Inheritance diagram for casa::PlainColumn:
Internal
PlainColumn represents any column in a plain table. A plain table is a regular table, i.e. not a table like a RefTable which is a view on a plain table.
Abstract base class for all types of columns in a plain table. It implements the common functionality for all columns in a plain table. Furthermore it defines some virtual functions (on top of the virtual functions defined in BaseColumn) which are specific for plain columns.

| virtual casa::PlainColumn::~PlainColumn | ( | ) | [virtual] |
| virtual Bool casa::PlainColumn::isWritable | ( | ) | const [virtual] |
Test if the column is in principle writable.
This does not test if the table itself is writable. That has to be done by the caller.
Implements casa::BaseColumn.
| virtual Bool casa::PlainColumn::isStored | ( | ) | const [virtual] |
| TableRecord& casa::PlainColumn::rwKeywordSet | ( | ) | [virtual] |
| TableRecord& casa::PlainColumn::keywordSet | ( | ) | [virtual] |
Implements casa::BaseColumn.
| uInt casa::PlainColumn::nrow | ( | ) | const [virtual] |
| virtual void casa::PlainColumn::setShapeColumn | ( | const IPosition & | shape | ) | [virtual] |
Define the shape of all arrays in the column.
| virtual Bool casa::PlainColumn::isBound | ( | ) | const [virtual] |
Test if the column is bound to a storage manager or virtual column engine.
| virtual void casa::PlainColumn::bind | ( | DataManager * | ) | [virtual] |
Bind the column to a data manager.
| virtual void casa::PlainColumn::createDataManagerColumn | ( | ) | [pure virtual] |
Create a data manager column for a filled column.
| DataManager * casa::PlainColumn::dataManager | ( | ) | const [inline] |
Get the pointer to the data manager.
Definition at line 179 of file PlainColumn.h.
References dataManPtr_p.
| DataManagerColumn *& casa::PlainColumn::dataManagerColumn | ( | ) | [inline] |
Get the pointer to the data manager column.

| virtual ColumnCache& casa::PlainColumn::columnCache | ( | ) | [virtual] |
| virtual void casa::PlainColumn::setMaximumCacheSize | ( | uInt | nbytes | ) | [virtual] |
Read the column.
| virtual void casa::PlainColumn::putFileDerived | ( | AipsIO & | ) | [protected, pure virtual] |
Write the column.
The control information is written into the given AipsIO object, while the data is written by the storage manager.
| virtual void casa::PlainColumn::getFileDerived | ( | AipsIO & | , | |
| const ColumnSet & | ||||
| ) | [protected, pure virtual] |
Read the column back.
The control information is read from the given AipsIO object. This is used to bind the column to the appropriate data manager.
| void casa::PlainColumn::checkValueLength | ( | const void * | ) | const [inline, protected] |
Check the length of a value.
This a meant for String values for which a maximum length is defined. The void* version is a no-op for other values.
Definition at line 184 of file PlainColumn.h.
| void casa::PlainColumn::checkValueLength | ( | const String * | value | ) | const [protected] |
| void casa::PlainColumn::checkReadLock | ( | Bool | wait | ) | const [inline, protected] |
Lock the table before reading or writing.
If manual or permanent locking is in effect, it checks if the table is locked.
