Class DescriptorParser

java.lang.Object

org.xml.sax.helpers.DefaultHandler

org.apache.hivemind.parse.AbstractParser

org.apache.hivemind.parse.DescriptorParser

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public final class DescriptorParser

Field Detail

ID_PATTERN

public static final java.lang.String ID_PATTERN

Format for configuration point ids, service point ids and schema ids. Consists of an optional leading underscore, followed by alphanumerics and underscores. Normal naming convention is to use a single CamelCase word, like a Java class name.

Method Detail

begin

public void begin(java.lang.String elementName,
         java.util.Map attributes)

Description copied from class: AbstractParser

Invoked when an element's start tag is recognized. The element and attributes are provided to the subclass for further processing.

Specified by:

begin in class AbstractParser

push

protected void push(java.lang.String elementName,
        java.lang.Object object,
        int state)

Description copied from class: AbstractParser

Enters a new state, pushing an object onto the stack. Invokes AbstractParser.push(String, Object, int, boolean), and ignores character data within the element.

Overrides:

push in class AbstractParser

Parameters:

elementName - the element whose start tag was just parsed

object - the object created to represent the new object

state - the new state for the parse

end

public void end(java.lang.String elementName)

Description copied from class: AbstractParser

Invoked when an element's close tag is recognized. The element is provided. The content of the element (the unparsed whitespace within the element's tags) is available via AbstractParser.peekContent().

Specified by:

end in class AbstractParser

public void initialize(Resource resource,
              ClassResolver resolver)
