Method Detail

dump

public void dump(Object object,
                 DebugContext debug,
                 boolean forced,
                 String format,
                 Object... arguments)

Description copied from interface: DebugDumpHandler

If the type of object is supported by this dumper, then a representation of object is sent to some consumer in a format determined by this object.

Specified by:

dump in interface DebugDumpHandler

Parameters:

object - the object to be dumped

debug - the debug context requesting the dump

forced - true if called from DebugContext.forceDump(Object, String, Object...)

format - a format string specifying a title that describes the context of the dump (e.g., the compiler phase in which request is made)

arguments - arguments referenced by the format specifiers in format

close

public void close()

Description copied from interface: DebugDumpHandler

Flushes and releases resources managed by this dump handler. A subsequent call to DebugDumpHandler.dump(java.lang.Object, org.graalvm.compiler.debug.DebugContext, boolean, java.lang.String, java.lang.Object...) will create and open new resources. That is, this method can be used to reset the handler.
