Method Details

deleteChar

public MultilineEdit.ModificationResult deleteChar(int pos,
 int line)

Specified by:

deleteChar in interface MultilineEdit.Model

deleteRegion

public MultilineEdit.ModificationResult deleteRegion(int fromX,
 int fromY,
 int toX,
 int toY)

Specified by:

deleteRegion in interface MultilineEdit.Model

insertRegion

public MultilineEdit.ModificationResult insertRegion(int x,
 int y,
 String[] text)

Specified by:

insertRegion in interface MultilineEdit.Model

putChars

public MultilineEdit.ModificationResult putChars(int pos,
 int line,
 String str)

Description copied from interface: MultilineEdit.Model

Puts one or several characters at some position. The position expects to be valid in the content of the model, except of the case when there are no lines at all, lineIndex equals to zero and pos equals to zero. In this case the method must insert one empty line prior to making any required changes.

After performing the operation, the method must prepare the MultilineEdit.ModificationResult object. If the chars arguments has the length greater than one, the string argument of the result must be set to the value of chars argument.

If chars argument has the length equals to one, this single character must be returned as the character argument of the result. If the method is requested to insert a single spacing character, the string argument of the result must contain the last word prior to the inserting position. If there is no any word prior to the inserting position, the result may have the string argument empty.

Specified by:

putChars in interface MultilineEdit.Model

Parameters:

pos - The position on the line to put characters at

line - The index of the line to put characters on

str - The characters to put

Returns:

The MultilineEdit.ModificationResult object with the flag if the operation was performed and other corresponding information

mergeLines

public MultilineEdit.ModificationResult mergeLines(int firstLineIndex)

Specified by:

mergeLines in interface MultilineEdit.Model

splitLine

public MultilineEdit.ModificationResult splitLine(int pos,
 int line)

Description copied from interface: MultilineEdit.Model

Splits the specified line at the specified position. This method removes on the line all the content after the specified position and puts the deleted fragment on new line which is inserted just after modified. If the position is given outside of the stored text, the behaviour of this method is undefined.

Specified by:

splitLine in interface MultilineEdit.Model

Parameters:

pos - The 0-based position to split line at

line - The 0-based index of the line to split

Returns:

The fragment moved onto newly inserted line

doEditAction

public MultilineEdit.ModificationResult doEditAction(TextEditAction action)

Specified by:

doEditAction in interface MultilineEditCorrector

commit

public boolean commit()

getLineCount

public int getLineCount()

Specified by:

getLineCount in interface Lines

getLine

public String getLine(int index)

Specified by:

getLine in interface Lines

getHotPointX

public int getHotPointX()

Specified by:

getHotPointX in interface MultilineEdit.Model

getHotPointY

public int getHotPointY()

Specified by:

getHotPointY in interface MultilineEdit.Model

getTabSeq

public String getTabSeq()

Specified by:
