public class RegExConstraint

extends Constraint

A constraint that specifies a regular expression pattern for a Parameter's values.

e.g. "ab"

NOTE: To use this type of constraint, your driver MUST run in a 1.4 JVM or later.

Constructor Summary

RegExConstraint(String somePattern)
Creates a new regular expression constraint using the specified pattern and pattern flags.

RegExConstraint(String somePattern, int flags)
Creates a new regular expression constraint using the specified pattern and pattern flags.

RegExConstraint

public RegExConstraint(String somePattern,
                       int flags)

Creates a new regular expression constraint using the specified pattern and pattern flags.

Parameters:

somePattern - a legal regular expression pattern; must not be null

flags - should be one of the integer constants specified in class java.util.regex.Pattern

Throws:

IllegalArgumentException - if pattern is null or an illegal pattern

See Also:

Pattern

RegExConstraint

public RegExConstraint(String somePattern)

Creates a new regular expression constraint using the specified pattern and pattern flags.

Parameters:

somePattern - a legal regular expression pattern; must not be null

Throws:

IllegalArgumentException - if pattern is null or an illegal pattern

See Also:

Pattern

Method Detail

hashCode

public int hashCode()

Returns this constraint's hashcode.

Returns:

the hashcode

equals

public boolean equals(Object o)

Is the passed constraint equal to this constraint?

Parameters:

o - may be null

Returns:

true if they're equal; false if they're not

cloneAsNeeded

public Object cloneAsNeeded(boolean sameParameter)

forStructured

public boolean forStructured()

Description copied from class: Constraint

Can this constraint be applied to a structured Parameter?

A structured Parameter consists of multiple primitives or other structured Parameters.

Specified by:

forStructured in class Constraint

Returns:

true if it can; false if it can't

forScalar

public boolean forScalar()

Description copied from class: Constraint

Can this constrait be applied to a scalar Parameter?

A scalar Parmeter is a primitive (e.g., long, int, boolean) that has a single value.

Specified by:

forScalar in class Constraint

Returns:

true if it can; false if it can't

canBeAppliedToMultipleParams

public boolean canBeAppliedToMultipleParams()

Description copied from class: Constraint

Can this constraint be applied to multiple Parameters?

Specified by:

canBeAppliedToMultipleParams in class Constraint

Returns:

true if it can; false if it can't
