public class StringLength
extends StringCondition

A Condition object that tests for String length values. The arguments being evaluated are adapted to a String first using a StringAdapter and then the length of the string will be compared with the initialization numeric values to see if it is equal/in-range.

Constructor Detail

StringLength

public StringLength(int length)

A simple constructor that takes one int argument to test strings' length against It evaluates to true when the evaluated String length equals the length initialization argument. It defaults to using the StringAdapter.DEFAULT for adapting the evaluated object to string before getting their length.

Parameters:

length - The int value that the evaluated string length must match

StringLength

public StringLength(int length,
                    StringAdapter adapter)

A constructor that takes one int argument to test strings' length against and a StringAdapter. It evaluates to true when the evaluated String length equals the length initialization argument. It uses the argument StringAdapter for adapting the evaluated object to string before getting their length.

Parameters:

length - The int value that the evaluated string length must match

adapter - The StringAdapter to use to get a String out of evaluated Objects

StringLength

public StringLength(int length,
                    IDataTypeAdapter<String> adapter)

A constructor that takes one int argument to test strings' length against and a StringAdapter. It evaluates to true when the evaluated String length equals the length initialization argument. It uses the argument StringAdapter for adapting the evaluated object to string before getting their length.

Parameters:

length - The int value that the evaluated string length must match

adapter - a generic string adapter to use to get a String out of evaluated Objects

Since:

1.2

StringLength

public StringLength(int lowerBound,
                    int upperBound)

A constructor that takes two int arguments representing a range to test strings' length against. It evaluates to true when the evaluated String length is equal to any these two int values passed or fall in between. It defaults to using the StringAdapter.DEFAULT for adapting the evaluated object to string before getting their length.

Parameters:

lowerBound - the int value representing the lower-bound in range testing

upperBound - the int value representing the upper-bound in range testing

StringLength

public StringLength(int lowerBound,
                    int upperBound,
                    StringAdapter adapter)

A constructor that takes two int arguments representing a range to test strings' length against. It evaluates to true when the evaluated String length is equal to any these two int values passed or fall in between. It uses the argument StringAdapter for adapting the evaluated object to string before getting their length.

Parameters:

lowerBound - the int value representing the lower-bound in range testing

upperBound - the int value representing the upper-bound in range testing

adapter - The StringAdapter to use to get a String out of evaluated Objects

StringLength

public StringLength(int lowerBound,
                    int upperBound,
                    IDataTypeAdapter<String> adapter)

A constructor that takes two int arguments representing a range to test strings' length against. It evaluates to true when the evaluated String length is equal to any these two int values passed or fall in between. It uses the argument StringAdapter for adapting the evaluated object to string before getting their length.

Parameters:

lowerBound - the int value representing the lower-bound in range testing

upperBound - the int value representing the upper-bound in range testing

adapter - a generic string adapter to use to get a String out of evaluated Objects
