Constructor Detail

BasicFieldConstraint

protected BasicFieldConstraint(StepField field)

Constructor. Protected, so only subclasses can be instantiated.

Parameters:

field - The associated field.

Throws:

IllegalArgumentException - when an invalid argument is supplied.

Method Detail

setCaseSensitive

public BasicFieldConstraint setCaseSensitive(boolean caseSensitive)

Sets caseSensitive property. This has only effect when the associated field is of string type.

Parameters:

caseSensitive - The caseSensitive property value.

Returns:

This BasicFieldConstraint instance.

matches

public boolean matches(Object o)

Description copied from interface: FieldConstraint

Determines whether a certain given value would match this constraint.

Specified by:

matches in interface FieldConstraint

getField

public StepField getField()

Description copied from interface: FieldConstraint

Gets the associated stepfield.

Specified by:

getField in interface FieldConstraint

isCaseSensitive

public boolean isCaseSensitive()

Description copied from interface: FieldConstraint

Tests if a the string comparison is case sensitive. This property is ignored if the associated field is not of string type.

Specified by:

isCaseSensitive in interface FieldConstraint

equals

public boolean equals(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 BasicConstraint

Parameters:

obj - The object to compare with.

Returns:

true if the objects are equal, false otherwise.

hashCode

public int hashCode()

Specified by:

hashCode in interface Constraint

Overrides:

hashCode in class BasicConstraint

getFieldName

public String getFieldName()

Returns the main field's fieldname, possibly extended with the step'sname if known. May return null or partial fieldnames if not all data is available (for use in debugging).

toString

public String toString()

Overrides:

toString in class Object
