public class TemplatesPool

extends java.util.Hashtable

"Set"-like container for Templates instanced. This class extends standard Hashtable for storing (ID, Template) pairs. However, the storage is implemented in following manner: the pairs should be added to the pool using the add() methods - when in pool already exists a Templates object associated with specified ID, this object is returned by the add() method (i. e. no new Template object is created);. If it is required to reassign a Template object to given ID in the pool, either methods remove()() followed by add() method should be used, or you can use the Hashtable put() method.

public javax.xml.transform.Templates add(java.lang.String ID,
                                         javax.xml.transform.Templates t)
                                  throws ParseException

Adds new Templates - the pool, with ID as the key.

Throws:

ParseException

get

public javax.xml.transform.Templates get(java.lang.String ID)

Returns Template with given ID from the pool.

Returns:

null if no Template associated with given ID exists in pool.

remove

public javax.xml.transform.Templates remove(java.lang.String ID)

Returns:

the Template object with specified ID, which was removed from the pool, or null, if no such Template existed.

clear

public void clear()

Removes all objects from the pool.

containsURI

public boolean containsURI(java.lang.String URI)

Checks, if any Templates based on the file with String URI parameter is in the pool.
