A token consists of a type (function, keyword, variable, etc), and a value (the piece of code that is classified as a single token of the same type).

Instances of this class are created by the classes implementing the {@link Tokenizer} interface. Token describes a portion of text according to the settings given to the producing {@link Tokenizer} in form of a {@link TokenizerProperties} object. Beside the token type the token image itself, its position in the input stream, line and column position and associated informations can be obtained from the Token (provided, the nessecary parse flags are set in the tokenizer).
This class replaces the older {@link de.susebox.java.util.Token} which isdeprecated.

This class defines special token identifiers: "token" (Token.TOKEN) and "ignored" (Token.IGNORED), which are needed when specifiying a syntax with mixed parser and lexer rules.
This class defines special symbols needed to define character sets with Token.UPTO (e.g. A..Z) and intersections with Token.BUTNOT (e.g. `char` - `newline`). @author (c) 2000, Fritz Ritzberger
Token is the security entity used by the framework to verify authenticity of any resource.
Typical Token reuse patterns:
return reusableToken.reinit(string, startOffset, endOffset[, type]);
return reusableToken.reinit(string, 0, string.length(), startOffset, endOffset[, type]);
return reusableToken.reinit(buffer, 0, buffer.length, startOffset, endOffset[, type]);
return reusableToken.reinit(buffer, start, end - start, startOffset, endOffset[, type]);
return reusableToken.reinit(source.termBuffer(), 0, source.termLength(), source.startOffset(), source.endOffset()[, source.type()]);
TokenStreams can be chained, one cannot assume that the Token's current type is correct.OMElements representing the token in its present state and the previous state. These tokens are stored using the storage mechanism provided via the TokenStorage interface.
@see org.apache.rahas.TokenStorage
A Token identifies an offset range within the document. Nodes and Attributes implementing this interface are identified by the {@link NodeTokenizer} and{@link AttributeTokenizer}.
Component that renders a transaction token input field, and then validates it on a subsequent form submit. The token component must be the last input component child of the parent form to be processed.

Token defines a set of constant properties that indicate basic token types. If you wish to define your own identifiers for tokens, you should start at Token.CUSTOM + 1. @see org.dmd.util.parsing.Classifier
IToken.
A Token is a piece of text representing some logical token in source code for a programming language. For example, the line of C code:
int i = 0;would be broken into 8
Tokens: the first representing int, the second whitespace, the third i, the fourth whitespace, the fifth =, etc.@author Robert Futrell @version 0.3
The Token class implements a token for the command grammar.

It is important that the keys assigned to tokens are sufficiently randomised and secured that they can serve as identifying a unique user session. Implementations of {@link TokenService}are free to use encryption or encoding strategies of their choice. It is strongly recommended that keys are of sufficient length to balance safety against persistence cost. In relation to persistence cost, it is strongly recommended that returned keys are small enough for encoding in a cookie.
@author Ben Alex @since 2.0.1It can be used in conjunction with a ParseLong() processor, since the token would be discovered before the parser attempt so parse the token as a number.
Comparison between column value and the token is based on the object's equals() method. @since 1.02 @author Kasper B. Graversen

Generally, it is painful to implement both the operation and operationReverse methods of this class. It is also painful to implement tokens that are automatically converted to other tokens in a consistent fashion. As such, there are several subclasses of this class that implement these methods and provide a somewhat nicer abstraction. The ScalarToken derived class is useful for many types that are losslessly convertible to other types and may be associated with units, such as IntToken. The MatrixToken derived class is useful for implementing matrices of ScalarTokens, such as IntMatrixToken. The AbstractNotConvertible derived class is useful for implementing tokens that are not losslessly convertible to a token in implemented in another class, such as ArrayToken. Lastly, AbstractConvertibleToken is useful for implementing tokens that are losslessly convertible to a token in another class, but don't have units, such as BooleanToken.
Instances of this base class *should not* be used to represent pure events, i.e., to indicate that an event is present. To represent pure events, it is better to use the EventToken class. The reasoning is that the type BaseType.GENERAL is reserved to represent types which the type system cannot represent exactly. Using the EventToken class, and the type BaseType.EVENT allows typesafe use of pure events.
Nil, null or missing tokens are common in analytical systems like R and SAS where they are used to handle sparsely populated data sources. This class has support for such tokens, see {@link #NIL} for details. @author Neil Smyth, Yuhong Xiong, Edward A.
