Constructor Detail

LikeConstraint

public LikeConstraint(DynamicOperand operand1,
                      Value operand2,
                      org.apache.jackrabbit.spi.commons.query.qom.SelectorImpl selector)
               throws RepositoryException

Creates a new like constraint.

Parameters:

operand1 - the dynamic operand.

operand2 - the static operand.

selector - the selector for the dynamic operand.

Throws:

RepositoryException - if an error occurs reading the string value from the static operand.

Method Detail

evaluate

protected boolean evaluate(Value op1)
                    throws RepositoryException

Evaluates this constraint for the given dynamic operand value op1.

Overrides:

evaluate in class ComparisonConstraint

Parameters:

op1 - the current value of the dynamic operand.

Returns:

true if the given value satisfies the constraint.

Throws:

RepositoryException - if an error occurs while converting the values.
