Field Detail

TYPE_UNDEFINED

public static final int TYPE_UNDEFINED

This is used only when constraint is first created. This means that there is no value yet for the constraint.

TYPE_LITERAL

public static final int TYPE_LITERAL

This may be string, or number, anything really.

See Also:: Constant Field Values

TYPE_VARIABLE

public static final int TYPE_VARIABLE

This is when it is set to a valid previously bound variable.

See Also:: Constant Field Values

TYPE_RET_VALUE

public static final int TYPE_RET_VALUE

This is for a "formula" that calculates a value.

See Also:: Constant Field Values

TYPE_ENUM

public static final int TYPE_ENUM

This is not used yet. ENUMs are not suitable for business rules until we can get data driven non code enums.

TYPE_PREDICATE

public static final int TYPE_PREDICATE

The fieldName and fieldBinding is not used in the case of a predicate.
