When an enabled StepRequest is satisfied, an `event set` containing a `StepEvent` will be placed on the `EventQueue`. The collection of existing StepRequests is managed by the `EventRequestManager` Since: 1.3 See Also: `StepEvent` `EventQueue` `EventRequestManager`

### field:STEP_INTO [NONE]
### STEP_INTO static final int STEP_INTO Step into any newly pushed frames See Also: Constant Field Values

### field:STEP_OVER [NONE]
### STEP_OVER static final int STEP_OVER Step over any newly pushed frames See Also: Constant Field Values

### field:STEP_OUT [NONE]
### STEP_OUT static final int STEP_OUT Step out of the current frame See Also: Constant Field Values

### field:STEP_MIN [NONE]
### STEP_MIN static final int STEP_MIN Step to the next available location See Also: Constant Field Values

### field:STEP_LINE [NONE]
### STEP_LINE static final int STEP_LINE Step to the next location on a different line See Also: Constant Field Values

### method:thread() [NONE]
### thread ThreadReference thread() Returns: the thread on which the step event is being requested.

### method:size() [NONE]
### size int size() Returns: the step size

### method:depth() [NONE]
### depth int depth() Returns: the step depth

### method:addClassFilter(com.sun.jdi.ReferenceType) [NONE]
### addClassFilter 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: `InvalidRequestStateException` - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

### method:addClassFilter(java.lang.String) [NONE]
### addClassFilter 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 or has been deleted. Filters may be added only to disabled requests.

### method:addClassExclusionFilter(java.lang.String) [NONE]
### addClassExclusionFilter void addClassExclusionFilter (String classPattern) Restricts the events generated by this request to those whose location is in a class whose name does not match 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 against. Throws: `InvalidRequestStateException` - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

### method:addInstanceFilter(com.sun.jdi.ObjectReference) [NONE]
### addInstanceFilter 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
