Method Detail

detach

public void detach()

Specified by:

detach in interface PersistentIF

Specified by:

detach in class AbstractRWPersistent

_p_getFieldCount

public int _p_getFieldCount()

Specified by:

_p_getFieldCount in interface PersistentIF

getClassIndicator

public java.lang.String getClassIndicator()

Description copied from class: TMObject

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

Specified by:

getClassIndicator in class TMObject

getObjectId

public java.lang.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 TMObject

Returns:

string which is this object's id.

remove

public void remove()

Description copied from interface: TMObjectIF

PUBLIC: Removes the object from its parent.

Specified by:

remove in interface TMObjectIF

getTopic

public TopicIF getTopic()

Description copied from interface: VariantNameIF

PUBLIC: Gets the topic to which this variant name belongs.

Specified by:

getTopic in interface VariantNameIF

Returns:

The topic named by this variant 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

protected void setDataType(LocatorIF datatype)

getValue

public java.lang.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 VariantNameIF

setValue

public void setValue(java.lang.String value)

Description copied from interface: VariantNameIF

PUBLIC: Same as setValue(value, DataTypes.TYPE_STRING). This method is here primarily for backwards compatibility.

Specified by:

setValue in interface VariantNameIF

setValue

public void setValue(java.lang.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 java.io.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(java.io.Reader value,
                      long length,
                      LocatorIF datatype)

Specified by:

setReader in interface VariantNameIF

getLocator

public LocatorIF getLocator()

Description copied from interface: VariantNameIF

PUBLIC: Returns a LocatorIF representation of the variant value. This method will return null if the value is not of type xsd:anyURI (same as DataType.TYPE_URI). This method is here primarily for backwards compatibility.

Specified by:

getLocator 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:
