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

Age	The set- and get- processors implemented in this file can be used to make a virtual 'age' field.
Age.Getter
Age.Setter
BinaryCommitProcessor	Used as 'commitprocessor' on the 'binaries'.
BinaryFile	This class constains Setter and Getter method for 'binary' file fields.
BinaryFile.Delete
BinaryFile.Getter
BinaryFile.Setter
BinaryFile.StringGetter	A bit of a hack, used if the file was originally saved in a transaction, and hence has a negative number prefix.
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 produce a CharTransformer), to be a ParameterizedProcessorFactory.
ChecksumGetProcessorFactory	See ChecksumFactory.
ChecksumProcessorFactory	See ChecksumFactory.
ContextProcessor
ContextProcessor.Get
ContextProcessor.Set
Cookies	Setter and Getter to make a virtual field which stores the actual value in a user's cookie.
Cookies.CookieBase
Cookies.Getter
Cookies.Setter
CopyFieldCommitProcessorFactory	This factory produces commit-processors which simply copies the value of another field of the same node, to the field with which this CommitProcessor was associated.
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.
DefaultOwner
DelayedGetter	To be used in conjuction with DelayedSetter.
DelayedSetter	If you use a DelaySetter on a field, than the process of the field will make sure that the field is not actually changed (the original value is returned).
DelayedSetter.NodeField
DelayedSetter.SetThread
Duration	Formats a long with hour:minutes:seconds.
Duration.DataType
Duration.GetString
Duration.SetString
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.
FormatFileSize.Parser
FormatQuantity	A processor that gets a number as a file-size, that is, rounded with kbytes and Mb's and so on.
FormatQuantity.Parser
FunctionValueIfEmptyCommitProcessor	If this commit-processor is configured on a field, then on commit of the node, the value of a certain function (on the same node), is set into the field, if the field is empty.
FunctionValueIfEmptyGetter	This processor can be used on a field to return a certain function value of the node, if the field is empty.
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, then you can effectively set the value only once (until the commit of the node).
Ip	This processor can be used as a 'commit' processor on a string field.
KeywordsProcessor	This processor can be used as a 'set' processor on keyword fields.
KeywordsProcessor.EntryComparator
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)
ObjectTypeChangerCommitProcessor	It also implements simply copying the value of another field in such cases (using the 'fieldName') parameter.
ObjectTypeChangerCommitProcessor.Getter
OriginTrace
OtherField	The set- and get- processors implemented in this file can be used to make a virtual field which acts as another field of the same node
OtherField.AbstractProcessor
OtherField.Getter
OtherField.Setter
PathRelatedList
PathRelatedList.AbstractProcessor
PathRelatedList.Getter
PosrelCommitProcessor	Used as 'commitprocessor' on the 'pos' field of a posrel object, this guesses a nice default if you left the value empty on commit.
Readonly	This processor can be used as a 'set' processor on a field.
Related	The set- and get- processors implemented in this file can be used to make a virtual field which act as a a node field, but actually is a related node.
Related.AbstractProcessor
Related.Creator	This get-processor can be used to implicitly create the wanted related node too.
Related.Getter
Related.Setter
RelatedField	The set- and get- processors implemented in this file can be used to make a virtual field which acts as a field of a related node.
RelatedField.AbstractProcessor
RelatedField.Creator
RelatedField.Getter
RelatedField.Setter
RelatedList	The set- and get- processors implemented in this file can be used to make a virtual field which act as a list (or 'set') field, but actually represents related nodes.
RelatedList.AbstractProcessor
RelatedList.Getter
RelatedList.Setter

Package org.mmbase.datatypes.processors Description

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

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.

Processors can be parameterized in two ways. Using a ParameterizedProcessorFactory or ParameterizedCommitProcessorFactory or simply by using bean-like setting on the instance. Both ways are recognized in builder xml's.

Since:

MMBase-1.7
