Detailed Description

An AttrTable (``Attribute Table'') stores a set of names and, for each name, either a type and a value, or another attribute table. The attribute value can be a vector containing many values of the same type. The attributes can have any of the types listed in the AttrType list. However, all attribute types are stored as string data, except for the container type, which is stored as a pointer to another attribute table.

Each element in the attribute table can itself be an attribute table. The table can also contain ``alias'' attributes whose value is given by the value of another attribute to which it is linked.

The attribute tables have a standard printed representation. There is a member function print() for writing this form. Use the DAS::parse() function to read the printed form.

An attribute table might look something like this:

string long_name "Weekly Means of Sea Surface Temperature";
actual_range {
    Float64 min -1.8;
    Float64 max 35.09;
}
string units "degC";
conversion_data {
    Float64 add_offset 0.;
    Float64 scale_factor 0.0099999998;
}
Int32 missing_value 32767;

Here, long_name, units, and missing_value are simple attributes, and actual_range and conversion_data are container attributes containing other attribute tables.

Todo:
Look at refactoring this by splitting it into three classes. Move the struct entry into its own calls (maybe called Attribute?), make AttrTable a child of that class and then make aliases a separate class, also a child of Attribute. Look at the design of the Java code.
Todo:
A problem with this class is that Attr_iter objects cannot be dereferenced to return attributes. Instead they must be passed to methods which require that you have access to the AttrTable object into which they point.03/09/04 jhrg

unsigned int libdap::AttrTable::append_attr ( const string &  name,
const string &  type,
const string &  attribute 
)
virtual

If the given name already refers to an attribute, and the attribute has a value, the given value is appended to the attribute vector. Calling this function repeatedly is the way to append to an attribute vector.

The function throws an Error if the attribute is a container, or if the type of the input value does not match the existing attribute's type. Use append_container() to add container attributes.

This method performs a simple search for name in this attribute table only; sub-tables are not searched and the dot notation is not recognized.

Returns
Returns the length of the added attribute value.
Parameters
nameThe name of the attribute to add or modify.
typeThe type of the attribute to add or modify.
attributeThe value to add to the attribute table.

This version of append_attr() takes a vector<string> of values. If the given name already refers to an attribute, and the attribute has values, append the new values to the existing ones.

The function throws an Error if the attribute is a container, or if the type of the input value does not match the existing attribute's type. Use append_container() to add container attributes.

This method performs a simple search for name in this attribute table only; sub-tables are not searched and the dot notation is not recognized.

Returns
Returns the length of the added attribute value.
Parameters
nameThe name of the attribute to add or modify.
typeThe type of the attribute to add or modify.
valuesA vector of values. Note: The vector is COPIED, not stored.

bool libdap::AttrTable::attr_alias ( const string &  alias,
AttrTable at,
const string &  name

virtual

Once an alias is inserted into an attribute table, reading the attributes for alias will return those stored for name.

Two forms for this function exist: one searches for name in the AttrTable referenced by at while the other uses this. You can use DAS::get_attr_table() to get the attribute table for an arbitrary name.

Delete the attribute named name. If i is given, and the attribute has a vector value, delete the i$^th$ element of the vector.

You can use this function to delete container attributes, although the i parameter has no meaning for that operation.

Parameters
nameThe name of the attribute to delete. This can be an attribute of any type, including containers. However, this method looks only in this attribute table and does not recognize the dot notation.
iIf the named attribute is a vector, and i is non-negative, the i-th entry in the vector is deleted, and the array is repacked. If i equals -1 (the default), the entire attribute is deleted.

void libdap::AttrTable::find ( const string &  target,

Look for an attribute or an attribute container. If used to search for an attribute container, this method returns the container's parent using the value-result parameter at and a reference to the container using the iterator value-result parameter iter. If used to search for an attribute, the attribute's container is returned using at; the attribute itself can be accessed using the iterator iter.

Parameters
targetThe name (using dot notation) of the attribute or container to find.
atA value-result used to return the attribute container in which target was found. Null if target was not found.
iterThe iterator which will reference the attribute found. Can be used to access target from within at. References dim_end() within at if the attribute or container does not exist.

string libdap::AttrTable::get_attr ( Attr_iter  iter,

Returns the value of an attribute. If the attribute has a vector value, you can indicate which is the desired value with the index argument, i. If the argument is omitted, the first value is returned. If the attribute has only a single value, the index argument is ignored. If i is greater than the number of elements in the attribute, an error is produced.

All values in an attribute table are stored as string data. They may be converted to a more appropriate internal format by the calling program.

Parameters
iterReference to an attribute
iThe attribute value index, zero-based. Default value: 0
Returns
If the indicated attribute is a container, this function returns the string ``None''. If using a name to refer to the attribute and the named attribute does not exist, return the empty string.

Here is the call graph for this function:

AttrTable * libdap::AttrTable::recurrsive_find ( const string &  target,
Attr_iter location 
)
virtual

This method scans for attributes using recursion to look inside containers even when the name of the attribute is not fully qualified. It starts looking in itself and descends into its children depth first. It will find attributes and attribute containers.

Parameters
targetLook for the attribute with this name.
locationA value-result parameter. This returns an iterator to the attribute within the returned AttrTable object
Returns
Returns a pointer to the AttrTable which holds target, or null if target is not found. In the latter case, the value of location is attr_end() for this AttrTable.

Returns
An Attr_iter which references target.
