Method Detail

incrementToken

public final boolean incrementToken()
                             throws IOException

Deprecated.

Specified by:

incrementToken in class TokenStream

Throws:

IOException

decompose

protected abstract void decompose()

Deprecated.

Decomposes the current termAtt and places Lucene43CompoundWordTokenFilterBase.CompoundToken instances in the tokens list. The original token may not be placed in the list, as it is automatically passed through this filter.

reset

public void reset()
           throws IOException

Deprecated.

Overrides:

reset in class TokenFilter

Throws:

IOException
