Write a message to fp describing the error.
void dump (std::ostream &fp=ExEnv::err0())

Constructors.
These contructors create an AggregateKeyVal that is formed from several other KeyVal objects.

The search order is keyval1, keyval2, and so on. All KeyVal objects including and after the first null KeyVal will be ignored.

AggregateKeyVal (const Ref< KeyVal > &keyval1)

AggregateKeyVal (const Ref< KeyVal > &keyval1, const Ref< KeyVal > &keyval2)

AggregateKeyVal (const Ref< KeyVal > &keyval1, const Ref< KeyVal > &keyval2, const Ref< KeyVal > &keyval3)

AggregateKeyVal (const Ref< KeyVal > &keyval1, const Ref< KeyVal > &keyval2, const Ref< KeyVal > &keyval3, const Ref< KeyVal > &keyval4)

Protected Member Functions

int key_exists (const char *)
Ultimately called by exists.
Ref< KeyValValue > key_value (const char *, const KeyValValue &def)
Ultimately called by value.

Detailed Description

This takes several KeyVal objects and makes them look like one KeyVal object.

When a key is sought first KeyVal, then the next, and so on is searched until the keyword is found.
