Method Details

setCurrent

public void setCurrent(String value)

Set the current string.

getCurrent

public String getCurrent()

Get the current string.

setCurrent

public void setCurrent(char[] text,
 int length)

Set the current string.

Parameters:

text - character array containing input

length - valid length of text.

getCurrentBuffer

public char[] getCurrentBuffer()

Get the current buffer containing the stem.

NOTE: this may be a reference to a different character array than the one originally provided with setCurrent, in the exceptional case that stemming produced a longer intermediate or result string.

It is necessary to use getCurrentBufferLength() to determine the valid length of the returned buffer. For example, many words are stemmed simply by subtracting from the length to remove suffixes.

public int getCurrentBufferLength()
