Class ContentType<T>

java.lang.Object

org.openjdk.jmc.common.unit.ContentType<T>

Type Parameters:

T - the type of values that the content type is used for

All Implemented Interfaces:

IDescribable, IType<T>

Direct Known Subclasses:

KindOfQuantity, StructContentType

public class ContentType<T>
extends Object
implements IType<T>

A content type describes what kind of data a value is. It's not specific unit, like seconds/minutes or bytes/MB, but it could be time or memory.

Data values of the same content type should be able share a single axis in a graph.

Method Detail

addFormatter

protected void addFormatter(DisplayFormatter<T> formatter)

getFormatters

public List<DisplayFormatter<T>> getFormatters()

getDefaultFormatter

public IFormatter<T> getDefaultFormatter()

getName

public String getName()

Specified by:

getName in interface IDescribable

Returns:

the name of this object

getIdentifier

public String getIdentifier()

Description copied from interface: IType

String identifying the type. It must never be localized and it should only contain characters that are safe to use in various configuration files, e.g. in XML.

Specified by:

getIdentifier in interface IType<T>

Returns:

type identifier

getPersister

public IPersister<T> getPersister()

getFormatter

public IFormatter<T> getFormatter(String formatterIdentifier)

getDescription

public String getDescription()

Specified by:

getDescription in interface IDescribable

Returns:

the description of this object

getAttributes

public List<IAttribute<?>> getAttributes()

Specified by:

getAttributes in interface IType<T>

getAccessorKeys

public Map<IAccessorKey<?>,? extends IDescribable> getAccessorKeys()

Description copied from interface: IType

Get keys for the accessors that this type knows of. Note that the returned accessors does not necessarily cover all possible data from the items of this type, and that it is always possible to define additional accessors that get or calculate values from the items in non-standard ways.

Should only be used for low level type inspection. Iterators etc. should use a collection of predefined attributes.

Specified by:

getAccessorKeys in interface IType<T>

Returns:

keys for the accessors defined for this type

hasAttribute

public boolean hasAttribute(ICanonicalAccessorFactory<?> attribute)

Description copied from interface: IType

Tell if attribute can return an accessor for this type. This method is semantically equivalent to attribute.getAccessor(type) != null, but may be cheaper.

Specified by:

hasAttribute in interface IType<T>

Parameters:

attribute - attribute to check

Returns:

true if the attribute can return an accessor for this type, false if not

getAccessor

public <M> IMemberAccessor<M,T> getAccessor(IAccessorKey<M> attribute)

Description copied from interface: IType

Internal low-level mechanism for retrieving a member accessor for a type, or null if not available.

This is only intended to be used by implementors of IAccessorFactory. All other usage should be replaced with ICanonicalAccessorFactory.getAccessor(IType) call to pre-defined accessors.

Specified by:

getAccessor in interface IType<T>

Type Parameters:

M - accessor value type

Parameters:

attribute - the identifier for the field

Returns:

a member accessor

toString

public String toString()

Overrides:

toString in class Object

lookupNameFor

protected static String lookupNameFor(String typeIdentifier)
