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

dumpSandboxed

public void dumpSandboxed(DebugContext debug,
                          Object object,
                          boolean forced,
                          String message)

dumpSandboxed

public void dumpSandboxed(DebugContext debug,
                          Object object,
                          String message)

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.
