Method Detail

values

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

Returns:

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

valueOf

public static GridComponentType 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

className

public String className()

Returns:

Component class name.

create

public <T extends GridComponent> T create(GridKernalContext ctx,
                                 boolean noOp)
                               throws GridException

Creates component.

Parameters:

ctx - Kernal context.

noOp - No-op flag.

Returns:

Created component.

Throws:

GridException - If failed.

create

public <T> T create(boolean noOp)
         throws GridException

Creates component.

Parameters:

noOp - No-op flag.

Returns:

Created component.

Throws:

GridException - If failed.

createOptional

public <T> T createOptional(GridKernalContext ctx)
                 throws GridException

First tries to find main component class, if it is not found creates no-op implementation.

Parameters:

ctx - Kernal context.

Returns:

Created component or no-op implementation.

Throws:

GridException - If failed.

createOptional

public <T> T createOptional()
                 throws GridException

First tries to find main component class, if it is not found creates no-op implementation.

Returns:

Created component or no-op implementation.

Throws:

GridException - If failed.
