All Implemented Interfaces:

java.io.Serializable, TestSource

@API(status=STABLE,
     since="1.0")
public class ClassSource
extends java.lang.Object
implements TestSource

Class based TestSource with an optional file position.

If a Java Class reference is provided, the ClassSource will contain that Class and its class name accordingly. If a class name is provided, the ClassSource will contain the class name and will only attempt to lazily load the Class if getJavaClass() is invoked.

In this context, Java Class means anything that can be referenced as a Class on the JVM — for example, classes from other JVM languages such Groovy, Scala, etc.

Method Detail

from

public static ClassSource from(java.lang.String className)

Create a new ClassSource using the supplied class name.

Parameters:

className - the class name; must not be null or blank

from

public static ClassSource from(java.lang.String className,
                               FilePosition filePosition)

Create a new ClassSource using the supplied class name and file position.

Parameters:

className - the class name; must not be null or blank

filePosition - the position in the source file; may be null

from

public static ClassSource from(java.lang.Class<?> javaClass)

Create a new ClassSource using the supplied class.

Parameters:

javaClass - the Java class; must not be null

from

public static ClassSource from(java.lang.Class<?> javaClass,
                               FilePosition filePosition)

Create a new ClassSource using the supplied class and file position.

Parameters:

javaClass - the Java class; must not be null

filePosition - the position in the Java source file; may be null

getClassName

public final java.lang.String getClassName()

Get the class name of this source.

See Also:

getJavaClass(), getPosition()

getJavaClass

public final java.lang.Class<?> getJavaClass()

Get the Java class of this source.

If the Class was not provided, but only the name, this method attempts to lazily load the Class based on its name and throws a PreconditionViolationException if the class cannot be loaded.

getClassName(), getPosition()

getPosition

public final java.util.Optional<FilePosition> getPosition()

Get the position in the source file for the associated class, if available.
