Classes
-
AbstractTokenizer
-
Implements an abstract tokenizer class.
-
AbstractVariantOperations
-
-
CalculationStack
-
Implements a stack of Variant values.
-
This state will either delegate to a comment-handling state, or return a token with just a slash in it.
-
CharReferenceInterval<T>
-
Represents a character interval that keeps a reference.
This class is internal and used by CharReferenceMap.
-
CharReferenceMap<T>
-
This class keeps references associated with specific characters
-
CharValidator
-
-
This state will either delegate to a comment-handling state, or return a token with just a slash in it.
-
CsvConstant
-
The CsvConstant class defines a set of constants, such as control return, line feed and null.
-
CsvQuoteState
-
Implements a quote string state object for CSV streams.
-
CsvSymbolState
-
Implements a symbol state to tokenize delimiters in CSV streams.
-
CsvTokenizer
-
Implements a tokenizer class for CSV files.
-
CsvWordState
-
Implements a word state to tokenize CSV stream.
-
DefaultFunctionCollection
-
Implements a list filled with standard functions.
-
DelegatedFunction
-
Defines an interface for expression function.
-
ExpressionCalculator
-
Implements an expression calculator class.
-
ExpressionNumberState
-
Implements an Expression-specific number state object.
-
ExpressionParser
-
Implements an expression parser class.
-
ExpressionQuoteState
-
Implements an Expression-specific quote string state object.
-
ExpressionSymbolState
-
Implements a symbol state object.
-
ExpressionToken
-
-
ExpressionTokenizer
-
-
ExpressionWordState
-
Implements a word state object.
-
FunctionCollection
-
Implements a functions list.
-
A CommentState object returns a comment from a scanner.
-
GenericNumberState
-
A NumberState object returns a number from a scanner. This state's idea of a number allows
an optional, initial minus sign, followed by one or more digits. A decimal point and another string
of digits may follow these digits.
-
GenericQuoteState
-
A quoteState returns a quoted string token from a scanner.
-
GenericSymbolState
-
The idea of a symbol is a character that stands on its own, such as an ampersand or a parenthesis.
-
GenericTokenizer
-
Implements a default tokenizer class.
-
GenericWhitespaceState
-
A whitespace state ignores whitespace (such as blanks and tabs), and returns the tokenizer's
next token. By default, all characters from 0 to 32 are whitespace.
-
GenericWordState
-
A
wordState returns a word from a scanner. Like other states, a tokenizer transfers the job
of reading to this state, depending on an initial character. Thus, the tokenizer decides
which characters may begin a word, and this state determines which characters may appear
as a second or later character in a word. These are typically different sets of characters;
in particular, it is typical for digits to appear as parts of a word, but not
as the initial character of a word.
-
Defines an interface for tokenizer state that processes comments.
-
IFunction
-
Defines an interface for expression function.
-
IFunctionCollection
-
Defines a functions list.
-
INumberState
-
Defines interface for tokenizer state that processes numbers - Integers, Floats, HexDec..
-
IQuoteState
-
Defines an interface for tokenizer state that processes quoted strings.
-
IScanner
-
Defines scanner that can read and unread characters and count lines.
This scanner is used by tokenizers to process input streams.
-
ISymbolState
-
Defines an interface for tokenizer state that processes delimiters.
-
ITokenizer
-
A tokenizer divides a string into tokens.
-
ITokenizerState
-
A tokenizerState returns a token, given a scanner, an initial character read from the scanner,
and a tokenizer that is conducting an overall tokenization of the scanner. The tokenizer will
typically have a character state table that decides which state to use, depending on an initial
character. If a single character is insufficient, a state such as SlashState
will read a second character, and may delegate to another state, such as SlashStarState.
This prospect of delegation is the reason that the nextToken()
method has a tokenizer argument.
-
IVariable
-
Defines a variable interface.
-
IVariableCollection
-
Defines a variables list.
-
IVariantOperations
-
Defines an interface for variant operations manager.
-
IWhitespaceState
-
Defines an interface for tokenizer state that processes whitespaces (' ', '\t')
-
IWordState
-
Defines an interface for tokenizer state that processes words, identificators or keywords
-
MustacheErrorCode
-
General syntax errors.
-
MustacheParser
-
Implements an mustache parser class.
-
MustacheSpecialState
-
Implements a quote string state object for Mustache templates.
-
MustacheTemplate
-
Implements an mustache template class.
-
MustacheToken
-
-
MustacheTokenizer
-
-
StringScanner
-
-
SymbolNode
-
A SymbolNode object is a member of a tree that contains all possible prefixes
of allowable symbols. Multi-character symbols appear in a SymbolNode tree
with one node for each character.
-
SymbolRootNode
-
This class is a special case of a SymbolNode. A SymbolRootNode
object has no symbol of its own, but has children that represent all possible symbols.
-
SyntaxErrorCode
-
General syntax errors.
-
Token
-
A token represents a logical chunk of a string. For example, a typical tokenizer would break
the string "1.23 <= 12.3" into three tokens: the number 1.23, a less-than-or-equal symbol,
and the number 12.3. A token is a receptacle, and relies on a tokenizer to decide precisely how
to divide a string into tokens.
-
TypeSafeVariantOperations
-
Implements a strongly typed (type safe) variant operations manager object.
-
TypeUnsafeVariantOperations
-
Implements a type unsafe variant operations manager object.
-
Variable
-
Implements a variable holder object.
-
VariableCollection
-
Implements a variables list.
-
Variant
-
Defines container for variant values.
