Supported data types

The Managed Adapter Configuration and Mapping Framework supports two-way conversion between various Target types and Source types, as listed in the following table.

Supported data types for conversion

Table 5. Supported data types for conversion
Source data type	Target data type	java.lang.String	java.lang.Long	java.lang.Integer	java.lang.Double	java.lang.Float	java.lang.BigDecimal	java.lang.Timestamp	java.lang.Boolean	java.lang.Object
java.lang.String		S	SF	SF	SF	SF	SF	SF	SF	S
java.lang.Long		SC	S	SC	SC	SC	SC	SC	SC	S
java.lang.Integer		SC	SC	S	SC	SC	SC	SC	SC	S
java.lang.Double		SC	SC	SC	S	SC	SC	SC	SC	S

S: supported, no conversion performed

SF: supported, if the source is in proper format

SC: supported, conversion performed

NS: not supported

Rules

When a value is converted from one data type to another, the following rules apply:

Converting numeric values. Some care must be exercised when converting between different numeric types. The transformation may involve loss of precision or the value may be truncated. For example, if an adapter output is defined as java.lang.Double, you may still map it to an integer data type, but in this case the value will be rounded off.

Note: All numeric types except "BigDecimal" are internally stored as "Double" values, which can have an effect when trying to convert values outside the range of the target type.

Converting between boolean and numeric types. When a number is converted to Boolean, any non-negative value will be converted to "true"; negative or zero value will be converted to "false". The reverse conversion, from boolean to numeric, maps "true" to "1" and "false" to "0".

Mapping to "java.lang.Object". If any value is mapped to "java.lang.Object", no transformation will be performed.

Mapping <null> values.When a mapped input dataslot contains a null value, the corresponding input will not be defined in the adapter inputs hashtable. When a Managed Adapter returns a null value for a mapped output, the value of the corresponding dataslot will be set to the dataslot default value by BP Server.
