  org.semanticdesktop.aperture.datasource.config.SubstringCondition

Direct Known Subclasses:

SubstringCondition.Contains, SubstringCondition.DoesNotContain, SubstringCondition.EndsWith, SubstringCondition.StartsWith

public abstract class SubstringCondition
extends Object

Instances of this class indicate how a substring test needs to be performed and are able to evaluate the test. Subclasses embody a particular kind of substring test, e.g. "starts with", "ends with" or "contains".

Method Detail

test

public abstract boolean test(String string,
                             String substring)

Tests the substring condition embodied by the implementing class on a String.

Parameters:

string - The String to test the substring condition on.

substring - The String to test the substring condition with.

Returns:

'true' when the string contains the substring in the way embodied by the implementing class, 'false' otherwise.

toNode

public abstract Node toNode()

Return the Value used to encode this SubstringCondition in an RDF model.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
