Methods (Including Private)

method %OnNew() as %Status [ Language = objectscript ]
Inherited description: This callback method is invoked by the %New() method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

classmethod Insert(array, obj) [ Language = objectscript ]
method dsGetErrorHTML(code, msg, expr, start, end) [ Language = objectscript ]

Evaluate a node within a parse tree
method findFunctionInFunctionSet(func) [ Language = objectscript ]
classmethod get(arg, defvalue) [ Language = objectscript ]
method getPrecedence(op) [ Language = objectscript ]
Return the precedence value for the given operator.
method getTree() [ Language = objectscript ]
Get the parse tree.
method isBinaryOperator(ch) [ Language = objectscript ]
method isExpressionBalanced(expr) [ Language = objectscript ]
Make a pass over expression and make sure parens and quotes are balanced
method isFunction(token) [ Language = objectscript ]
test if token is a supported function name
method isIdentChar(ch, start) [ Language = objectscript ]

method isSpecialChar(ch) [ Language = objectscript ]
method isUnaryOperator(ch) [ Language = objectscript ]
method isUnaryOperatorChar(ch) [ Language = objectscript ]
classmethod isValidClassName(token) [ Language = objectscript ]
test if token is a valid class name
classmethod isValidIdent(token) [ Language = objectscript ]
test if complete token is a valid identifier
method isWhiteSpace(ch) [ Language = objectscript ]
classmethod lastIndexOf(string, substring) [ Language = objectscript ]
method parse(expr) [ Language = objectscript ]
Parse a DeepSee formula.
method reduceFunction(tokens, offset, expr) [ Language = objectscript ]
Reduce a function within a token list. Return index of next token.
method reduceTokens(tokens, expr) [ Language = objectscript ]
Reduce the token list (tokens) into a parse tree (expr) and return the top node of it.
method setFunctionSet(funcSet) [ Language = objectscript ]
Connect a function set to the parser.
method setTree(tree) [ Language = objectscript ]
Set the parse tree directly.
method testPrecedence(op1, op2) [ Language = objectscript ]
Test if op1 has precendence over op2
method tokenize(expr) [ Language = objectscript ]
tokenize a DeepSee formula; return a list of tokens. each token is of the form: {type:ident|func|,|(|)|unary|op|string|number , value:value} In ObjectScript the tokenList is a list of parseTreeNodes.
