Constructor Detail

BasicCompareFieldsConstraint

public BasicCompareFieldsConstraint(StepField field1,
                                    StepField field2)

Constructor.

Parameters:

field2 - The second associated field.

Throws:

java.lang.IllegalArgumentException - when an invalid argument is supplied.

Method Detail

getField2

public StepField getField2()

Description copied from interface: CompareFieldsConstraint

Gets the second associated field.

Specified by:

getField2 in interface CompareFieldsConstraint

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: Constraint

Compares this constraint to the specified object. The result is true if and only if the argument is a non-null Constraint object representing the same constraint(s).

Specified by:

equals in interface Constraint

Overrides:

equals in class BasicFieldCompareConstraint

hashCode

public int hashCode()

Specified by:

hashCode in interface Constraint

Overrides:

hashCode in class BasicFieldCompareConstraint

toString

public java.lang.String toString()

Description copied from interface: CompareFieldsConstraint

Returns a string representation of this CompareFieldsConstraint. The string representation has the form "CompareFieldsConstraint(inverse:<:inverse>, field:<field>, casesensitive:<casesensitive>, operator:<operator>, field2:<field2>)" where

• <inverse>is the value returned by isInverse()
• <field> is the field alias returned by FieldConstraint#getField().getAlias()
• <casesensitive> is the value returned by isCaseSensitive()
• <operator> is the value returned by getOperator()
• <field2> is the field alias returned by #getField2().getAlias()

Specified by:

toString in interface CompareFieldsConstraint
