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

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.

Parameters

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)

Equals(Libraries.Language.Object object)

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

Parameters

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)

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()

GetListener()

This method is used to get the JavaScriptObjectNotationListener object used by the parser.

Return

Libraries.Data.Formats.JavaScriptObjectNotationListener: The JavaScriptObjectNotationListener.

Example

use Libraries.Data.Formats.JavaScriptObjectNotationListener
use Libraries.Data.Formats.JavaScriptObjectNotationParser

action GetParserListener(JavaScriptObjectNotationParser parse) returns JavaScriptObjectNotationListener
    return parse:GetListener()
end

Parse(Libraries.Data.Formats.JavaScriptObjectNotationLexer lexerLocal)

This method is used to start the JavaScriptObjectNotation parser.

Parameters

Example

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

SetListener(Libraries.Data.Formats.JavaScriptObjectNotationListener listener)

This method is used to set the JavaScriptObjectNotationListener object used by the parser.

Parameters

Example

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
