org.apache.tools.ant.taskdefs.optional.ejb.DescriptorHandler
| DescriptorHandler | | public class DescriptorHandler extends org.xml.sax.HandlerBase (Code) | | Inner class used by EjbJar to facilitate the parsing of deployment
descriptors and the capture of appropriate information. Extends
HandlerBase so it only implements the methods needed. During parsing
creates a hashtable consisting of entries mapping the name it should be
inserted into an EJB jar as to a File representing the file on disk. This
list can then be accessed through the getFiles() method.
|
| Field Summary | |
| protected String | currentElement
Instance variable used to store the name of the current element being
processed by the SAX parser. | | protected String | currentText
| | protected Hashtable | ejbFiles
Instance variable that stores the names of the files as they will be
put into the jar file, mapped to File objects Accessed by the SAX
parser call-back method characters(). | | protected String | ejbName
|
| Method Summary | |
| public void | characters(char[] ch, int start, int length)
SAX parser call-back method invoked whenever characters are located within
an element. | | public void | endElement(String name)
SAX parser call-back method that is invoked when an element is exited.
Used to blank out (set to the empty string, not nullify) the name of
the currentAttribute. | | public String | getEjbName()
Getter method that returns the value of the <ejb-name> element. | | public Hashtable | getFiles()
Getter method that returns the set of files to include in the EJB jar. | | public String | getPublicId()
| | protected void | processElement()
Called when an endelement is seen. | | public void | registerDTD(String publicId, String location)
Register a dtd with a location. | | public InputSource | resolveEntity(String publicId, String systemId)
Resolve the entity.
See Also: org.xml.sax.EntityResolver#resolveEntity(String, String).
Parameters:
publicId - The public identifier, or nullif none is available.
Parameters:
systemId - The system identifier provided in the XMLdocument. | | public void | startDocument()
SAX parser call-back method that is used to initialize the values of some
instance variables to ensure safe operation. | | public void | startElement(String name, AttributeList attrs)
SAX parser call-back method that is invoked when a new element is entered
into. |
| currentElement | | protected String currentElement(Code) | | Instance variable used to store the name of the current element being
processed by the SAX parser. Accessed by the SAX parser call-back methods
startElement() and endElement().
|
| currentText | | protected String currentText(Code) | | The text of the current element
|
| ejbFiles | | protected Hashtable ejbFiles(Code) | | Instance variable that stores the names of the files as they will be
put into the jar file, mapped to File objects Accessed by the SAX
parser call-back method characters().
|
| ejbName | | protected String ejbName(Code) | | Instance variable that stores the value found in the <ejb-name> element
|
| DescriptorHandler | | public DescriptorHandler(Task task, File srcDir)(Code) | | Constructor for DescriptorHandler.
Parameters:
task - the task that owns this desciptor
Parameters:
srcDir - the source directory |
| characters | | public void characters(char[] ch, int start, int length) throws SAXException(Code) | | SAX parser call-back method invoked whenever characters are located within
an element. currentAttribute (modified by startElement and endElement)
tells us whether we are in an interesting element (one of the up to four
classes of an EJB). If so then converts the classname from the format
org.apache.tools.ant.Parser to the convention for storing such a class,
org/apache/tools/ant/Parser.class. This is then resolved into a file
object under the srcdir which is stored in a Hashtable.
Parameters:
ch - A character array containing all the characters inthe element, and maybe others that should be ignored.
Parameters:
start - An integer marking the position in the chararray to start reading from.
Parameters:
length - An integer representing an offset into thechar array where the current data terminates.
throws:
SAXException - on error |
| endElement | | public void endElement(String name) throws SAXException(Code) | | SAX parser call-back method that is invoked when an element is exited.
Used to blank out (set to the empty string, not nullify) the name of
the currentAttribute. A better method would be to use a stack as an
instance variable, however since we are only interested in leaf-node
data this is a simpler and workable solution.
Parameters:
name - The name of the attribute being exited. Ignoredin this implementation.
throws:
SAXException - on error |
| getEjbName | | public String getEjbName()(Code) | | Getter method that returns the value of the <ejb-name> element.
the ejb name |
| getFiles | | public Hashtable getFiles()(Code) | | Getter method that returns the set of files to include in the EJB jar.
the map of files |
| getPublicId | | public String getPublicId()(Code) | | Get the publicId of the DTD
the public id |
| processElement | | protected void processElement()(Code) | | Called when an endelement is seen.
This may be overridden in derived classes.
This updates the ejbfiles if the element is an interface or a bean class.
This updates the ejbname if the element is an ejb name.
|
| registerDTD | | public void registerDTD(String publicId, String location)(Code) | | Register a dtd with a location.
The location is one of a filename, a resource name in the classpath, or
a URL.
Parameters:
publicId - the public identity of the dtd
Parameters:
location - the location of the dtd |
| resolveEntity | | public InputSource resolveEntity(String publicId, String systemId) throws SAXException(Code) | | Resolve the entity.
See Also: org.xml.sax.EntityResolver#resolveEntity(String, String).
Parameters:
publicId - The public identifier, or nullif none is available.
Parameters:
systemId - The system identifier provided in the XMLdocument. Will not be null. an inputsource for this identifier
throws:
SAXException - if there is a problem. |
| startDocument | | public void startDocument() throws SAXException(Code) | | SAX parser call-back method that is used to initialize the values of some
instance variables to ensure safe operation.
throws:
SAXException - on error |
| startElement | | public void startElement(String name, AttributeList attrs) throws SAXException(Code) | | SAX parser call-back method that is invoked when a new element is entered
into. Used to store the context (attribute name) in the currentAttribute
instance variable.
Parameters:
name - The name of the element being entered.
Parameters:
attrs - Attributes associated to the element.
throws:
SAXException - on error |
