Interface FML

All Known Implementing Classes:
  TypedFML32, TypedFML

public interface FML

This is the FML interface. Both FML16 and FML32 implement this interface, and hence both types of buffer can be treated identically by applications.

  Returns:
    The following field types:
    - FLD_SHORT

              throws Ferror

  Adds the given object, whose field id is contained in key to the fielded buffer. key also contains the occurance number of the field to add to the buffer. If an entry of that field id and occurance exists in the buffer, this object will take its place. If there are no occurance numbers prior to this occurance number and field id then the occurances prior to this one will be filled in with null entries. The following table gives the Field type and the associated object expected by FML
  - FLD_SHORT - Short
  - FLD_LONG - Integer
  - FLD_CHAR - Character
  - FLD_FLOAT - Float
  - FLD_DOUBLE - Double
  - FLD_STRING - String
  - FLD_CARRAY - byte[]
  - FLD_INT - Not yet supported
  - FLD_DECIMAL - Not yet supported
  - FLD_PTR - TypedBuffer
  - FLD_FML32 - TypedFML32
  - FLD_VIEW32 - Not yet supported

  Parameters:
    `key` - The fieldid and occurance to add to the buffer
    `value` - The element to add to the buffer. Note that this object must match the type of object expected by the field type, or an invalid cast exception will be thrown
  Throws:
    Ferror - usually if space is low
  See Also:
    `FmlKey`

### Fchg

    public void Fchg(int fldid,
                     int occurance,
                     java.lang.Object value)
              throws Ferror

  Adds the given object. This version of Fchg takes the fieldid and occurance number, and may be more conveinient than the other version of Fchg which requires an FmlKey to be constructed by the caller. If an entry of that field id and occurance exists in the buffer, this object will take its place. If there are no occurance numbers prior to this occurance number and field id then the occurances prior to this one will be filled in with null entries. The following table gives the Field type and the associated object expected by FML
  - FLD_SHORT - Short
  - FLD_LONG - Integer

  - FLD_DECIMAL - Not yet supported
  - FLD_PTR - TypedBuffer
  - FLD_FML32 - TypedFML32
  - FLD_VIEW32 - Not yet supported

  Parameters:
    `fldid` - The fieldid to add to this buffer
    `occurance` - The occurance number of the field to add
    `value` - The element to add to the buffer. Note that this object must match the type of object expected by the field type, or an invalid cast exception will be thrown
  Throws:
    Ferror - usually if space is low

                          throws Ferror

  Retrieves a copy of the object stored in the FML buffer of the given field id and occurance number. Notice that changing the object returned will NOT change the value in the FML buffer. The value returned is a COPY of the value in the FML buffer. The following table gives the Field type and the associated object returned by FML
  - FLD_SHORT - Short
  - FLD_LONG - Integer
  - FLD_CHAR - Character
  - FLD_FLOAT - Float
  - FLD_DOUBLE - Double
  - FLD_STRING - String
  - FLD_CARRAY - byte[]
  - FLD_INT - Not yet supported
  - FLD_DECIMAL - Not yet supported
  - FLD_PTR - TypedBuffer
  - FLD_FML32 - TypedFML32
  - FLD_VIEW32 - Not yet supported

  Parameters:
    `key` - the field id and occurance number of the element to retrieve
  Returns:
    the field object stored at that occurance number
  Throws:
    Ferror - if the object is not found in the buffer among other reasons

### Fget

    public java.lang.Object Fget(int fldid,
                                 int occurance)
                          throws Ferror

  Retrieves a copy of the object stored in the FML buffer of the given field id and occurance number. This version of the API takes the fieldid and occurance number rather than the FmlKey Notice that changing the object returned will NOT change the value in the FML buffer. The value returned is a COPY of the value in the FML buffer. The following table gives the Field type and the associated object returned by FML
  - FLD_SHORT - Short
  - FLD_LONG - Integer
  - FLD_CHAR - Character
  - FLD_FLOAT - Float
  - FLD_DOUBLE - Double

  - FLD_DECIMAL - Not yet supported
  - FLD_PTR - TypedBuffer
  - FLD_FML32 - TypedFML32
  - FLD_VIEW32 - Not yet supported

  Parameters:
    `fldid` - The field id of the element to retrieve
    `occurance` - The occurance number of the element to retrieve
  Returns:
    the field object stored at that occurance number
  Throws:
    Ferror - if the object is not found in the buffer among other reasons

                                 throws Ferror

  Returns an iterator for the start of the fielded FML buffer. This is a replacement for the Fnext functionality in Tuxedo API. An example usage may be as follows. fmliter = fmlobj.Fiterator(); while(fmliter.hasNext()) { entry = (Map.Entry)fmliter.next(); fmlkey = (FmlKey) entry.getKey(); switch(Fldtype(fmlkey.get_fldid())) { case FLD_SHORT: value_short = (Short) entry.getValue(); } }

  Returns:
    the Iterator for the fielded FML buffer

### Foccur

    public int Foccur(int fldid)

  Parameters:
    `fldid` - the field id to look for in the fielded FML buffer
  Returns:
    the number of occurences of a fldid in the fielded FML buffer

### Fdel

    public void Fdel(FmlKey key)
              throws Ferror

  Delete given key from fielded buffer. The object with the given field id and the given occurance will be removed from the buffer

  Parameters:
    `key` - The field id and occurance of the element to be removed
  Throws:
    Ferror - if the element is not in the buffer among other reasons

                     int occurance)
              throws Ferror

    `occurance` - The occurance of the element to be removed
  Throws:
    Ferror - if the element is not in the buffer among other reasons

    public java.lang.String Fname(int fldid)
                           throws Ferror

  Returns the string that matches the given fieldid. For this mapping a list of FldTbl objects should be loaded into this FML object.

  Parameters:

    The name of the fiels
  Throws:
    Ferror - if the name cannot be found

### Fldid

    public int Fldid(java.lang.String name)
              throws Ferror

    The `integer` field id
  Throws:
    Ferror - if the field id cannot be found
