Constructor Detail

TextPieceInfoImpl

public TextPieceInfoImpl(String nodeID,
                         int offset,
                         int originalOffset,
                         String text)

Constructor.

Parameters:

nodeID - id of text node of text piece

offset - of first character in displayed text of text node

originalOffset - offset of first character in original text of text node

text - text from textual node with id nodeID and starting at position offset

Method Detail

getID

public String getID()

Returns id for text piece in this TextPieceInfo. Text piece id is unique identifier for substring of text of textual node from xml document. Id is build by adding offset and length to id of textual node containig this text. The id has format: id of node

Specified by:

getID in interface ITextPieceInfo

Returns:

text piece id : id of node

getNodeID

public String getNodeID()

Description copied from interface: ITextPieceInfo

Identification of node holding the text (text node, cdata node, attribute).

Specified by:

getNodeID in interface ITextPieceInfo

Returns:

id of node containing this text

getOffset

public int getOffset()

Description copied from interface: ITextPieceInfo

Index of the first character of this text piece in whole displayed text of textual node.

Specified by:

getOffset in interface ITextPieceInfo

Returns:

globaloffset of first character

getLastIndex

public int getLastIndex()

Description copied from interface: ITextPieceInfo

Index of last character of this text piece in whole displayed text

Specified by:

getLastIndex in interface ITextPieceInfo

Returns:

global offset of last character

getLength

public int getLength()

Description copied from interface: ITextPieceInfo

Length of the text piece.

Specified by:

getLength in interface ITextPieceInfo

Returns:

length

getText

public String getText()

Description copied from interface: ITextPieceInfo

Returns text of this text piece.

Specified by:

getText in interface ITextPieceInfo

Returns:

text value.

getNodeID

public static String getNodeID(String id)

Parses node id with multiplicity from id.

Parameters:

id - some id

Returns:

id of node

getParsedNodeId

public static final String getParsedNodeId(String nodeId)

Parses node id without multiplicity - anything include and after ":" is omitted.

Parameters:

nodeId - id of node

Returns:

id without multiplicity

getOffset

public static int getOffset(String id)

Parses offset of text piece from text piece id. If id is not text piece id, IllegalArgumentException is thrown.

Parameters:

id - id of text piece

Returns:

offset of text piece

getLength

public static int getLength(String id)

Parses length of text piece from text piece's id. If id is not text piece id, IllegalArgumentException is thrown.

Parameters:

id - id of text piece

Returns:

length of text piece

contains

@Deprecated
public int contains(String nodeID,
                               int offset,
                               int length)

Deprecated. ak sa ti to hodi pouzit informuj STUDVU

Specified by:

contains in interface ITextPieceInfo

Parameters:

nodeID - id of text node

offset - offset in text piece

Returns:

index of character from start of this text piece

isTextPieceId

public static boolean isTextPieceId(String id)

True if parameter id is text piece/selection id, it means of form int.

Parameters:

id - to examine

Returns:

true if id is textpiece/selection id

buildID

public static final String buildID(String nodeID,
                                   int offset,
                                   int length)

Static method to build text piece id from nodeID, offset and length.

Parameters:

nodeID - id of node of text piece

offset - of first character in text of text node

length - of text to identify

Returns:

nodeID

tidyUpIds

public static void tidyUpIds(List<String> ids)

Any text piece ids which are neighbour are joined together. Neighbour text piece ids are satisfiing these conditions: have same node id and offset + length - 1 == offset of second (where first ends, second starts).

Parameters:

ids - text piece ids to tidy up

getOriginalOffset

public int getOriginalOffset()

Description copied from interface: ITextPieceInfo

Index of the first character of this text piece in whole original text of textual node.

Specified by:

getOriginalOffset in interface ITextPieceInfo

Returns:

globaloffset of first character
