Java Debug Interface

com.sun.jdi.request
Interface MethodEntryRequest

All Superinterfaces:
EventRequest, Mirror

public interface MethodEntryRequest
extends EventRequest

Request for notification when a method is invoked in the target VM. When an enabled MethodEntryRequest is satisfied, an event set containing a MethodEntryEvent will be placed on the EventQueue. The collection of existing MethodEntryRequests is managed by the EventRequestManager

 void addInstanceFilter(ObjectReference instance)
          Restricts the events generated by this request to those in which the currently executing instance ("this") is the object specified.
 void addThreadFilter(ThreadReference thread)
          Restricts the events generated by this request to those in the given thread.

Method Detail

addThreadFilter

public void addThreadFilter(ThreadReference thread)
Restricts the events generated by this request to those in the given thread.

Parameters:
thread - the thread to filter on.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassFilter

public void addClassFilter(ReferenceType refType)
Restricts the events generated by this request to those whose method is in the given reference type or any of its subtypes. An event will be generated for any location in a reference type that can be safely cast to the given reference type.

Parameters:
refType - the reference type to filter on.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassFilter

public void addClassFilter(String classPattern)
Restricts the events generated by this request to those whose method is in a class whose name matches this restricted regular expression. Regular expressions are limited to exact matches and patterns that begin with '*' or end with '*'; for example, "*.Foo" or "java.*".

Parameters:
classPattern - the pattern String to filter for.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassExclusionFilter

public void addClassExclusionFilter(String classPattern)
Restricts the events generated by this request to those whose method is in a class whose name does not match this restricted regular expression, e.g. "java.*" or "*.Foo".

Parameters:
classPattern - the pattern String to filter against.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addInstanceFilter

public void addInstanceFilter(ObjectReference instance)
Restricts the events generated by this request to those in which the currently executing instance ("this") is the object specified.

Not all targets support this operation. Use VirtualMachine.canUseInstanceFilters() to determine if the operation is supported.

Parameters:
instance - the object which must be the current instance in order to pass this filter.
Throws:
UnsupportedOperationException - if the target virtual machine does not support this operation.
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.
Since:
1.4
