Method Detail

getFilePath

public static java.lang.String getFilePath(org.eclipse.jdt.core.IJavaElement javaElt)

getPackageName

public static java.lang.String getPackageName(org.eclipse.jdt.core.ICompilationUnit cu)

getFullyQualifiedClassName

public static java.lang.String getFullyQualifiedClassName(org.eclipse.jdt.core.IType type)

getClassName

public static java.lang.String getClassName(org.eclipse.jdt.core.IType type)

getJdtHandleString

public static java.lang.String getJdtHandleString(org.eclipse.jdt.core.IJavaElement javaElt)

Return a unique string representing the specified Java element across projects in the workspace. The returned string can be used as a handle to create JavaElement by 'JavaCore.create(String)' For example, suppose we have the method 'fooPackage.barPackage.FooClass.fooMethod(int)' which is in the 'FooProject' and source folder 'src' the handle would be '=FooProject/src

Parameters:

javaElt -

Throws:

java.lang.IllegalArgumentException - if javaElt is null

createJavaElementFromJdtHandle

public static org.eclipse.jdt.core.IJavaElement createJavaElementFromJdtHandle(java.lang.String jdtHandle)

getClasses

getHumanReadableType

public static java.lang.String getHumanReadableType(java.lang.String typeSignature)

Parameters:

typeSignature - Some of the type signatures examples are "QString;" (String) and "I" (int) The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.
