Method Detail

id

public DiscreteResourceId id()

Description copied from interface: Resource

Returns the ID of this resource.

Specified by:

id in interface Resource

Returns:

the ID of this resource

simpleTypeName

public String simpleTypeName()

Description copied from interface: Resource

Returns the simple type name of this resource. Example:
Resource: DeviceId:1/PortNumber:1/VlanId:200
Simple type name: VlanId

Specified by:

simpleTypeName in interface Resource

Returns:

the simple type name of this resource

isTypeOf

public boolean isTypeOf(Class<?> type)

Description copied from interface: Resource

Checks if the type of this instance is the specified type.

Specified by:

isTypeOf in interface Resource

Parameters:

type - type of resource to be checked

Returns:

true if this resource is the type of the specified type. Otherwise, false.

isSubTypeOf

public boolean isSubTypeOf(Class<?> ancestor)

Description copied from interface: Resource

Checks if the type of this instance is the sub-type of the specified type.

Specified by:

isSubTypeOf in interface Resource

Parameters:

ancestor - type of resource to be checked.

Returns:

true if this resource is under the resource whose type is the given type.

valueAs

public <T> Optional<T> valueAs(Class<T> type)

Description copied from interface: Resource

Returns value interpreted as the specified type. If the specified type is incompatible with the underlying value, an empty instance is returned.

Specified by:

valueAs in interface Resource

Type Parameters:

T - type of the return value

Parameters:

type - class instance specifying the type of return value

Returns:

the value of this resource as the specified type. If type mismatches, returns an empty instance.

child

public DiscreteResource child(Object child)

Description copied from interface: Resource

Returns a child resource of this instance with specifying the child object. It is not allowed that a continuous type resource has a child. If the instance is ContinuousResource, UnsupportedOperationException is thrown. If the given object is a Class instance, IllegalArgumentException is thrown.

Specified by:

child in interface Resource

Parameters:

child - child object

Returns:

a child resource

child

public ContinuousResource child(Class<?> child,
                                double value)

Description copied from interface: Resource

Returns a child resource of this instance with specifying a child object and value. It is not allowed that a continuous type resource has a child. If the instance is ContinuousResource, UnsupportedOperationException is thrown.

Specified by:

child in interface Resource

Parameters:

child - child object

value - value

Returns:

a child resource

parent

public Optional<DiscreteResource> parent()

Description copied from interface: Resource

Returns the parent resource of this instance. E.g. if this resource is Link:1/VLAN ID:100, the return value is the resource for Link:1.

Specified by:

parent in interface Resource

Returns:

the parent resource of this instance. If there is no parent, empty instance will be returned.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
