERE username='alice'" your data source needs the STRING capability.

Enum Constant Detail

NULL

public static final LiteralCapability NULL

The literal for null values.

Example in EXASOL syntax: NULL

BOOL

public static final LiteralCapability BOOL

The literal for boolean values.

Example in EXASOL syntax: TRUE

DATE

public static final LiteralCapability DATE

The literal for date values.

Method Detail

values

public static LiteralCapability[] 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 (LiteralCapability c : LiteralCapability.values())
    System.out.println(c);

Returns:

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

valueOf

public static LiteralCapability 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
