use Libraries.Language.Compile.CompilerErrorManager
QuorumLexer lexer
File file
file:SetPath("file.quorum")
CompilerErrorManager errors

Add(Libraries.Language.Compile.Parsing.Token token)
The raw tokens from the le
Parameters
Compare(Libraries.Language.Object object)
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 (smalle
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
Empty()
This action empties the list of token
Equals(Libraries.Language.Object object)
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(
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
GetCompilerErrorManager()
This action is used to read a text file and converts it into a token strea.
Example Code
use Libraries.System.File
use Libraries.Language.Interpreter.QuorumLexer
use Libraries.Language.Compile.CompilerErrorManager
QuorumLexer lexer
File file
file:SetPath("file.quorum")
CompilerErrorManager errors
lexer:SetCompilerErrorManager(errors)
lexer:Read(fil
Return
Libraries.Language.Compile.CompilerErrorManager:
GetFile()
Return
GetHashCode()
This action gets the hash code for an object.
Example Code
Object o
integer hash = o:GetHashCode
Return
integer: The integer hash code of the object.
GetIterator()
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.
Return
Libraries.Language.Compile.Parsing.TokenIterator: TokenIterator This action returns the number of tokens in the token stream. integer: The number of tokens in the strea This method returns a token at a particular position in the lex. Libraries.Language.Compile.Parsing.Token: This action Returns whether or not there are tokens in the token stream boolean: a boolean value to indicate if the stream is empt This action is used to read a text file and converts it into a token strea. Example Code This action is used to read a text value and converts it into a token stream. Example CodeGetSize()
