Class AS400File

  • java.lang.Object
    • com.ibm.as400.access.AS400File
  • All Implemented Interfaces:
    java.io.Serializable
    Direct Known Subclasses:
    KeyedFile, SequentialFile


    public abstract class AS400File
    extends java.lang.Object
    implements java.io.Serializable
    Represents a physical or logical file on the system. This class allows the user to do the following:
    • Create a physical file on the system by:
      • Specifying a record length.
      • Specifying an existing DDS source file.
      • Specifying a RecordFormat object that contains a description of the record format for the file.
    • Access the records in a system file sequentially, by record number, or by key. Note: To read a keyed physical or logical file sequentially and have the records returned in key order, use the read...() methods of KeyedFile.
    • Write records to a system file sequentially or by key.
    • Update records in a system file sequentially, by record number or by key.
    • Lock a system file for different types of access.
    • Use commitment control when accessing a system file. The user can:
      • Start commitment control for the connection.
      • Specify different commitment control lock levels for the individual files being accessed.
      • Commit and rollback transactions for the connection.
    • Delete a physical or logical file or member on the system.
    AS400File objects generate the following events:
    • FileEvent
      The events fired are:
      • FILE_CLOSED
      • FILE_CREATED
      • FILE_DELETED
      • FILE_MODIFIED
      • FILE_OPENED
    • PropertyChangeEvent
    • VetoableChangeEvent

                           java.io.IOException
        Creates a physical file with the specified record length and file type. The record format for this object will be set by this method. The record format for the file is determined as follows:
        • If fileType is AS400File.TYPE_DATA,
          • The format name of the file is the name of the file as specified on the constructor
          • The record format contains one field whose name is the name of the file, whose type is CHARACTER, and whose length is recordLength
        • If fileType is AS400File.TYPE_SOURCE,
          • The format name of the file is the name of the file as specified on the constructor
          • The record format contains three fields:
            • SRCSEQ whose type is ZONED(6, 2)
            • SRCDAT whose type is ZONED(6, 0)
            • SRCDTA whose type is CHARACTER and whose length is recordLength - 12
        Note: The file is created using the default values for the Create Physical File (CRTPF) command. To change the file after it has been created, use the CommandCall class to issue a CHGPF command.
        The name of the file and the system to which to connect must be set prior to invoking this method.
        Parameters:
        recordLength - The record length with which to create the file. Valid values are 1 through 32766 inclusive.
        fileType - The file type with which to create the file. Valid values are AS400File.TYPE_DATA or AS400File.TYPE_SOURCE. If AS400File.TYPE_DATA is specified, the record format for the file contains one field. If AS400File.TYPE_SOURCE is specified, the record format for the file contains three fields: source sequence number, date, and source statement.
        textDescription - The text description with which to create the file. This value must be 50 characters or less. If this value is null, the empty string, or AS400File.BLANK, the text description is blank.
        Throws:
        AS400Exception - If the system returns an error message.
        AS400SecurityException - If a security or authority error occurs.
        ConnectionDroppedException - If the connection is dropped unexpectedly.
        java.lang.InterruptedException - If this thread is interrupted.

      • open

        public void open(int openType,
                int blockingFactor,
                int commitLockLevel)
                  throws AS400Exception,
                         AS400SecurityException,
                         java.lang.InterruptedException,
                         java.io.IOException
        Opens the file. The file must not be open when invoking this method. If commitment control is not started for the connection, commitLockLevel is ignored. The file cursor is positioned prior to the first record. If blockingFactor is greater than one (or if zero is specified and a blocking factor greater than one is determined by the object) and the file is opened for READ_ONLY, the record cache will be filled with an initial set of records.
        The record format for the file must be set prior to calling this method.
        The name of the file and the system to which to connect must be set prior to invoking this method.
        Parameters:
        openType - The manner in which to open the file. Valid values are:
        • READ_ONLY
        • READ_WRITE
        • WRITE_ONLY
        If the openType is WRITE_ONLY, the various positionCursor() methods will fail since write() operations are appended to the end of the file.
        blockingFactor - The number of records to retrieve or to write during a read or write operation.
        The AS400File object will attempt to anticipate the need for data by accessing blocks of records if the openType is READ_ONLY.
        If the openType is WRITE_ONLY, blockingFactor number of records will be written at one time when writing an array of records.
        If the open type is READ_WRITE, blockingFactor is ignored and a blocking factor of 1 will be used for data integrity reasons. Specify an appropriate blockingFactor for your performance needs.
        If 0 is specified for blockingFactor, a default value will be calculated by taking the integer result of dividing 2048 by the byte length of the record plus 16.
        If the user specifies a blocking factor greater than 1 or specifies 0, which will cause a blocking factor to be calculated, there is the risk of obtaining stale data when doing multiple read operations. Invoke the refreshRecordCache() method prior to reading a record to cause the object to read from the system if this is a problem.
        commitLockLevel - Used to control record locking during a transaction if commitment control has been started for the connection. Valid values are:
        • COMMIT_LOCK_LEVEL_ALL
        • COMMIT_LOCK_LEVEL_CHANGE
        • COMMIT_LOCK_LEVEL_CURSOR_STABILITY
        • COMMIT_LOCK_LEVEL_DEFAULT
        • COMMIT_LOCK_LEVEL_NONE
        The commitLockLevel is ignored if commitment control is not started for the connection.
        Throws:
        AS400Exception - If the system returns an error message.
        AS400SecurityException - If a security or authority error occurs.
        ConnectionDroppedException - If the connection is dropped unexpectedly.
        java.lang.InterruptedException - If this thread is interrupted.
        java.io.IOException - If an error occurs while communicating with the system.

The cursor position is not changed when this method is invoked.
        Parameters:
        record - The record with which to update. The record must be a record whose format matches the record format of this object. To ensure that this requirement is met, use the RecordFormat.getNewRecord() method to obtain a default record whose fields can be set appropriately by the Java program and then written to the file.
        Throws:
        AS400Exception - If the system returns an error message.
        AS400SecurityException - If a security or authority error occurs.
