public class StringValue
extends StringCondition

A String related condition class that compares a String value to another. The arguments being evaluated are adapted to a String first using a StringAdapter and then the string will be compared with the initialization string to see if they are equal.

Constructor Summary

StringValue(String string)
A simple constructor that takes an initialization String to match against.

StringValue(String string, boolean caseSensitive)
A simple constructor that takes an initialization String to match against.

StringValue(String string, boolean caseSensitive, IDataTypeAdapter<String> adapter)
A simple constructor that takes an initialization String to match against, a StringAdapter for adapting the evaluated object to string before matching them and a boolean flag indicating whether the pattern matching should be case-sensitive or not.

StringValue(String string, boolean caseSensitive, StringAdapter adapter)
A simple constructor that takes an initialization String to match against, a StringAdapter for adapting the evaluated object to string before matching them and a boolean flag indicating whether the pattern matching should be case-sensitive or not.

Method Summary

protected String	getString() A getter function for the String used by this StringValue condition for comparison with other argument string
protected boolean	isCaseSensitive() A getter function for the case-sensitive value used by this StringValue condition

Constructor Detail

StringValue

public StringValue(String string)

A simple constructor that takes an initialization String to match against. It defaults to using the StringAdapter.DEFAULT for adapting the evaluated object to string before matching them, and it defaults to being case-sensitive.

Parameters:

string - the initialization String to use for equality testing

StringValue

public StringValue(String string,
                   boolean caseSensitive)

A simple constructor that takes an initialization String to match against. It defaults to using the StringAdapter.DEFAULT for adapting the evaluated object to string before matching them.

Parameters:

string - the initialization String to use for equality testing

caseSensitive - a boolean value specifying whether to use case in matching strings

StringValue

public StringValue(String string,
                   boolean caseSensitive,
                   StringAdapter adapter)

A simple constructor that takes an initialization String to match against, a StringAdapter for adapting the evaluated object to string before matching them and a boolean flag indicating whether the pattern matching should be case-sensitive or not.

Parameters:

string - the initialization String to use for equality testing

caseSensitive - a boolean value specifying whether to use case in matching strings

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

StringValue

public StringValue(String string,
                   boolean caseSensitive,
                   IDataTypeAdapter<String> adapter)

A simple constructor that takes an initialization String to match against, a StringAdapter for adapting the evaluated object to string before matching them and a boolean flag indicating whether the pattern matching should be case-sensitive or not.

Parameters:

string - the initialization String to use for equality testing

caseSensitive - a boolean value specifying whether to use case in matching strings

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

Method Detail

isSatisfied

public boolean isSatisfied(String str)

Tests whether the argument string equals to the initialization String.

Specified by:

isSatisfied in class StringCondition

Parameters:

str - The String to evaluate

Returns:

boolean true if the argument string satisfies this StringCondition, false otherwise

See Also:

StringCondition.isSatisfied(java.lang.String)

isCaseSensitive

protected final boolean isCaseSensitive()

A getter function for the case-sensitive value used by this StringValue condition

Returns:

boolean indicating whether or not to compare string in case-sensitive manner or not.

getString

protected final String getString()

A getter function for the String used by this StringValue condition for comparison with other argument string

Returns:

The initialization String that this StringValue condition uses for testing
