Function Documentation

const_accessor clone ( ) const [inherited]

This function allocates a new object on the heap and copies the contents of the current object to the new object.
Returns:
an accessor to the new object.

Note:
Call const_accessor::destroy when you no longer need the clone.

Reimplemented in accessor.

accessor const_cast_accessor ( const const_accessor & access )

Removes the const'ness. Similar to const_cast<>.

accessor create_object ( prop_t object_type )

void destroy_object ( accessor & a )

typed_const_accessor<Value> dynamic_cast_accessor ( const const_accessor & p )

typed_accessor<Value> dynamic_cast_accessor ( const accessor & p )

aggregate get_aggregate ( ) const [inherited]

Reimplemented from const_accessor.

const_aggregate get_aggregate ( ) const [inherited]

It is valid to call get_aggregate for an object that isn't an aggregate. If thats the case, const_aggregate::is_valid() will return false for the returned aggregate accessor.
Reimplemented in accessor.

bool is_type ( const const_accessor & p )

Returns:
true if the object is of type Value. is_type<int>(p) will return true if p is an accessor for an int object. Likewise is_type<string>(p) returns true if p is an accessor for a string object.

accessor make_accessor ( Value & v )

Returns:
an accessor pointing to the object passed as parameter v. accessor objects can read and write objects they point to.

Note:
This creates a pointer to the object. The object itself is not modified in any way. Its lifetime must be longer than the lifetime of the accessor.

aggregate make_aggregate ( Value & v )

const_accessor make_const_accessor ( const Value & v )

Returns:
a const_accessor pointing to the object passed as parameter v. const_accessor object can read, but not write the object they point to.

Note:
This creates a pointer to the object. The object itself is not modified in any way. Its lifetime must be longer than the lifetime of the accessor.

const_aggregate make_const_aggregate ( Value & v )
