Interface FML

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.

See Also:

FldTbl

getFieldTables

FldTbl[] getFieldTables()

gets the current list of FldTbls that are being used by this TypedFML object to do FldId/String mappings.

Returns:

The list of FldTbl objects used for FldId/String mappings

Fldno

int Fldno(int fldid)

Given a fieldid, this returns the field number

Parameters:

fldid - The field id from which to extract the field number

Returns:

The field number associated with this feild id

Fldtype

int Fldtype(int fldid)

Given a fieldid, this returns the field type

Parameters:

fldid - The field id from which to extract the field type

Returns:

The following field types:

• FLD_SHORT

Fchg

void Fchg(FmlKey key,
          Object value)
          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

FmlKey

Fchg

void Fchg(int fldid,
          int occurance,
          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
• 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:

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

FmlKey

Fget

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
• 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

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_CARRAY - byte[]
• FLD_INT - Not yet supported
• 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

Fiterator

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

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

Fdel

void Fdel(int fldid,
          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

Throws:

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

Fname

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:

fldid - The field id to map to a string

Returns:

The name of the fiels

Throws:

Ferror - if the name cannot be found

Fldid

int Fldid(String name)
          throws Ferror

Returns the field id corresponding to the given name. A table of FldTbl objects should be loaded into this FML object in order to map the name to a field id.

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

Fused

int Fused()
          throws Ferror
