T* ugrid::extractArray ( libdap::Array * a )

Given a pointer to an Array that holds a numeric type, extract the values and return in an array of T.

This function allocates the array using 'new T[n]' so delete[] can be used when you are done the data.

Definition at line 98 of file ugrid_utils.h.

GF::Array * ugrid::extractGridFieldArray	(	libdap::Array *	a,
		vector< int * > *	sharedIntArrays,
		vector< float * > *	sharedFloatArrays
	)

Extract data from a DAP array and return those values in a gridfields array.

This function sets the send_p property of the DAP Array and uses its read() member function to get values. Thus, it should work for values stored in any type of data source (e.g., file) for which the Array class has been specialized.

Parameters

a	The DAP Array. Extract values from this array

Returns: A GF::Array

int ugrid::getNfrom3byNArray ( libdap::Array * array )

Retrieves the size of the second dimension from a 3xN array.

Throws an Error if the array is not the correct shape.

bool ugrid::matchesCfRoleOrStandardName	(	BaseType *	bt,

	)

Checks the passed BaseType attributes as follows: If the BaseType has a "cf_role" attribute and it's value is the same as aValue return true.

If it doesn't have a "cf_role" attribute, then if there is a "standard_name" attribute and it's value is the same as aValue then return true. All other outcomes return false.

vector< string > & ugrid::split	(	const string &	s,

Splits the string on the passed char.

Returns vector of substrings. TODO make this work on situations where multiple spaces doesn't hose the split()

vector< string > ugrid::split	(	const string &	s,

void ugrid::ugr5	(	int	argc,
		BaseType *	argv[],
		DDS &	dds,
		BaseType **	btpp
	)

Subset an irregular mesh (aka unstructured grid).

Parameters

argc	Count of the function's arguments
argv	Array of pointers to the functions arguments
dds	Reference to the DDS object for the complete dataset. This holds pointers to all of the variables and attributes in the dataset.
btpp	Return the function result in an instance of BaseType referenced by this pointer to a pointer. We could have used a BaseType reference, instead of pointer to a pointer, but we didn't. This is a value-result parameter.

Returns: void

Exceptions

Error Thrown If the Array is not a one dimensional array.

Here is where we will do the range variable sub-setting including decomposing the requested variable into 1-dimensional hyper-slabs that can be fed into the gridfields library
