Class DependentSetCriteria

java.lang.Object

org.teiid.query.sql.lang.Criteria

org.teiid.query.sql.lang.PredicateCriteria

org.teiid.query.sql.lang.AbstractSetCriteria

org.teiid.query.sql.lang.DependentSetCriteria

All Implemented Interfaces:

Cloneable, PredicateCriteria.Negatable, LanguageObject, ContextReference, Expression

public class DependentSetCriteria
extends AbstractSetCriteria
implements ContextReference

The DependentSetCriteria is missing the value set until it is filled during processing. This allows a criteria to contain a dynamic set of values provided by a separate processing node.

Since:

5.0.1

Constructor Detail

DependentSetCriteria

public DependentSetCriteria(Expression expr,
                            String id)

Construct with the left expression

Method Detail

setAttributes

public void setAttributes(List<DependentSetCriteria.AttributeComparison> attributes)

getAttributes

public List<DependentSetCriteria.AttributeComparison> getAttributes()

There is a mismatch between the expression form and the more convenient attribute comparison, so we reconstruct when needed

hasMultipleAttributes

public boolean hasMultipleAttributes()

getContextSymbol

public String getContextSymbol()

Specified by:

getContextSymbol in interface ContextReference

getMaxNdv

public float getMaxNdv()

setMaxNdv

public void setMaxNdv(float maxNdv)

getNdv

public float getNdv()

setNdv

public void setNdv(float ndv)

getValueExpression

public Expression getValueExpression()

Get the independent value expression

Returns:

Returns the valueExpression.

setValueExpression

public void setValueExpression(Expression valueExpression)

Set the independent value expression

Parameters:

valueExpression - The valueExpression to set.

acceptVisitor

public void acceptVisitor(LanguageVisitor visitor)

Description copied from interface: LanguageObject

Method for accepting a visitor. It is the responsibility of the language object to call back on the visitor.

Specified by:

acceptVisitor in interface LanguageObject

Parameters:

visitor - Visitor being used

hashCode

public int hashCode()

Get hash code. WARNING: The hash code is based on data in the criteria. If data values are changed, the hash code will change - don't hash this object and change values.

Overrides:

hashCode in class Object

Returns:

Hash code

equals

public boolean equals(Object obj)

Override equals() method.

Overrides:

equals in class Object

Parameters:

obj - Other object

Returns:

True if equal

clone

public DependentSetCriteria clone()

Deep copy of object. The values iterator source of this object will not be cloned - it will be passed over as is and shared with the original object, just like Reference.

Specified by:

clone in interface LanguageObject

Specified by:

clone in class AbstractSetCriteria

Returns:

Deep copy of object

setNegated

public void setNegated(boolean negationFlag)

Description copied from class: AbstractSetCriteria

Sets the negation flag for this criteria.

Overrides:

setNegated in class AbstractSetCriteria

Parameters:

negationFlag - true if this criteria contains a NOT; false otherwise

getDependentValueSource

public DependentValueSource getDependentValueSource()

setDependentValueSource

public void setDependentValueSource(DependentValueSource dependentValueSource)

setMakeDepOptions

public void setMakeDepOptions(Option.MakeDep makeDep)

getMakeDepOptions

public Option.MakeDep getMakeDepOptions()
