| Class | Description |
|---|---|
| AttributeEntry |
Represents an entry in a global or variable attribute.
|
| CdfContent |
Provides all the data and metadata in a CDF file in a high-level
read-only easy to use form.
|
| CdfInfo |
Encapsulates some global information about a CDF file.
|
| CdfReader |
Examines a CDF file and provides methods to access its records.
|
| DataType |
Enumerates the data types supported by the CDF format.
|
| EpochFormatter |
Does string formatting of epoch values in various representations.
|
| GlobalAttribute |
Provides the description and entry values
for CDF attribute with global scope.
|
| Shaper |
Takes care of turning raw variable record values into shaped
record values.
|
| TtScaler |
Handles conversions between TT_TIME2000 (TT since J2000.0)
and Unix (UTC since 1970-01-01) times.
|
| Variable |
Provides the metadata and record data for a CDF variable.
|
| VariableAttribute |
Provides the description and per-variable entry values
for a CDF attribute with variable scope.
|
| Exception | Description |
|---|---|
| CdfFormatException |
Exception thrown during CDF parsing when the data stream appears either
to be in contravention of the CDF format, or uses some feature of
the CDF format which is unsupported by the current implementation.
|
For low-level access to the record data of a CDF file, use the
CdfReader class.
For high-level access to the variables and attributes that form
the CDF data and metadata, use the
CdfContent class.
The package makes extensive use of NIO buffers for mapped read-on-demand data access, so should be fairly efficient for reading scalar records and whole raw array records. Convenience methods for reading shaped arrays may be less efficient.
This package is less capable than the official JNI-based java interface to the CDF C library (read only, less flexible data read capabilities), but it is pure java (no native code required) and it's also quite a bit less complicated to use.
