Enum TokenizerState

java.lang.Object
  java.lang.Enum<TokenizerState>
      com.codemesh.terp.api.TokenizerState

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TokenizerState>

public enum TokenizerState
extends java.lang.Enum<TokenizerState>

The supported tokenizer states. Tokenizer states are used to switch between different interpretations of the same character depending on the mode or state that the tokenizer is in.

When the tokenizer is in EXPRESSION mode, the input 3+4 will result in three tokens (numeric literal, plus, numeric literal). When the tokenizer is in TEXT mode, the result will be one text token containing the full expression "3+4" as a string. SCRIPT mode is an extension of EXPRESSION mode. In SCRIPT mode, the semicolon is interpreted as an expression terminator that may preceed an additional expression (list).

Method Detail

values

public static TokenizerState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TokenizerState c : TokenizerState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TokenizerState valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
