Interface MetamergeConfig

All Superinterfaces:

BaseConfiguration, MetamergeFolder, Serializable

All Known Implementing Classes:

MetamergeConfigFS, MetamergeConfigImpl, MetamergeConfigXML

public interface MetamergeConfig
extends MetamergeFolder

The MetamergeConfig interface specifies the methods used by metamerge to obtain configuration information. The configuration interface is a hierarchical tree of objects and each object's unique name is composed of a number of strings separated by a slash (see MetamergeConfigFactory). If the implementor chooses another naming schema it should perform a name mapping between the slash separated naming and its own local naming schema. Instantiation of a MetamergeConfig object should always performed by the MetamergeConfigFactory. The latter builds a hastable of parameters which is passed to the implementation of this interface.

Returns an enumeration of the immediate children of this node

Parameters:

name - The folder name to list

Returns:

Enumeration object of javax.naming.Binding objects with names and objects

Throws:

Exception

lookup

Object lookup(Object name)
              throws Exception

Searches this configuration for a named node.

Parameters:

name - The name to lookup

Returns:

The configuration object found

Throws:

Exception

unbind

void unbind(Object name)
            throws Exception

Removes a named object from this configuration.

Parameters:

name - The object name to remove

Throws:

Exception

bind

void bind(Object name,
          Object obj)
          throws Exception

Adds a new object to the configuration at the location specified by name

Parameters:

name - Name

obj - Configuration Object

Throws:

Exception

rebind

void rebind(Object name,
            Object obj)
            throws Exception

Adds or replaces a new object to the configuration.

Parameters:

name - Name

obj - Configuration Object

Throws:

Exception

rename

void rename(Object name,
            Object newName)
            throws Exception

Renames an object. If new name is a simple name then location is unchanged, otherwise the object is moved.

Parameters:

name - Current Name

newName - New name

Throws:

Exception

commitChanges

void commitChanges(Object output,
                   boolean isSave)
                   throws Exception

Tells the configuration driver to save all modified objects. Not all config drivers support this method. Typically drivers that work with streams (e.g. files) will implement this method to flush its cache to disk. The output parameter may be any object understood by the driver and serves as a temporary output destination. Use the setOutput() to permanently change the output URL for the driver.

Parameters:

output - Null or any object supported by the underlying driver.

isSave - true if this is a permanent save, false if this just saves to e.g. a command window.

Throws:

Exception

commitChanges

void commitChanges(Object output)
                   throws Exception

Tells the configuration driver to save all modified objects. This has the same effect as commitChanges( output, true)

Parameters:

output - Null or any object supported by the underlying driver.

Throws:

Exception

isCommittable

boolean isCommittable()

Returns true if the configuration driver implements the commitChanges method and the current value for PROVIDER_URL is writable.

Returns:

The committable state

isReadOnly

boolean isReadOnly()

Returns true if this configuration cannot be modified.

Returns:

The readOnly value

setOutput

void setOutput(Object output)
               throws Exception

Changes the output to wich the configuration driver writes its configuration. This is different from calling commitChanges(output, false) where the output parameter is temporary (e.g. SaveCopyAs).

Parameters:

output - The new output value

Throws:

Exception

initializeConfig

void initializeConfig()
                      throws Exception

Initialize the driver

Throws:

Exception

closeConfig

void closeConfig()
                 throws Exception

Close the driver

Throws:

Exception

copy

void copy(BaseConfiguration input,
          Object destination,
          boolean copyRefs)
          throws Exception

Copies a configuration object into this configuration. This differs from the bind/rebind method in that all copied objects are stored in a different branch than the original objects. Also, the copied objects' referenced objects may be copied in as well.

Parameters:

input - Configuration object to be copied

destination - The name of the destination object (javax.naming.Name or String)

copyRefs - If true, copy referenced objects as well (e.g. all inherited objects)

Throws:

Exception

                                               throws Exception

Returns the ExternalPropertiesConfig object for the named external properties object. Name can either be a simple name or a fully qualified name. For simple names, the config driver will lookup the object in the default folder for external properties.

Parameters:

Returns:

The ExternalPropertiesConfig object

Throws:

Exception

addNameComponent

Object addNameComponent(Object name,
                        String component,

                        throws Exception

Adds a name component to the NameComponent attribute of the MetamergeConfig object

Parameters:

prefix - If true, component is inserted at beginning of name

Returns:

The provided name or a new instance of javax.naming.Name
