Method Detail

values

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

Returns:

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

valueOf

public static IgniteComponentType 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.

module

public String module()

Returns:

Component module name.

inClassPath

public boolean inClassPath()

Check whether real component class is in classpath.

Returns:

True if in classpath.

create

public <T> T create(GridKernalContext ctx,
                    boolean noOp)
             throws IgniteCheckedException

Creates component.

Parameters:

ctx - Kernal context.

noOp - No-op flag.

Returns:

Created component.

Throws:

IgniteCheckedException - If failed.

createIfInClassPath

public <T> T createIfInClassPath(GridKernalContext ctx,
                                 boolean mandatory)
                          throws IgniteCheckedException

Creates component.

Parameters:

ctx - Kernal context.

mandatory - If the component is mandatory.

Returns:

Created component.

Throws:

IgniteCheckedException - If failed.

create

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

Creates component.

Parameters:

noOp - No-op flag.

Returns:

Created component.

Throws:

IgniteCheckedException - If failed.

createOptional

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

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:

IgniteCheckedException - If failed.

createOptional

public <T> T createOptional()
                     throws IgniteCheckedException

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

Returns:

Created component or no-op implementation.

Throws:

IgniteCheckedException - If failed.

messageFactory

@Nullable
public @Nullable MessageFactoryProvider messageFactory()
                                                throws IgniteCheckedException

Creates message factory for the component.

Returns:

Message factory or null if none or the component is not in classpath.

Throws:

IgniteCheckedException - If failed.
