                                                   RuntimeMetadata metadata,
                                                   ObjectConnection connection)
                                            throws TranslatorException

Overrides:

supportsCompareCriteriaEquals

public boolean supportsCompareCriteriaEquals()

Description copied from class: ExecutionFactory

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

Overrides:

supportsCompareCriteriaEquals in class ExecutionFactory<javax.resource.cci.ConnectionFactory,ObjectConnection>

supportsInCriteria

public boolean supportsInCriteria()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element IN set)

Overrides:

supportsOnlyLiteralComparison

public boolean supportsOnlyLiteralComparison()

Overrides:

supportsOnlyLiteralComparison in class ExecutionFactory<javax.resource.cci.ConnectionFactory,ObjectConnection>

Returns:

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

setSearchType

public void setSearchType(SearchType type)

getSearchType

public SearchType getSearchType()

getMetadataProcessor

public MetadataProcessor<ObjectConnection> 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<javax.resource.cci.ConnectionFactory,ObjectConnection>

Returns:

search

public List<Object> search(ObjectSelectVisitor visitor,
                           ObjectConnection connection,

Throws:

TranslatorException

performKeySearch

public Object performKeySearch(String columnName,
                               Object value,
                               ObjectConnection connection,
                               ExecutionContext executionContext)
                        throws TranslatorException

The searchByKey is used by update operations that need to obtain a specific object, but don't need to create a Select command in order to find a single object.

Parameters:

columnName -

value -

connection -

executionContext -

Returns:

Object

Throws:

TranslatorException

supportsRowLimit

public boolean supportsRowLimit()
