Method Detail

createResultSetExecution

public ResultSetExecution createResultSetExecution(QueryExpression command,
                                                   ExecutionContext executionContext,
                                                   RuntimeMetadata metadata,
                                                   VirtualFileConnection connection)
                                            throws TranslatorException

Overrides:

createResultSetExecution in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

Throws:

TranslatorException

getMetadataProcessor

public MetadataProcessor<VirtualFileConnection> getMetadataProcessor()

Description copied from class: ExecutionFactory

Get a MetadataProcessor for the translator to read the metadata. Typically this will return a new instance.

Overrides:

getMetadataProcessor in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

Returns:

supportsCompareCriteriaEquals

public boolean supportsCompareCriteriaEquals()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element = constant)

Overrides:

supportsCompareCriteriaEquals in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

supportsOnlyLiteralComparison

public boolean supportsOnlyLiteralComparison()

Overrides:

supportsOnlyLiteralComparison in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

Returns:

true if only Literal comparisons (equality, ordered, like, etc.) are supported for non-join conditions.

supportsCompareCriteriaOrdered

public boolean supportsCompareCriteriaOrdered()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element <=|>= constant)
The query engine will may pushdown queries containing < or > if NOT is also supported.

Overrides:

supportsCompareCriteriaOrdered in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

supportsNotCriteria

public boolean supportsNotCriteria()

Description copied from class: ExecutionFactory

Support indicates connector accepts logical criteria NOT

Overrides:

supportsNotCriteria in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

supportsOrCriteria

public boolean supportsOrCriteria()

Description copied from class: ExecutionFactory

Support indicates connector accepts logical criteria connected by OR

Overrides:

supportsOrCriteria in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>

supportsIsNullCriteria

public boolean supportsIsNullCriteria()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element IS NULL)

Overrides:

supportsIsNullCriteria in class ExecutionFactory<ConnectionFactory,VirtualFileConnection>
