com.ibm.richtext.styledtext.MText.replace()
Replace the characters and styles in the range [start, limit) with the characters and styles in srcText in the range [srcStart, srcLimit). srcText is not modified. @param start the offset at which the replace operation begins @param limit the offset at which the replace operation ends. The character and style atlimit is not modified. @param srcText the source for the new characters and styles @param srcStart the offset into srcText where new characters and styles will be obtained @param srcLimit the offset into srcText where the new characters and styles end
