java.lang.Object

org.tribuo.util.tokens.impl.NonTokenizer

All Implemented Interfaces:

public class NonTokenizer
extends Object
implements Tokenizer

A convenience class for when you are required to provide a tokenizer but you don't actually want to split up the text into tokens. This tokenizer will serve up a single "token" corresponding to the input text.

public NonTokenizer()

Method Detail

getProvenance

public com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance getProvenance()

Specified by:

getProvenance in interface com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>

reset

public void reset(CharSequence cs)

Description copied from interface: Tokenizer

Resets the tokenizer so that it operates on a new sequence of characters.

Specified by:

reset in interface Tokenizer

Parameters:

cs - a character sequence to tokenize

advance

public boolean advance()

Description copied from interface: Tokenizer

Advances the tokenizer to the next token.

Specified by:

advance in interface Tokenizer

Returns:

true if there is such a token, false otherwise.

getText

public String getText()

Description copied from interface: Tokenizer

Gets the text of the current token, as a string

Specified by:

getText in interface Tokenizer

Returns:

the text of the current token

getStart

public int getStart()

Description copied from interface: Tokenizer

Gets the starting character offset of the current token in the character sequence

Specified by:

getStart in interface Tokenizer

Returns:

the starting character offset of the token

getEnd

public int getEnd()

Description copied from interface: Tokenizer

Gets the ending offset (exclusive) of the current token in the character sequence

Specified by:

getEnd in interface Tokenizer

Returns:

the exclusive ending character offset for the current token.

getType

public Token.TokenType getType()

Description copied from interface: Tokenizer

Gets the type of the current token.

Specified by:

getType in interface Tokenizer

Returns:

the type of the current token.

clone

public NonTokenizer clone()

Description copied from interface: Tokenizer

Clones a tokenizer with it's configuration. Cloned tokenizers are not processing the same text as the original tokenizer and need to be reset with a fresh CharSequence.

Specified by:

clone in interface Tokenizer

Overrides:

clone in class Object

Returns:

A tokenizer with the same configuration, but independent state.
