All Implemented Interfaces:

org.eclipse.core.expressions.IPropertyTester

public class OptimizedFilePropertyTester
extends org.eclipse.core.internal.propertytester.ResourcePropertyTester

A replacement for FilePropertyTester providing an optimized implementation for CONTENT_TYPE_ID property tests which significantly increases runtime performance when this kind of property test is applied to big numbers of files.

Since:

0.7.0

Method Detail

test

public boolean test(java.lang.Object receiver,
           java.lang.String method,
           java.lang.Object[] args,
           java.lang.Object expectedValue)

Specified by:

test in interface org.eclipse.core.expressions.IPropertyTester

Overrides:

test in class org.eclipse.core.internal.propertytester.ResourcePropertyTester

testContentType

protected boolean testContentType(org.eclipse.core.resources.IFile file,
                      java.lang.String contentTypeId)

Tests whether the content type for file matches the contentTypeId. It is possible that this method call could cause the file to be read. It is also possible (through poor plug-in design) for this method to load plug-ins.

Parameters:

file - The file for which the content type should be determined; must not be null.

contentTypeId - The expected content type; must not be null.

Returns:

true iff the best matching content type has an identifier that matches contentTypeId; false otherwise.
