FML (Java API Reference for Oracle WebLogic Server)

All Known Implementing Classes:

TypedFML, TypedFML32
```
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.

FmlKey, FldTbl, mkfldclass

    Returns:
    The following field types:
    
    FLD_SHORT
    FLD_LONG
    FLD_CHAR
    FLD_FLOAT
    FLD_DOUBLE

void Fchg(FmlKey key,

   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_DECIMAL - Not yet supported
    - FLD_PTR - TypedBuffer

    - 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

```
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_CHAR - Character

    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

```
java.lang.Object Fget(FmlKey key)
               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

    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
```
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_STRING - String

    - 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

  - Fiterator
```
java.util.Iterator Fiterator()
                      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
    
    Throws:
    
    Ferror
  - Foccur
```
int Foccur(int fldid)
```
    Returns the number of occurences of the field specified by 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
```
void Fdel(FmlKey key)

    Throws:
    
    Ferror - if the element is not in the buffer among other reasons

          int occurance)
   throws Ferror
```
    Delete given element from fielded buffer. The object with the given field id and the given occurance will be removed from the buffer. This differs from the other version in that it takes the field id and occurance number rather than a constructed key
    
    Parameters:
    
    fldid - The field id of the element to be removed
    
    occurance - The occurance of the element to be removed

    Returns:
    
    The name of the fiels

    Parameters:
    
    name - the name of the field we are trying to find
    
    Returns:
    
    The integer field id
    
    Throws:
    
    Ferror - if the field id cannot be found
