Constructor Detail

ReadOnlyVariantName

public ReadOnlyVariantName()

Method Detail

_p_getFieldCount

public int _p_getFieldCount()

Specified by:

_p_getFieldCount in interface PersistentIF

getClassIndicator

public String getClassIndicator()

Description copied from class: ReadOnlyTMObject

INTERNAL: Returns the token that can be used to indicate the class of this instance. This indicator is currently only used by item identifiers.

Specified by:

getClassIndicator in class ReadOnlyTMObject

getObjectId

public String getObjectId()

Description copied from interface: TMObjectIF

PUBLIC: Gets the id of this object. The object id is part of the topic map id space, and must be unique. The object id is not significant (or unique) outside the current topic map. The object id is immutable. The object id is thus stable through this object's lifetime.

Specified by:

getObjectId in interface TMObjectIF

Specified by:

getObjectId in class ReadOnlyTMObject

Returns:

string which is this object's id.

getTopic

public TopicIF getTopic()

Description copied from interface: NameIF

PUBLIC: Gets the topic to which this name belongs.

Specified by:

getTopic in interface NameIF

Returns:

The topic named by this name; an object implementing TopicIF.

getTopicName

public TopicNameIF getTopicName()

Description copied from interface: VariantNameIF

PUBLIC: Gets the topic name to which this variant name belongs. The topic name may be a direct parent or an ancestor.

Specified by:

getTopicName in interface VariantNameIF

Returns:

The topic name of which this is a variant; an object implementing TopicNameIF.

getDataType

public LocatorIF getDataType()

Description copied from interface: VariantNameIF

PUBLIC: Gets the data type of this variant.

Specified by:

getDataType in interface VariantNameIF

setDataType

public void setDataType(LocatorIF datatype)

getValue

public String getValue()

Description copied from interface: VariantNameIF

PUBLIC: Gets the string representation of this variant. This method will return null if the length of the value exceeds the supported maximum size.

Specified by:

getValue in interface NameIF

Specified by:

getValue in interface VariantNameIF

Returns:

A string which is the value of this topic name.

setValue

public void setValue(String value,
                     LocatorIF datatype)

Description copied from interface: VariantNameIF

PUBLIC: Sets the value and the data type of this variant using a string. The value must conform to the correct string representation according to the datatype.

Specified by:

setValue in interface VariantNameIF

getReader

public Reader getReader()

Description copied from interface: VariantNameIF

PUBLIC: Returns a Reader that allows you to stream the string representation of this variant. Values of all sizes are supported by this method.

Specified by:

getReader in interface VariantNameIF

setReader

public void setReader(Reader value,
                      long length,
                      LocatorIF datatype)

Description copied from interface: VariantNameIF

PUBLIC: Sets the value and the data type of this variant using a reader. The reader value must conform to the correct string representation according to the datatype.

Specified by:

setReader in interface VariantNameIF

setLocator

public void setLocator(LocatorIF locator)

Description copied from interface: VariantNameIF

PUBLIC: Same as setValue(locator.getAddress(), DataTypes.TYPE_URI). This method is here primarily for backwards compatibility.

Specified by:

setLocator in interface VariantNameIF

getLength

public long getLength()

Description copied from interface: VariantNameIF

PUBLIC: Returns the length of the variant value. The number of characters in the string representation is returned.

Specified by:

getLength in interface VariantNameIF

getScope

public Collection<TopicIF> getScope()

Description copied from interface: ScopedIF

PUBLIC: Returns the set of topics that are the stated scope of this object. Scoping topics inherited from parent objects are not included. There is no guarantee as to which order these topics are returned in.

Specified by:

getScope in interface ScopedIF

Returns:

A collection of TopicIF objects.

addTheme

public void addTheme(TopicIF theme)

Description copied from interface: ScopedIF

PUBLIC: Add a topic to this scope. (A topic used in a scope is also called a theme.) If the topic is already part of the scope the method call has no effect.

Specified by:

addTheme in interface ScopedIF

Parameters:

theme - A topic to be added to this scope; an object implementing TopicIF.

removeTheme

public void removeTheme(TopicIF theme)

Description copied from interface: ScopedIF

PUBLIC: Remove a topic from this scope. If the topic is not already in the scope this method has no effect. (A topic used in a scope is also called a theme.)

Specified by:

removeTheme in interface ScopedIF

Parameters:

theme - A topic to be removed from this scope; an object implementing TopicIF.

getReifier

public TopicIF getReifier()

Description copied from interface: ReifiableIF

Specified by:

getReifier in interface ReifiableIF

setReifier

public void setReifier(TopicIF reifier)

Description copied from interface: ReifiableIF

PUBLIC: Sets the reifier of this object.

Specified by:

setReifier in interface ReifiableIF

toString

public String toString()

Overrides:

toString in class Object
