Write the document as JSON to a stream.
This method validates an object.
The
%Save method of a persistent class calls this method before filing any objects in the database. The%ValidateObject of a referencing object can call it. You can also call it explicitly at any time.
%ValidateObject does the following:
- If present, it will call a user-supplied
%OnValidateObject method.- It checks if any required property values are missing.
- If the PROPERTYVALIDATION class parameter is set to ValidateOnSave, it validates each non-null property value by calling the property method IsValid on each literal property and the %ValidateObject method for each object-valued embedded object property (properties whose type extend %SerialObject).
- If checkserial is 1, it forces the checking of any embedded object properties by calling their %ValidateObject method after swizzling this property.
- If checkserial is 2, it forces the checking of any collections of serial types by iterating over those collections and calling their
%ValidateObject method after swizzling this property, in addition to the validation that occurs when checkserial is 1.
%ValidateObject returns a %Status indicating success or error. It is up to the caller to process the error value.
%ValidateObject does not validate object-valued reference properties (properties whose type extends %Persistent) due to the possibility of circular dependencies between objects. The%Save method of a persistent class automatically detects and handles circular references between objects. If you require the validation of reference properties, you can override this method in a subclass or call%Save directly.
Constructs array(key)=value for each element in the serialval value.Returns a
%Status value indicating success or failure.
Clears the contents of the array.Returns a
%Status value indicating success or failure.
Returns the number of elements contained in the array.
DocumentExists() returns a boolean value indicate whether or not the documentID exists in the global/local variable reference (GLVN).
Parameters pWhere Input Global or local variable reference where documents are stored.
pDocumentID Input The document ID.
Starting from, but not including, location key, finds the next element in the array with value equal to element.If key is a null string (""), the search starts at the beginning of the array.
Find returns the key associated with the found element or null string ("") if no element is found.
Finds and returns the value of the element at position key in the list.GetAt returns the value of the element at location key or null string ("") if no element is found.
Finds and returns the value of the element at the location after key in the array. If key is a null string (""), it returns the value of the first element in the array.The value of key, which is passed by reference, is updated to the key value of the returned element or null string ("") if key is at the end of the array.
Finds and returns the value of the element at the location before key in the array. If key is a null string (""), it returns the value of the last element in the array.The value of key, which is passed by reference, is updated to the key value of the returned element or null string ("") if key is at the beginning of the array.
Inserts an element with value element at the end of the list.Returns a
%Status value indicating success or failure.
Inserts an element with value element at position key.To make room for the new element, the elements previously at or following position key are moved up by one position.
key must be in the following range:
Returns a1 <= key <= Count() + 1%Status value indicating success or failure.
Inserts a list with value inslist at the end of the list.Returns a
%Status value indicating success or failure.
Inserts an element with value element into the list at the correct ordered position. The elements in the list are shifted to accommodate the new element as necessary.Returns a
%Status value indicating success or failure.
Returns true (1) if a value is defined at location key, otherwise false (0).
Converts the serial state of this array object to a delimited string using the value of the ODBCDELIMITER parameter as a delimiter.
Converts the value of an incoming delimited string to a serialized state using the value of the ODBCDELIMITER parameter as a delimiter.
Finds and returns the key value of the element at the location preceding key in the array. If key is a null string (""), thenNext returns the key value for the last element in the array.
Removes the element at position key in the list. The elements following position key are moved to fill in the resulting gap.RemoveAt returns the value of the removed element or null string ("") if no element was removed.
Sets the value of the element at position key to element.Returns a
%Status value indicating success or failure.
%Document.Object contructor that populates the document content from an XML source. pXML can either be a counted array of lines, a stream object, or...
deswizzle serializes a %Document object into CSON format.
loadResult
OpenDocument will retrieve a previously saved document from the specified global or local variable reference (GLVN) with the specified pDocumentID and return an oref referencing an instance of %ZEN.proxyObject. If a document with the specified ID does not exist in that GLVN then OpenDocument will return an error in the output pStatus parameter.
Parameters pWhere Input Global or local variable reference. This is the location where the proxyObject instance will be saved.
pDocumentID Input The ID of the document to be opened.
pStatus Output The returned %Status value, indicating success or failure.
Save the Document to a global or local variable reference (GLVN) with the specified pDocumentID. If a document with the same ID already exists in that GLVN then an error %Status value is returned.
Parameters pWhere Input Global or local variable reference. This is the location where the %Document instance will be saved.
pDocumentID Input The document ID. This value must be unique within the GLVN specified in pWhere.
Display the current object and all nested objects.
swizzle converts a CSON object value into the current object.
