Class TypedFML32

java.lang.Object
  weblogic.wtc.jatmi.StandardTypes
      weblogic.wtc.jatmi.MBStringTypes
          weblogic.wtc.jatmi.TypedFML32

All Implemented Interfaces:

Serializable, FML, TypedBuffer

public final class TypedFML32

extends MBStringTypes

implements TypedBuffer, Serializable, FML

This implements TypedFML32 in JAVA as a TypedBuffer. Fieldids are generated with the tool mkfldclass32, and then put into the buffer with the appropriate TypedFML32 methods. Note that in this implementation Fieldids must be combined into a field key, which is a combination of the Fldid32 and the occurrence number. Any number of field tables can be loaded into any TypedFML32 object in order to do FldId to String conversions and String to FldId conversions.

The field number associated with this feild id

Fldtype

public int Fldtype(int fldid32)

Given a fieldid, this returns the field type

Specified by:

Fldtype in interface FML

Parameters:

fldid32 - The field id from which to extract the field type

Returns:

The following field types:

Fchg

public 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 occurrence number of the field to add to the buffer. If an entry of that field id and occurrence exists in the buffer, this object will take its place. If there are no occurrence numbers prior to this occurrence number and field id then the occurrences 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 - FviewFld
• FLD_MBSTRING - TypedMBString

Specified by:

Fchg in interface FML

Parameters:

key - The fieldid and occurrence 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

public void Fchg(int fldid,
                 int occurrence,
                 Object value)
          throws Ferror

Adds the given object. This version of Fchg takes the fieldid and occurrence number, and may be more conveinient than the other version of Fchg which requires an FmlKey to be constructed by the caller.
