Method Detail

makeSnapshot

public static OccurrenceIF makeSnapshot(OccurrenceIF original,
                                        int snapshotType,
                                        Map<TMObjectIF,SnapshotTMObject> processed)

getTopic

public TopicIF getTopic()

Description copied from interface: OccurrenceIF

PUBLIC: Gets the topic for this occurrence.

Specified by:

getTopic in interface OccurrenceIF

Returns:

The topic to which this occurrence belongs; an object implementing TopicIF.

getDataType

public LocatorIF getDataType()

Description copied from interface: OccurrenceIF

PUBLIC: Gets the data type of this occurrence.

Specified by:

getDataType in interface OccurrenceIF

getValue

public String getValue()

Description copied from interface: OccurrenceIF

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

Specified by:

getValue in interface OccurrenceIF

setValue

public void setValue(String value,
                     LocatorIF datatype)

Description copied from interface: OccurrenceIF

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

Specified by:

setValue in interface OccurrenceIF

getReader

public Reader getReader()

Description copied from interface: OccurrenceIF

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

Specified by:

getReader in interface OccurrenceIF

setReader

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

Description copied from interface: OccurrenceIF

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

Specified by:

setReader in interface OccurrenceIF

setLocator

public void setLocator(LocatorIF locator)

Description copied from interface: OccurrenceIF

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

Specified by:

setLocator in interface OccurrenceIF

getLength

public long getLength()

Description copied from interface: OccurrenceIF

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

Specified by:

getLength in interface OccurrenceIF

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)

Parameters:

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

removeTheme

public void removeTheme(TopicIF theme)
