是否可以在 Eclipse 中创建自定义变量查看器?假设我希望分解位域或将位图视为图像。是否可以?
你能举一些最简单的例子吗?
更新
我plugin.xml
的如下:
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin>
<extension
point="org.eclipse.debug.ui.detailPaneFactories">
<detailFactories
class="tests.debug.details.DetailPaneFactory"
id="tests.debug.details.detailFactories">
</detailFactories>
</extension>
</plugin>
我DetailPaneFactory.java
的如下:
package tests.debug.details;
import java.util.AbstractSet;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;
import org.eclipse.debug.ui.IDetailPane;
import org.eclipse.debug.ui.IDetailPaneFactory;
import org.eclipse.jface.viewers.IStructuredSelection;
public class DetailPaneFactory implements IDetailPaneFactory {
private HashMap<String,Class<? extends IDetailPane>> classes = new HashMap<String,Class<? extends IDetailPane>>();
private void addClass(Class<? extends IDetailPane> cls) {
try {
String paneID = (String) cls.getField("ID").get(null);
classes.put(paneID, cls);
} catch (IllegalArgumentException | IllegalAccessException
| NoSuchFieldException | SecurityException e) {
throw new RuntimeException(e);
}
finally {
}
}
private Class<? extends IDetailPane> getClass(String paneID) {
Class<? extends IDetailPane> ans = classes.get(paneID);
return ans;
}
public DetailPaneFactory() {
addClass(SimpleDetailPane.class);
}
@Override
public IDetailPane createDetailPane(String paneID) {
Class<? extends IDetailPane> cls = getClass(paneID);
if( cls != null ) {
try {
return cls.newInstance();
} catch (InstantiationException | IllegalAccessException e) {
throw new RuntimeException();
}
}
else {
return null;
}
}
@Override
public String getDetailPaneName(String paneID) {
Class<? extends IDetailPane> cls = getClass(paneID);
if( cls != null ) {
try {
return (String)cls.getField("NAME").get(null);
} catch (IllegalArgumentException | IllegalAccessException
| NoSuchFieldException | SecurityException e) {
throw new RuntimeException(e);
}
}
else {
return null;
}
}
@Override
public String getDetailPaneDescription(String paneID) {
Class<? extends IDetailPane> cls = getClass(paneID);
if( cls != null ) {
try {
return (String)cls.getField("DESCRIPTION").get(null);
} catch (IllegalArgumentException | IllegalAccessException
| NoSuchFieldException | SecurityException e) {
throw new RuntimeException(e);
}
}
else {
return null;
}
}
@Override
public Set<String> getDetailPaneTypes(IStructuredSelection selection) {
return new AbstractSet<String>() {
@Override
public Iterator<String> iterator() {
return new Iterator<String>() {
private Iterator<Map.Entry<String,Class<? extends IDetailPane>>> it = classes.entrySet().iterator();
@Override
public void remove() {
it.remove();
}
@Override
public String next() {
return it.next().getKey();
}
@Override
public boolean hasNext() {
return it.hasNext();
}
};
}
@Override
public int size() {
return classes.size();
}
};
}
@Override
public String getDefaultDetailPane(IStructuredSelection selection) {
return SimpleDetailPane.ID;
}
}
我SimpleDetailPane.java
的就像例子一样。
它显然有效。
