Properties

Current

Get the current string.

Declaration
public virtual string Current { get; }
Property Value
Type Description
string

CurrentBuffer

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 CurrentBufferLength to determine the valid length of the returned buffer. For example, many words are stemmed simply by subtracting from the length to remove suffixes.
Declaration
public virtual char[] CurrentBuffer { get; }
Property Value
Type Description
char[]

CurrentBufferLength

Get the valid length of the character array in CurrentBuffer

Declaration
