public abstract class AbstractReadHandlerFactory<T extends XmlReadHandler> extends Object
The AbstractReadHandlerFactory provides a base implementation for all read-handler factories. A read-handler factory decouples the tag-handlers of a SAX parser and allows to configure alternate parser configuations at runtime, resulting in a more flexible parsing process.- Author:

Method Detail
-
configureGlobal
public void configureGlobal(org.pentaho.reporting.libraries.base.config.Configuration config, String prefix)
-
configure
public void configure(org.pentaho.reporting.libraries.base.config.Configuration conf, String prefix)
Configures this factory from the given configuration using the specified prefix as filter.- Parameters:
conf
- the configuration.prefix
- the key-prefix.
-
setNamespaceHandler
public void setNamespaceHandler(String namespaceUri, Class<? extends T> hasCData)
Adds a configuration default for the given namespace to the tag-descriptions. If the namespace URI given here is null, this defines the global default for all namespaces.- Parameters:
namespaceUri
- the namespace URI for which a default should be configured.hasCData
- the default value.
-
setElementHandler
public void setElementHandler(String namespaceUri, String tagName, Class<? extends T> hasCData)
Adds a configuration entry for the given namespace and tag-name to the tag-descriptions.- Parameters:
namespaceUri
- the namespace URI for which a default should be configured.tagName
- the tagname for which the entry should be added.hasCData
- the default value.
-
setElementHandler
public void setElementHandler(String tagName, Class<? extends T> hasCData)
Adds a configuration entry for the given namespace and tag-name to the tag-descriptions.- Parameters:
tagName
- the tagname for which the entry should be added.hasCData
- the default value.
-
setDefaultNamespace
public void setDefaultNamespace(String defaultNamespace)
-
getDefaultNamespace
public String getDefaultNamespace()
-
getTargetClass
protected abstract Class<T> getTargetClass()
Returns the implementation class for this read-handler factory.- Returns:
- the implementation class.
-
getHandler
public T getHandler(String namespace, String tagname)
The returned handler can be null, in case no handler is registered.- Parameters:
namespace
- the namespace of the xml-tag for which a handler should be returned.tagname
- the tagname of the xml-tag.- Returns:
- the instantiated read handler, or null if there is no handler registered.
