Class SequentialMerge

java.lang.Object

com.deltaxml.merge.SequentialMerge

All Implemented Interfaces:

MergeBase

public class SequentialMerge
extends Object
implements MergeBase

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

The term sequential describes a scenario in which the each of the versions added to the merge would be a derivative of the previous version. Such a merge would be 'non-concurrent'.

Since:

6.0

Constructor Details

SequentialMerge

public SequentialMerge()

Constructs a new SequentialMerge instance.

Default settings

After construction the SequentialMerge 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

reset

public void reset()

Reverts the state of the merger to the point where first version can be added. This is useful if you want to perform a new merge with the same configuration settings.

Method reset() is used to clear the version state. After calling reset(), the new versions 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).

Adds a version with a File input.

The version parameter appears in the result file and must correspond to the NMTOKEN production rule in the XML Specification (the same production rule is used in both XML 1.0 and XML 1.1). This precludes the use of the '!' (0x21) and '=' (0x3d) characters used for version delimiting and other characters which could cause confusion such as the space character.

Specified by:

addVersion in interface MergeBase

Parameters:

file - The input file which is the version to be added.

version - The string to use as the name of the version. This appears in the deltaxml:deltaV2 attributes in the result. This cannot contain '=' or '!' characters.

Throws:

IllegalStateException - Thrown if the merge object's state is not STARTED or EXTRACTABLE.

IllegalArgumentException - Thrown if the version parameter is not an NMTOKEN, if a version has already been added with this name, or if the supplied name is the same as the ancestor version.

FileNotFoundException - Thrown if the provided file object does not exist.

DifferentRootElementException - Thrown if the version added has a different root XML element as the ancestor.

InvalidInputException - Thrown if the input is invalid.

com.deltaxml.licensing.LicenseException - Thrown if there is no license installed, or if the installed license is invalid.

UnorderedDuplicateKeysException - Thrown if there are duplicate keys in orderless merge.

DifferingOrderedAttributesException - Thrown if inputs have different deltaxml:ordered attribute values.

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
