Libraries.Data.Formats.JavaScriptObjectNotationParser Documentation
This class is used by the JavaScriptObjectNotation object to read in JavaScriptObjectNotation (JSON) formatted data from text values or from disk. It can be used directly by an advanced user who wants to perform custom parsing.
Example Code
use Libraries.Data.Formats.JavaScriptObjectNotation
use Libraries.Data.Formats.JavaScriptObjectNotationDefaultListener
use Libraries.Data.Formats.JavaScriptObjectNotationLexer
use Libraries.Data.Formats.JavaScriptObjectNotationParser
private action ReadToObject(text value) returns JavaScriptObjectNotation
if value = undefined
return undefined
end
JavaScriptObjectNotationDefaultListener listen
JavaScriptObjectNotationLexer lex
JavaScriptObjectNotationParser parse
lex:SetListener(listen)
parse:SetListener(listen)
lex:Read(value)
parse:Parse(lex)
return listen:GetObject()
end
Inherits from: Libraries.Language.Object

Actions Documentation
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 (smaller)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
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(t)
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
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.
GetListener()
This method is used to get the JavaScriptObjectNotationListener object used by the parser.
Example Code
use Libraries.Data.Formats.JavaScriptObjectNotationListener
use Libraries.Data.Formats.JavaScriptObjectNotationParser
action GetParserListener(JavaScriptObjectNotationParser parse) returns JavaScriptObjectNotationListener
return parse:GetListener()
end
Return
Libraries.Data.Formats.JavaScriptObjectNotationListener: The JavaScriptObjectNotationListener.
Parse(Libraries.Data.Formats.JavaScriptObjectNotationLexer lexerLocal)
This method is used to start the JavaScriptObjectNotation parser.
Example Code
use Libraries.Data.Formats.JavaScriptObjectNotation
use Libraries.Data.Formats.JavaScriptObjectNotationDefaultListener
use Libraries.Data.Formats.JavaScriptObjectNotationLexer
use Libraries.Data.Formats.JavaScriptObjectNotationParser
private action ReadToObject(text value) returns JavaScriptObjectNotation
if value = undefined
return undefined
end
JavaScriptObjectNotationDefaultListener listen
JavaScriptObjectNotationLexer lex
JavaScriptObjectNotationParser parse
lex:SetListener(listen)
parse:SetListener(listen)
lex:Read(value)
parse:Parse(lex)
return listen:GetObject()
end
Parameters
SetListener(Libraries.Data.Formats.JavaScriptObjectNotationListener listener)
This method is used to set the JavaScriptObjectNotationListener object used by the parser.
Example Code
use Libraries.Data.Formats.JavaScriptObjectNotation
use Libraries.Data.Formats.JavaScriptObjectNotationDefaultListener
use Libraries.Data.Formats.JavaScriptObjectNotationLexer
use Libraries.Data.Formats.JavaScriptObjectNotationParser
private action ReadToObject(text value) returns JavaScriptObjectNotation
if value = undefined
return undefined
end
JavaScriptObjectNotationDefaultListener listen
JavaScriptObjectNotationLexer lex
JavaScriptObjectNotationParser parse
lex:SetListener(listen)
parse:SetListener(listen)
lex:Read(value)
parse:Parse(lex)
return listen:GetObject()
end
Parameters
- Libraries.Data.Formats.JavaScriptObjectNotationListener: The JavaScriptObjectNotationListener listener to set.
