putChars
public MultilineEdit.ModificationResult putChars(int pos, int lineIndex, 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 andpos
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 thechars
arguments has the length greater than one, the string argument of the result must be set to the value ofchars
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 interfaceMultilineEdit.Model
- Parameters:
pos
- The position on the line to put characters atlineIndex
- The index of the line to put characters onstr
- 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 interfaceMultilineEdit.Model
-
splitLine
public MultilineEdit.ModificationResult splitLine(int pos, int lineIndex)
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 interfaceMultilineEdit.Model
- Parameters:
pos
- The 0-based position to split line atlineIndex
- The 0-based index of the line to split- Returns:
- The fragment moved onto newly inserted line
