addThreadFilter

public void addThreadFilter(ThreadReference thread)
Restricts the events generated by this request to those in this thread.
Parameters:
thread - the thread to filter on.
Throws:
VMMismatchException - if a Mirror argument and this mirror do not belong to the same VirtualMachine.
InvalidRequestStateException - if this request is currently enabled. Filters may be added only to disabled requests.

addClassFilter

public void addClassFilter(ReferenceType refType)
Restricts the events generated by this request to those whose location 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:
VMMismatchException - if a Mirror argument and this mirror do not belong to the same VirtualMachine.
InvalidRequestStateException - if this request is currently enabled. Filters may be added only to disabled requests.

addClassFilter

public void addClassFilter(String classPattern)
Restricts the events generated by this request to those whose location is in a class whose name matches a 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. Filters may be added only to disabled requests.

addClassExclusionFilter

public void addClassExclusionFilter(String classPattern)
Restricts the events generated by this request to those whose location is in a class whose name does not match this restricted regular expression. Regular expressions are limited to exact matches and patterns that begin with '*' or end with '*'; for example, "*.Foo" or "java.*".
