Enum Constant Detail

Managed

public static final QueryEngineChunkHandlerEnum Managed

Use the managed object heap (this is the historical behavior).

Native

public static final QueryEngineChunkHandlerEnum Native

Use the native heap.

Method Detail

values

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

Returns:

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

valueOf

public static QueryEngineChunkHandlerEnum 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

valueOf

public static QueryEngineChunkHandlerEnum valueOf(Class<? extends IChunkHandler> cls)

Return the type safe enumeration corresponding to a specific implementation class.

Parameters:

cls - The IChunkHandler implementation class.

Returns:

The corresponding type safe enum value.
