Description

Interface Summary

CommitProcessor	If the processor defined for the field is of this type, then the CommitProcessor.commit(org.mmbase.bridge.Node, org.mmbase.bridge.Field) method will be called on commit of the Node.
ParameterizedCommitProcessorFactory	A parameterized commitprocessor factory creates CommitProcessors, using Parameters.
ParameterizedProcessorFactory	A parameterized commitprocessor factory creates Processors, using Parameters.
Processor	Interface for doing field processing.

Class Summary

ChainedCommitProcessor	Chains a bunch of other processors into one new processor.
ChainedProcessor	Chains a bunch of other processors into one new processor.
CharTransformerProcessor	A processor based on a chartransformer (works only for Strings).
CharTransformerProcessorFactory	Wraps a ParameterizedTransformerFactory (it must produces CharTransformer), to be a ParameterizedProcessorFactory.
ChecksumProcessorFactory	See ChecksumFactory.
CopyProcessor	The Processor that does nothing.
CreationTimeGuesser	Get-processor for 'created' field.
Creator	This processor can be used as a 'set' processor on a (datetime) field.
EmptyCommitProcessor	The CommitProcessor that does nothing.
FileNameProcessor	Some browers provide directory information (IE on Windows), and FileItem.getName() still includes that.
FormatDateTime	This can be used as getProcessor for String on DateTime fields.
FormatFileSize	A processor that gets a number as a file-size, that is, rounded with kbytes and Mb's and so on.
IgnoreEmptyProcessor	If you use this processor for a field, then setting it to an empty value will be ignored (the previous value will remain intact).
IgnoreIfChangedProcessor	If this processor is used on a certain field, that you can effectively set the value only once (until the commit of the node).
LastModified	This processor can be used as a 'commit' processor on a (datetime) field.
LastModifiedProcessorFactory	This factory creates processors which don't actually change the value, but only have a side-effect, namely updating another field with the current time.
LastModifier	This processor can be used as a 'commit' processor on a string field.
NodeNumber	If value is a node, returns it's number (as a String)
Readonly	This processor can be used as a 'set' processor on a field.

Package org.mmbase.datatypes.processors Description

Plugins into set- and getValue methods on Node (Setting and getting Fields).

In this directory the framework for putting functionality there is implemented. The basic agent is 'ValueIntercepter' which reads an XML and provides the set- and get-Value implemntation with the specified 'Processor'.

When functionality is added to a certain field type then a Processor must be implemented and turned on in datatypes.xml or the builder xml.

Since:

MMBase-1.7
