Libraries.Language.Compile.Parsing.QuorumLexer Documentation
This is a default class named Main. It has one action, also named Main, that starts the program.
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(file)
Inherits from: Libraries.Language.Object, Libraries.Language.Compile.Parsing.Lexer
Actions Documentation
Add(Libraries.Language.Compile.Parsing.Token token)
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.
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
Example
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
Empty()
This action empties the list of tokens.
Equals(Libraries.Language.Object object)
This action determines if two objects are equal based on their hash code values.
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
Example
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
GetCompilerErrorManager()
This action is used to read a text file and converts it into a token strea.
Return
Example
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(file)
GetFile()
Return
GetHashCode()
This action gets the hash code for an object.
Return
integer: The integer hash code of the object.
Example
Object o
integer hash = o:GetHashCode()
GetIgnoreWhiteSpace()
Return
boolean
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
GetSize()
This action returns the number of tokens in the token stream.
Return
integer: The number of tokens in the stream.
GetToken(integer i)
This method returns a token at a particular position in the lex.
Parameters
- integer i: The index of the token to get
Return
IsEmpty()
This action Returns whether or not there are tokens in the token stream
Return
boolean: a boolean value to indicate if the stream is empty.
Read(Libraries.System.File file)
This action is used to read a text file and converts it into a token strea.
Parameters
- Libraries.System.File: The file to read and lex.
Example
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(file)
Read(text value)
This action is used to read a text value and converts it into a token stream.
Parameters
- text value: The text value to lex.
Example
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(file:Read())
SetCompilerErrorManager(Libraries.Language.Compile.CompilerErrorManager compilerErrorManager)
SetFile(Libraries.System.File file)
Parameters
SetIgnoreWhiteSpace(boolean ignoreWhiteSpace)
Parameters
- boolean ignoreWhiteSpace
