Method Detail

makeSYSSTATEMENTSrow

public ExecRow makeSYSSTATEMENTSrow(boolean compileMe,
                                    SPSDescriptor spsDescriptor)
                             throws StandardException

Make a SYSSTATEMENTS row.

WARNING: When empty row is true, this method takes a snapshot of the SPSD and creates a row. It is imperative that that row remain consistent with the descriptor (the valid and StorablePreparedStatement fields must be in sync). If this row is to be written out and valid is true, then this call and the insert should be synchronized on the SPSD. This method has NO synchronization.

Parameters:

compileMe - passed into SPSDescriptorImpl.getPreparedStatement(). if true, we (re)compile the stmt

spsDescriptor - In-memory tuple to be converted to a disk row.

Returns:

Row suitable for inserting into SYSSTATEMENTS.

Throws:

StandardException - thrown on failure

buildDescriptor

public TupleDescriptor buildDescriptor(ExecRow row,
                                       TupleDescriptor parentTupleDescriptor,
                                       DataDictionary dd)
                                throws StandardException

Make an Tuple Descriptor out of a SYSSTATEMENTS row

Specified by:

buildDescriptor in class CatalogRowFactory

Parameters:

row - a SYSSTATEMENTS row

parentTupleDescriptor - unused

dd - dataDictionary

Returns:

a descriptor equivalent to a SYSSTATEMENTS row

Throws:

StandardException - thrown on failure

makeEmptyRow

public ExecRow makeEmptyRow()
                     throws StandardException

Description copied from class: CatalogRowFactory

Return an empty row for this conglomerate.

Overrides:

makeEmptyRow in class CatalogRowFactory

Throws:

StandardException

buildColumnList

public SystemColumn[] buildColumnList()
                               throws StandardException

Builds a list of columns suitable for creating this Catalog. The last column, the serialized statement, is not added to the column list. This is done deliberately to make it a 'hidden' column -- one that is not visible to customers, but is visible to the system.

Specified by:

buildColumnList in class CatalogRowFactory

Returns:

array of SystemColumn suitable for making this catalog.

Throws:

StandardException

getCreateHeapProperties

public java.util.Properties getCreateHeapProperties()

Get the Properties associated with creating the heap.

Overrides:

getCreateHeapProperties in class CatalogRowFactory

Returns:

The Properties associated with creating the heap.
