                                     throws dap4.core.util.DapException

It is common to want to parse a DMR text to a DapDataset, so provide this utility.

Parameters:

document - the dmr to parse

Returns:

the parsed dmr

Throws:

dap4.core.util.DapException - on parse errors

processAttributes

protected void processAttributes(dap4.core.dmr.DapDataset dataset)
                          throws dap4.core.util.DapException

Walk the dataset tree and remove selected attributes such as _Unsigned

Parameters:

dataset -

Throws:

dap4.core.util.DapException

suppress

protected boolean suppress(java.lang.String attrname)

Some attributes that are added by the NetcdfDataset need to be kept out of the DMR. This function defines that set.

Parameters:

attrname - A non-escaped attribute name to be tested for suppression

Returns:

true if the attribute should be suppressed, false otherwise.
