Method Detail

getId

public String getId()

Description copied from interface: TopicMapSourceIF

PUBLIC: Gets the id of the source.

Specified by:

getId in interface TopicMapSourceIF

setId

public void setId(String id)

Description copied from interface: TopicMapSourceIF

PUBLIC: Sets the id of the source. Note that this method is intended for use when the source is used in a TopicMapRepositoryIF. The source should throw an UnsupportedOperationException if it does not support setting the id.

Specified by:

setId in interface TopicMapSourceIF

getReferenceId

public String getReferenceId()

INTERNAL: Gets the id of the topic map reference for this topic map source.

setReferenceId

public void setReferenceId(String refid)

INTERNAL: Sets the id of the topic map reference for this topic map source.

getTitle

public String getTitle()

Description copied from interface: TopicMapSourceIF

PUBLIC: Gets the title of the source.

Specified by:

getTitle in interface TopicMapSourceIF

setTitle

public void setTitle(String title)

Description copied from interface: TopicMapSourceIF

PUBLIC: Sets the title of the source.

Specified by:

setTitle in interface TopicMapSourceIF

getSyntax

public String getSyntax()

INTERNAL: Returns the syntax of the document.

setSyntax

public void setSyntax(String syntax)

INTERNAL: Specifies the syntax of the document. This property will be used to ensure that the topic map syntax is correctly recognized. The supported syntaxes are 'XTM', 'HyTM', and 'LTM'. If the syntax is not specified the class will attempt to guess it by looking at the address suffix.

getUrl

public String getUrl()

INTERNAL: Gets the URL of the source topic map.

setUrl

public void setUrl(String url)

INTERNAL: Sets the URL of the source topic map.

getBase

public LocatorIF getBase()

INTERNAL: Gets the base locator of the topic maps retrieved from the source.

setBase

public void setBase(LocatorIF base_address)

INTERNAL: Sets the base locator of the topic maps retrieved from the source.

getBaseAddress

public String getBaseAddress()

INTERNAL: Gets the base address of the topic maps retrieved from the source. The notation is assumed to be 'URI'.

setBaseAddress

public void setBaseAddress(String base_address)

INTERNAL: Sets the base address of the topic maps retrieved from the source. The notation is assumed to be 'URI'.

getDuplicateSuppression

public boolean getDuplicateSuppression()

INTERNAL: Gets the duplicate suppression flag. If the flag is true duplicate suppression is to be performed when loading the topic maps.

setDuplicateSuppression

public void setDuplicateSuppression(boolean duplicate_suppression)

INTERNAL: Sets the duplicate suppression flag. If the flag is true duplicate suppression is to be performed when loading the topic maps.

setValidation

public void setValidation(boolean validate)

INTERNAL: Turn validation of XTM documents according to DTD on or off. The validation checks if the documents read follow the DTD, and will abort import if they do not.

Parameters:
