Methods
classmethod %BuildFunctionMetaData() as %Status
Test if function metadata is in the DeepSeeFunctionGLVN global.
If not, put it there.
final classmethod %GetFunctionInfo(pFunction As %String, Output pIsImplemented As %Boolean, Output pArgCount As %Integer, Output pReturns As %String, Output pArgTypes As %List, Output pArgDesc As %List) as %Boolean
Return meta-data for the function pFunction.
Returns true if the function exists.
On return, pIsImplemented if the function is implemented.
pArgCount returns the number of required arguments the function expects or "" if this function does not take arguments.
pReturns is the return type.
pArgTypes is a list of argument types for the function.
pArgDesc is a list of argument descriptors for the function.
On return, pIsImplemented if the function is implemented.
pArgCount returns the number of required arguments the function expects or "" if this function does not take arguments.
pReturns is the return type.
pArgTypes is a list of argument types for the function.
pArgDesc is a list of argument descriptors for the function.
Return a string containing the signature for the given function
(used for error messages).
method %GetType() as %String
Return type of this node.
classmethod %TypeFlagToString(pTypeFlag) as %String
Convert a ds Type to a printable string.
Used for error reporting.
