Keyword value representing a table.
Internal
TableKeyword represents a record keyword field containing a table. It is used by class TableRecord, which in its turn is meant to be used by the Table class. It serves the following purposes:
This class provides the extra functionality for keywords containing tables. This is needed because tables are much more complex entities than scalars or arrays.
// Store a table in the keyword set. void someFunc (const Table& subTable) { // Open the table and get access to the table keyword set. Table table("table.data", Table::Update); TableRecord& keyset = table.rwKeywordSet(); keyset.defineTable ("KeyTab", subTable); } // Open the table and get the table from keyword KeyTab. // It shows that this can be done in one statement. Table table("table.data"); Table subTab = table.keywordSet().asTable ("KeyTab");

casa::TableKeyword::TableKeyword | ( | const String & | tableDescName | ) |
Construct a TableKeyword with the given tableDescName.
When the tableDescName is empty the keyword is variable structured. Otherwise it is fixed structured, meaning that only tables with a description of that name can be assigned to this keyword.
Construct a TableKeyword from a Table.
When the tableDescName is empty the keyword is variable structured. Otherwise it is fixed structured, meaning that only tables with a description of that name can be assigned to this keyword.
casa::TableKeyword::TableKeyword | ( | const TableKeyword & | that | ) |
Copy constructor (full copy semantics).
casa::TableKeyword::~TableKeyword | ( | ) |
void casa::TableKeyword::close | ( | ) | const |
Close the table.
Bool casa::TableKeyword::conform | ( | const TableKeyword & | that | ) | const |
Test if the table in other conforms this table keyword.
It conforms when this description name is blank or matches the table description name of the other.
void casa::TableKeyword::flush | ( | Bool | fsync | ) | const |
Flush and optionally fsync the table.
Bool casa::TableKeyword::isFixed | ( | ) | const [inline] |
Has the table a fixed description name? It has when its description name is not empty.
Definition at line 218 of file TableKeyword.h.
Is the table in use in another process? If checkSubTables
is set, it is also checked if a subtable is used in another process.
TableKeyword& casa::TableKeyword::operator= | ( | const TableKeyword & | that | ) |
Assignment (leaves tableDescName_p untouched).
This is only possible when both objects conform.
TableKeyword& casa::TableKeyword::operator= | ( | const Table & | table | ) |
Rename the table if its path contains the old parent table name.
Set the name of the table and the writable switch.
This is used when reading back a keyword.
void casa::TableKeyword::setRW | ( | ) |
Set the keyword to read/write access.
If the table is already open, it will be reopened with read/write access if the table is writable.
void casa::TableKeyword::setTableAttributes | ( | const TableAttr & | attr | ) | [inline] |
Table casa::TableKeyword::table | ( | ) | const |
Get the table.
It will be opened when necessary.
const TableAttr& casa::TableKeyword::tableAttributes | ( | ) | const [inline] |
Definition at line 167 of file TableKeyword.h.
Get the name of the table relative to parent table.
const String & casa::TableKeyword::tableName | ( | ) | const [inline] |
Get the name of the table.
