Io Class [AX 2012]
The Io class serves as the base class for the format-specific Io classes, which are used to access external files.
| Method | Description | |
|---|---|---|
| cancelTimeOut | Cancels a previous method call to the setTimeOut method. (Inherited from Object.) |
| equal | Determines whether the specified object is equal to the current one. (Inherited from Object.) |
| finalize | Closes the file and, if data was written, flushes the file buffers to disk. |
| getTimeOutTimerHandle | Returns the timer handle for the object. (Inherited from Object.) |
| handle | Retrieves the handle of the class of the object. (Inherited from Object.) |
| inFieldDelimiter | Determines the delimiter used to separate fields in records accessed by the *Io classes. |
| inRecordDelimiter | Determines to the *Io classes what character or characters to search for to determine whether a full record has been read. |
| inRecordLength | Gets or sets the number of characters to read for each record in a file. |
| new | Creates a new instance of the Io class. (Overrides the new Method.) |
| notify | Releases the hold on an object that has called the wait method on this object. (Inherited from Object.) |
| notifyAll | Releases a lock on the object that was issued by the wait method on this object. (Inherited from Object.) |
| objectOnServer | Determines whether the object is on a server. (Inherited from Object.) |
| outFieldDelimiter | Gets or sets the sequence of characters that are written to a file that is used to separate the fields of a record. |
| outRecordDelimiter | Gets or sets the sequence of characters that is written to the output files, which separate the records in the output files. |
| owner | Returns the instance that owns the object. (Inherited from Object.) |
| read | Reads the next full record from the Io object. |
| setTimeOut | Sets up the scheduled execution of a specified method. (Inherited from Object.) |
| status | Retrieves the status of the last operation performed on the Io object. |
| toString | Returns a string that represents the current object. (Inherited from Object.) |
| usageCount | Returns the current number of references, that is, the value of the reference counter, that the object has. (Inherited from Object.) |
| wait | Pauses a process. (Inherited from Object.) |
| write | Writes values of a simple type. |
| writeExp | Writes the content of a container to the file. |
| xml | Returns an XML string that represents the current object. (Inherited from Object.) |
The basic Io class features no actual data I/O but works as base class for the format-specific Io classes. The methods that are common to all Io classes are described here. For format-specific features and behavior of the member functions, refer to the documentation for each of the I/O classes.
To support reading and writing of different formats of external files, MorphX features a range of different Io classes: for comma-separated files, for comma-separated 7 bit files, for binary files, and for plain-text files.
