Method Detail

getDependencies

public java.util.Set getDependencies()

Description copied from interface: TempDataHandle

A set of data handle names upon which were used to generate this temporary data. The catalog module uses this to check if a result is made out-of-date by the modification of another dataset.

Specified by:

getDependencies in interface TempDataHandle

getDataHandles

public DataHandle[] getDataHandles()

Specified by:

getDataHandles in interface TempDataHandle

Returns:

Returns handles for accessing the data. Multiple handles may be returned if the data can be accessed by multiple names (for instance, via an analysis expression or using a short name), or if a single operation generated multiple data objects

getStorageSize

public long getStorageSize()

Specified by:

getStorageSize in interface TempDataHandle

Returns:

The number of bytes of storage being used by this data. This is dependent on the storage format of the data and thus does not directly indicate the number of data values being stored.

getCreateTime

public long getCreateTime()

Specified by:

getCreateTime in interface TempDataHandle

Returns:

The time at which the data was initially stored

deleteStorage

public void deleteStorage()

Description copied from interface: TempDataHandle

Deletes the temporary data.

Specified by:

deleteStorage in interface TempDataHandle
