InvCatalogImpl

public InvCatalogImpl(java.lang.String name,
                      java.lang.String version,
                      DateType expires,
                      java.net.URI baseURI)

Construct an InvCatalog. You must call finish() after all objects are added.

Parameters:

name - : catalog name.

version - : catalog version.

expires - : date/time catalog expires.

baseURI - : catalog base URI (external).

Method Detail

subset

public void subset(InvDataset ds)

Deprecated. in favor of thredds.catalog.util.DeepCopyUtils.subsetCatalogOnDataset

Munge this catalog so the given dataset is the top catalog.

Specified by:

subset in class InvCatalog

Parameters:

ds - make this top; must be existing dataset in this catalog.

filter

public void filter(DatasetFilter filter)

Munge this catalog to remove any dataset that doesnt pass through the filter.

Specified by:

filter in class InvCatalog

Parameters:

filter - remove datasets that dont pass this filter.

getDatasetFilter

protected DatasetFilter getDatasetFilter()

finish

public boolean finish()

Finish constructing after all elements have been added or modified. This routine will do any needed internal consistency work. Its ok to call multiple times.

Returns:

true if successful.

addDatasetByID

public void addDatasetByID(InvDatasetImpl ds)

Add Dataset to internal hash.

Parameters:

ds - : add this dataset if ds.getID() != null

See Also:

InvCatalog.findDatasetByID(java.lang.String)

removeDatasetByID

public void removeDatasetByID(InvDatasetImpl ds)

Find the dataset in this catalog by its ID. If found, remove it.

Parameters:

ds - Remove this dataset from the hash

addDataset

public void addDataset(InvDatasetImpl ds)

Add Dataset (1.0)

Parameters:

ds - add this dataset

removeDataset

public boolean removeDataset(InvDatasetImpl ds)

Remove the given dataset from this catalog if it is a direct child of this catalog.

Parameters:

ds - remove this dataset

Returns:

true if found and removed

replaceDataset

public boolean replaceDataset(InvDatasetImpl remove,
                              InvDatasetImpl add)

Replace the given dataset if it is a nested dataset.

Parameters:

remove - - the dataset element to be removed

add - - the dataset element to be added

Returns:

true on success

addProperty

public void addProperty(InvProperty p)

Add Property (1.0)

Parameters:

p - add this property

addService

public void addService(InvService s)

Add Service (1.0)

Parameters:

s - add this service

setDataset

public void setDataset(InvDatasetImpl ds)

Deprecated. Use addDataset() instead; datamodel now allows multiple top level datasets.

Add top-level InvDataset to this catalog.
