Constructor Detail

BasicFieldValueDateConstraint

public BasicFieldValueDateConstraint(StepField field,
                                     Object value,
                                     int part)

Constructor. Depending on the field type, the value must be of type String or Number.

Parameters:

field - The associated field.

value - The non-null property value.

part - Which part of the date to compare

Throws:

IllegalArgumentException - when an invalid argument is supplied.

Method Detail

getPart

public int getPart()

Description copied from interface: FieldValueDateConstraint

Returns the part of the date-field wich is to be compared.

Specified by:

getPart in interface FieldValueDateConstraint

getPartDescription

public String getPartDescription()

Returns a description of the part

setPart

public void setPart(int p)

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 BasicFieldValueConstraint

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 BasicFieldValueConstraint

toString

public String toString()

Description copied from interface: FieldValueConstraint

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

• <inverse>is the value returned by isInverse()
• <field> is the field alias returned by FieldConstraint#getField().getAlias(), or FieldConstraint#getField().getFieldName() when the former is null.
• <casesensitive> is the value returned by isCaseSensitive()
• <operator> is the value returned by (@link FieldCompareConstraint#getOperator getOperator()}
• <value> is the value returned by getValue()

Specified by:

toString in interface FieldValueConstraint

Overrides:

toString in class BasicFieldValueConstraint

Returns:

A string representation of this FieldValueConstraint.
