Libraries.Language.Compile.Parsing.Lexer

This is a general purpose class for defining lexers in Quorum. Subclasses implement the interface how they see fit for particular languages.

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action empties the list of tokens.

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns an iterator over the tokens. We can use this to automatically iterate over non-documentation tokens, to do lookahead and look back, and other operations that are harder to manage through the raw Get action.

This action returns the number of tokens in the token stream.

This method returns a token at a particular position in the lex.

This action Returns whether or not there are tokens in the token stream

This action is used to read a text file and converts it into a token stream.

This action is used to read a text value and converts it into a token stream. Subclasses for particular languages define how they read and manage errors.
