IDSizes Command (7)

Returns the sizes of variably-sized data types in the target VM.The returned values indicate the number of bytes used by the identifiers in command and reply packets.

Out Data

(None)

Reply Data
int fieldIDSize fieldID size in bytes
int methodIDSize methodID size in bytes
int objectIDSize objectID size in bytes
int referenceTypeIDSize referenceTypeID size in bytes
int frameIDSize frameID size in bytes

EventRequest Command Set (15)
Set Command (1)

Set an event request. When the event described by this request occurs, an event is sent from the target VM. If an event occurs that has not been requested then it is not sent from the target VM. The two exceptions to this are the VM Start Event and the VM Death Event which are automatically generated events - see Composite Command for further details.

事件请求命令集 (15)

设置命令 (1)

设置事件请求。 当此请求描述的事件发生时，将从目标 VM 发送一个事件。 如果发生未请求的事件，则不会从目标 VM 发送该事件。 两个例外是 VM 启动事件和 VM 死亡事件，它们是自动生成的事件 - 有关更多详细信息，请参阅复合命令。

VirtualMachine Command Set (1)

Returns the JDWP version implemented by the target VM. The version string format is implementation dependent.

Version Command (1)

Returns the JDWP version implemented by the target VM. The version string format is implementation dependent.

Out Data

(None)

Reply Data
string description Text information on the VM version
int jdwpMajor Major JDWP Version number
int jdwpMinor Minor JDWP Version number
string vmVersion Target VM JRE version, as in the java.version property
string vmName Target VM name, as in the java.vm.name property

从IDE接收到的packet->ID=10/Virtual Machine(1)/Capabilities(12)/0/

proxy->ide packet:ID=10/(0)/(0)/0/00000000000000

Capabilities Command (12)

Retrieve this VM's capabilities. The capabilities are returned as booleans, each indicating the presence or absence of a capability. The commands associated with each capability will return the NOT_IMPLEMENTED error if the cabability is not available.

Out Data

(None)

Reply Data
boolean canWatchFieldModification Can the VM watch field modification, and therefore can it send the Modification Watchpoint Event?
boolean canWatchFieldAccess Can the VM watch field access, and therefore can it send the Access Watchpoint Event?
boolean canGetBytecodes Can the VM get the bytecodes of a given method?
boolean canGetSyntheticAttribute Can the VM determine whether a field or method is synthetic? (that is, can the VM determine if the method or the field was invented by the compiler?)
boolean canGetOwnedMonitorInfo Can the VM get the owned monitors infornation for a thread?
boolean canGetCurrentContendedMonitor Can the VM get the current contended monitor of a thread?
boolean canGetMonitorInfo Can the VM get the monitor information for a given object?
