| the other way around -> relating TRCMethod to IMethod [message #96865] |

Hi there,
a month ago Marius gave a very enlighting example how to use the
SimpleQueryEngine. With that i got access to the TraceModel and extracted
my method of interest successfully. Thanks Marius!
What i now would like to do is do relate the found TRCMethod to the
corresponding IMethod. I wrote a little HelperMethod wich looks like:
HelperMethods.getIMethod(fqClassName, methodName, paramTypes);
And here is my problem: TRCMethods' signature get's converted to a more
readable version through TraceUtils.convertMethodSignature(). What i need
is the 'original' signature to make the relation work in all cases.
Is there possibility to get access to the original signature (probably
through another query?) or do i have to reverse (assuming that it is
reversable) the function of TraceUtils.convertMethodSignature() to come to
the original signature?
Many thanks to all,
Thomas E.-E.

Hi Thomas,
Here are some suggestions.
Try to use the String org.eclipse.jdt.core.IMethod.getSignature() throws
JavaModelException to get the IMethod JNI signature and then use
TraceUtils.convertMethodSignature()to get the TRCMethod signature and then
use the TPTP model query engine to find the method by signature.
Two cases are shown here one with unqualified class names and one with one
parameter being qualified:
1. public String testname1(int i1, List L1) throws Exception
Params to Signature.createMethodSignature(String[], String) line: 530
=
parameterTypes String[2] = [I, QList;]
returnType = "QString;"
IMethod.getSignature() = (IQList;)QString;
2. public String testname1(int i1, java.util.List L1) throws Exception
Params to Signature.createMethodSignature(String[], String) line: 530
=
parameterTypes String[2] = [I, Qjava.util.List;]
returnType = "QString;"
IMethod.getSignature() = (IQjava.util.List;)QString;
<methodDef name="testname1"
signature="(ILjava/util/List;)Ljava/lang/String;" startLineNumber="20"
endLineNumber="20" methodId="5305" classIdRef="5309"/>
<methods id="5305" name="testname1" signature="(int, java.util.List)
java.lang.String" lineNo="20" baseTime="2.388830566406253E-7"
cumulativeTime="2.388830566406253E-7" calls="1"/>
If you can generate the fully quallified JNI signature from IMethod info
using String org.eclipse.jdt.core.Signature.createMethodSignature(String[ ]
parameterTypes, String returnType) then it should be easy to convert to
TRCMethod signature, see the attached test class (add JDT core plugin and
org.eclipse.tptp.platform.models to the class path):
Take a look at the boolean
org.eclipse.hyades.ui.internal.util.OpenJavaSource.openSourc e(String
pattern, int javaType, IJavaSearchScope searchScope, boolean
switchToJavaPerspective) an see if you can use the same approach to find the
corresponding IMethod/IClass from an TRCMethod/TRCClass.
OpenSource.openSource(Object) line: 43
selection TRCMethodImpl (id=228)
org.eclipse.hyades.models.trace.impl.TRCMethodImpl@1667f3c (id: 15605, name:
add, signature: (java.lang.String, java.awt.Component) java.awt.Component,
modifier: 0, notation: JNI, lineNo: 356, lineCount: 1, baseTime: 4.78991E-4,
cumulativeTime: 4.78991E-4, calls: 2, totalCpuTime: 0.0)
OpenJavaSource.openSource(String, int, IJavaSearchScope, boolean) line: 73
