boost::shared_ptr< PeakTable > lsst.afw.detection::PeakTable::make ( afw::table::Schema const &  schema, bool  forceNew = false  )

static

Obtain a table that can be used to create records with given schema.

Parameters

[in]	schema	Schema that defines the fields, offsets, and record size for the table.
[in]	forceNew	If true, guarantee that the returned PeakTable will be a new one, rather than attempting to reuse an existing PeakTable with the same Schema.

If a PeakTable already exists that uses this Schema, that PeakTable will be returned instead of creating a new one. This is different from how most Record/Table classes work, but it is an important memory optimization for Peaks, for which we expect to have very few distinct Schemas as well as many catalogs (one per Footprint) with a small number of Peaks; we don't want to have a different PeakTable for each one of those catalogs if they all share the same Schema. This behavior can be disabled by setting forceNewTable=true or by cloning an existing table (in both of these cases, the new table will not be reused in the future, either)
