setAttribute

public void setAttribute(java.lang.String pQName,
                         java.lang.String pNamespaceURI,
                         java.lang.String pLocalName,
                         java.lang.String pValue)
                  throws org.xml.sax.SAXException

This method configures the bean pBean as follows:

1. If the bean has a method setAttribute(String, String, String), it is invoked with the following arguments:
   • The attributes namespace URI (empty string for the default namespace),
   • the attributes local name,
   • and the property value
2. Otherwise invokes its own method setProperty(Object, String, String, String).

Specified by:

setAttribute in interface AttributeSetter

Throws:

org.xml.sax.SAXException

invokeMethod

protected java.lang.Object invokeMethod(java.lang.Object pBean,
                                        java.lang.reflect.Method pMethod,
                                        java.lang.String pName,
                                        java.lang.Object[] pArgs)
                                 throws org.xml.sax.SAXException

This method invokes the beans pBean method pMethod, setting the attribute pName to the value pArgs.

Throws:

org.xml.sax.SAXException

setProperty

protected boolean setProperty(java.lang.Object pBean,
                              java.lang.String pQName,
                              java.lang.String pName,
                              java.lang.String pValue)
                       throws org.xml.sax.SAXException

This method is invoked from within setAttribute(String, String, String, String). It configures the bean pBean as follows;

1. If the bean has a method setProperty(String) this method is invoked with the attribute value.
2. If the bean has a method setProperty(T), and the class T has either of a method public static T valueOf(String) or a constructor public T(String) (in that order), then the method setProperty(T) is invoked with the value obtained by an invocation of the method valueOf(), or the constructor, respectively. Note, that this applies in particular to the classes Long, Integer, Short, Byte, Double, Float, java.math.BigInteger, java.math.BigDecimal, File, and StringBuffer.
3. If the bean has a method setProperty(boolean), the method will be invoked with the value true (the value specified in the XML file is either of true, or 1, otherwise with the value false.
4. If the bean has a method setProperty(char), or setProperty(Character), the method will be invoked with the first character of the value specified in the XML file. If the value contains zero or multiple characters, an IllegalArgumentException is thrown.
5. If the bean has either of the following methods, in that order:
   • setProperty(long)
   • setProperty(int)
   • setProperty(short)
   • setProperty(byte)
   • setProperty(double)
   • setProperty(float)
   then the property value is converted into the respective type and the method is invoked. An IllegalArgumentException is thrown, if the conversion fails.
6. If the bean has a method java.lang.Class, the XsSAXParser will interpret the value given in the XML file as a Java class name and load the named class from its class loader. If the class cannot be loaded, it will also try to use the current threads context class loader. An exception is thrown, if neither of the class loaders can load the class.

Returns:

True, if a method for setting the property was found. Otherwise false.

Throws:

org.xml.sax.SAXException
