Class NonTokenizer

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()
      Constructs a NonTokenizer.

  • Method Details

    • 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.
