Doc from com.sun.tools.attach.spi.AttachProvider.attachVirtualMachine. Attaches to a Java virtual machine. A Java virtual machine is identified by an abstract identifier.

Attaches to a Java virtual machine.

A Java virtual machine is identified by an abstract identifier. The nature of this identifier is platform dependent but in many cases it will be the string representation of the process identifier (or pid).

This method parses the identifier and maps the identifier to a Java virtual machine (in an implementation dependent manner). If the identifier cannot be parsed by the provider then an AttachNotSupportedException is thrown. Once parsed this method attempts to attach to the Java virtual machine. If the provider detects that the identifier corresponds to a Java virtual machine that does not exist, or it corresponds to a Java virtual machine that does not support the attach mechanism implemented by this provider, or it detects that the Java virtual machine is a version to which this provider cannot attach, then an AttachNotSupportedException is thrown.

Parameters

vmid:String: The abstract identifier that identifies the Java virtual machine.

Returns:VirtualMachine

VirtualMachine representing the target virtual machine.

Exceptions

AttachNotSupportedException:: If the identifier cannot be parsed, or it corresponds to to a Java virtual machine that does not exist, or it corresponds to a Java virtual machine which this provider cannot attach.
IOException:: If some other I/O error occurs

public VirtualMachine attachVirtualMachine(VirtualMachineDescriptor vmd) throws AttachNotSupportedException, IOException Overrides com.sun.tools.attach.spi.AttachProvider.attachVirtualMachine. Doc from com.sun.tools.attach.spi.AttachProvider.attachVirtualMachine. Attaches to a Java virtual machine. A Java virtual machine can be described using a `VirtualMachineDescriptor`. This method invokes the descriptor's `provider()` method to check that it is equal to this provider. It then attempts to attach to the Java virtual machine. Parameters vmd:VirtualMachineDescriptor The virtual machine descriptor Returns:VirtualMachine VirtualMachine representing the target virtual machine. Exceptions AttachNotSupportedException: If the descriptor's `provider()` method returns a provider that is not this provider, or it does not correspond to a Java virtual machine to which this provider can attach. IOException: If some other I/O error occurs

public VirtualMachine attachVirtualMachine(VirtualMachineDescriptor vmd) throws AttachNotSupportedException, IOException

Overrides com.sun.tools.attach.spi.AttachProvider.attachVirtualMachine.

Doc from com.sun.tools.attach.spi.AttachProvider.attachVirtualMachine.

Attaches to a Java virtual machine.

A Java virtual machine can be described using a VirtualMachineDescriptor. This method invokes the descriptor's provider() method to check that it is equal to this provider. It then attempts to attach to the Java virtual machine.

Parameters

vmd:VirtualMachineDescriptor: The virtual machine descriptor

Returns:VirtualMachine

VirtualMachine representing the target virtual machine.

Exceptions

AttachNotSupportedException:: If the descriptor's provider() method returns a provider that is not this provider, or it does not correspond to a Java virtual machine to which this provider can attach.
IOException:: If some other I/O error occurs
