Method Detail

jjtAccept

public Object jjtAccept(OrientSqlVisitor visitor,
                        Object data)

Accept the visitor.

Specified by:

jjtAccept in interface Node

Overrides:

jjtAccept in class OBooleanExpression

evaluate

public boolean evaluate(OIdentifiable currentRecord,
                        OCommandContext ctx)

Specified by:

evaluate in class OBooleanExpression

toString

public void toString(Map<Object,Object> params,
                     StringBuilder builder)

Overrides:

toString in class SimpleNode

supportsBasicCalculation

protected boolean supportsBasicCalculation()

Specified by:

supportsBasicCalculation in class OBooleanExpression

Returns:

true if this expression can be calculated in plain Java, false otherwise (eg. LUCENE operator)

getNumberOfExternalCalculations

protected int getNumberOfExternalCalculations()

Specified by:

getNumberOfExternalCalculations in class OBooleanExpression

Returns:

the number of sub-expressions that have to be calculated using an external engine (eg. LUCENE)

getExternalCalculationConditions

Specified by:

getExternalCalculationConditions in class OBooleanExpression

Returns:

the sub-expressions that have to be calculated using an external engine (eg. LUCENE)
