Method Detail

values

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

Returns:

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

valueOf

public static NodeType 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

isHost

public boolean isHost()

isConfigServerLike

public boolean isConfigServerLike()

either config server or controller

isConfigServerHostLike

public boolean isConfigServerHostLike()

either config server host or controller host

isSharable

public boolean isSharable()

Returns whether this supports host sharing

description

public String description()

childNodeType

public NodeType childNodeType()

Returns:

NodeType of the node(s) that run on this host

Throws:

IllegalStateException - if this type is not a host

childNodeTypes

public List<NodeType> childNodeTypes()

Returns:

all NodeTypes that can run on this host

Throws:

IllegalStateException - if this type is not a host

canRun

public boolean canRun(NodeType type)

Returns whether given node type can run on this

hostType

public NodeType hostType()

Returns the host type of this
