Class ConcurrentMerge

java.lang.Object

com.deltaxml.merge.ConcurrentMerge

All Implemented Interfaces:

MergeBase, MergeCommon

public class ConcurrentMerge
extends Object
implements MergeCommon

A merge class which supports n-way merging of the concurrently edited XML content (data or documents) .

The term concurrent describes a scenario in which the ancestor version is known to be the original version from which the other versions are derived and therefore precedes them in time. The other versions that are merged are treated symmetrically as if they had no temporal or other relationship (such a derivation) between each other. To perform a merge where each of the versions added to the merge is a derivative of the previous version use SequentialMerge.

An alternative class ThreeWayMerge is provided with similar capabilities for the common three way use case, but which also provides a number of additional output types/formats.

Since:

4.0

Constructor Details

ConcurrentMerge

public ConcurrentMerge()

Constructs a new ConcurrentMerge instance.

Default settings

After construction the ConcurrentMerge object will, by default, preserve Doctype information. The DoctypePreservationMode.PRESERVE_WHEN_UNCHANGED setting is used unless configured with the setDoctypePreservationMode(com.deltaxml.mergecommon.config.DoctypePreservationMode) method.

Also, entity references will be preserved by default. The EntityReferencePreservationMode.PRESERVE_REFERENCES setting is used unless configured with the setEntityReferencePreservationMode(com.deltaxml.mergecommon.config.EntityReferencePreservationMode) method.

Method Details

getFilterStepHelper

public FilterStepHelper getFilterStepHelper()

Returns the Filter Step helper.

This can be used to create filters used to extend the Merger via its extension points.

Returns:

the FilterStephelper associated with the Merger

setResultType

public void setResultType(ConcurrentMergeResultType type)

Sets the type of result which this Merger will produce.

Parameters:

type - the desired result type

getResultType

public ConcurrentMergeResultType getResultType()

Reports the result type setting for the Merger.

Returns:

the current result type setting

setExtensionPoint

public void setExtensionPoint(ExtensionPoint extensionPoint,
 FilterChain chain)

Sets the FilterChain to run at the specified ExtensionPoint.

N.B. the supplied FilterChain will have its name set to the name of the supplied ExtensionPoint parameter (i.e. the result of calling ExtensionPoint.toString() ).

Parameters:

extensionPoint - the ExtensionPoint at which to insert the FilterChain;

chain - the FilterChain containing the FilterSteps to insert at the specified extension point

setDebugFiles

public void setDebugFiles(boolean debug)

Enables the generation of intermediate pipeline debug files.

Specified by:

setDebugFiles in interface MergeBase

Parameters:

debug - when true debug files are generated

getDebugFiles

public boolean getDebugFiles()

Gets whether the production of debug files is on or not.

Specified by:

getDebugFiles in interface MergeBase

Returns:

whether the production of debug files is on or not.

See Also:

• MergeBase.setDebugFilesPrefix(String)

setDebugFilesPrefix

public void setDebugFilesPrefix(String prefix)

Provides a prefix for debug result files.

Specified by:

setDebugFilesPrefix in interface MergeBase

Parameters:

prefix - The prefix that will be used for debug file names in subsequent merge operations

See Also:

• MergeBase.setDebugFiles(boolean)

getDebugFilesPrefix

public String getDebugFilesPrefix()

Get the current prefix used for debug result files.

Specified by:

getDebugFilesPrefix in interface MergeBase

Returns:

the current prefix used for debug result files.

See Also:

• MergeBase.setDebugFiles(boolean)

setIndent

public void setIndent(boolean indent)

Enables indentation of output using the serializer output indent property.

Specified by:

setIndent in interface MergeBase

Parameters:

indent - when true the output is indented

getEntityResolver

public EntityResolver getEntityResolver()

Gets the explicitly set EntityResolver in use by the merger.

Specified by:

getEntityResolver in interface MergeBase

Returns:

the explicitly set EntityResolver in use by the merger.

getEntityResolver

public EntityResolver getEntityResolver(boolean builtInResolver)

Gets the EntityResolver in use by the merger.

Specified by:

getEntityResolver in interface MergeBase

Parameters:

builtInResolver - Whether to get the built in resolver (with any explicit enhancement), or just the explicitly set resolver.

Returns:

the EntityResolver in use by the merger.

setEntityResolver

public void setEntityResolver(EntityResolver resolver,
 boolean fallbackToDefaultCatalogResolver)
                       throws IllegalStateException

Sets the EntityResolver to use during the comparison.

By default, the Apache Commons Resolver is used as an EntityResolver. If you wish to use a different one, set it up using this method. Note you can turn off the default catalog support by providing a null resolver and setting the fallbackToDefaultCatalogResolver to false.

Specified by:

setEntityResolver in interface MergeBase

Parameters:

resolver - The resolver to use. Using null removes an existing resolver.

fallbackToDefaultCatalogResolver - Sets whether to use the inbuilt catalog resolver if the provided resolver fails to resolve the entity.

Throws:

IllegalStateException - Thrown if the merger object's state is not INITIAL or RESET.

reset

public void reset()

Reverts the state of the merger to the point where MergeCommon.setAncestor(java.io.File, String) can be used. This is useful if you want to perform a new merge with the same configuration settings.

The merger has a state machine to control the proper ordering of setAncestor and addVersion methods. reset() is used to clear the ancestor and version state. After calling reset() a new ancestor should be provided.

It does not completely re-initialize a merger to the state it would have after calling the constructor, in particular settings for catalogs, entity resolvers and word by word are preserved through a reset method (methods are provided to change these settings, alternatively you can create a new merger object via the constructor).

Specified by:

reset in interface MergeBase

getCurrentState

public ConcurrentMergeState getCurrentState()

Returns the current state of the merge object. The state affects which methods can be validly be called, this is documented in the ConcurrentMergeState enum.

Returns:

The current state of the merge object.

setFormatExtractionPriorityList

public void setFormatExtractionPriorityList(List<String> priorityList)

Merge operations represent overlapping hierarchies from the input documents by flattening and subsequently fragmenting formatting elements where necessary.

To produce a result without overlapping or nesting of formatting elements, it may be necessary to remove formatting information in a controlled way.

The format extraction priority list specifies the list of versions by priority. This priority list will be used to extract formatting to resolve overlaps and nesting to produce a deltaV2 result.

Please note that if only some, not all, of the versions are specified in the priority list there is a possibility of format loss due to additions/deletions of formatting by the missing version(s).

Specified by:

setFormatExtractionPriorityList in interface MergeBase

Parameters:

priorityList - a list of priority versions specified using Strings

getFormatExtractionPriorityList

public List<String> getFormatExtractionPriorityList()

Reports the current setting of the format extraction priority list.

Specified by:

getFormatExtractionPriorityList in interface MergeBase

Returns:

the current list of priority versions
