Enum Constant Summary

Enum Constants

Enum Constant and Description
ALIASED_SELECTOR Render the fragment as a selector with an optional alias, if required (for SELECT statements).
INTERNAL Render the fragment in internal form; for identifiers, this is the form stored in the driver's schema metadata and in the system tables, e.g.
NAMED_ASSIGNMENT Render the fragment as an assignment to a named bound variable (for INSERT, UPDATE and DELETE statements).
POSITIONAL_ASSIGNMENT Render the fragment as an assignment to a positional bound variable (for INSERT, UPDATE and DELETE statements).
UNALIASED_SELECTOR Render the fragment as an unaliased selector (for SELECT statements).
VARIABLE Render the fragment as a CQL identifier, for example, to reference a named bound variable.

Enum Constant Detail

NAMED_ASSIGNMENT

public static final CQLRenderMode NAMED_ASSIGNMENT

Render the fragment as an assignment to a named bound variable (for INSERT, UPDATE and DELETE statements). Usually this renders as :"MyVar".

POSITIONAL_ASSIGNMENT

public static final CQLRenderMode POSITIONAL_ASSIGNMENT

Render the fragment as an assignment to a positional bound variable (for INSERT, UPDATE and DELETE statements). Usually this renders as ?.

This render mode is not used anymore and was only useful when connecting with protocol version 1.

UNALIASED_SELECTOR

public static final CQLRenderMode UNALIASED_SELECTOR

Render the fragment as an unaliased selector (for SELECT statements). Usually this renders as "MyVar".

This render mode is not used anymore and was only useful when connecting with protocol * version 1.

ALIASED_SELECTOR

public static final CQLRenderMode ALIASED_SELECTOR

Render the fragment as a selector with an optional alias, if required (for SELECT statements). Usually this renders as "MyVar" AS "MyVar".

VARIABLE

public static final CQLRenderMode VARIABLE

Render the fragment as a CQL identifier, for example, to reference a named bound variable. Usually this renders as "MyVar".

INTERNAL

public static final CQLRenderMode INTERNAL

Render the fragment in internal form; for identifiers, this is the form stored in the driver's schema metadata and in the system tables, e.g. MyVar.

Method Detail

values

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

Returns:

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

valueOf

public static CQLRenderMode 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
