Package Summary Overview Summary

### class:MonitorInfo [NONE]
public class MonitorInfo extends LockInfo Information about an object monitor lock. An object monitor is locked when entering a synchronization block or method on that object. ## MXBean Mapping `MonitorInfo` is mapped to a `CompositeData` with attributes as specified in the `from` method. Since: 1.6

### constructor:MonitorInfo(java.lang.String,int,int,java.lang.StackTraceElement) [NONE]
### MonitorInfo public MonitorInfo (String className, int identityHashCode, int stackDepth, StackTraceElement stackFrame) Construct a `MonitorInfo` object. Parameters: `className` - the fully qualified name of the class of the lock object. `identityHashCode` - the `identity hash code` of the lock object. `stackDepth` - the depth in the stack trace where the object monitor was locked. `stackFrame` - the stack frame that locked the object monitor. Throws: `IllegalArgumentException` - if `stackDepth` ≥ 0 but `stackFrame` is `null`, or `stackDepth` < 0 but `stackFrame` is not `null`.

### method:getLockedStackDepth() [NONE]
### getLockedStackDepth public int getLockedStackDepth() Returns the depth in the stack trace where the object monitor was locked. The depth is the index to the `StackTraceElement` array returned in the `ThreadInfo.getStackTrace()` method. Returns: the depth in the stack trace where the object monitor was locked, or a negative number if not available.

### method:getLockedStackFrame() [NONE]
### getLockedStackFrame public StackTraceElement getLockedStackFrame() Returns the stack frame that locked the object monitor. Returns: `StackTraceElement` that locked the object monitor, or `null` if not available.

### method:from(javax.management.openmbean.CompositeData) [NONE]
### from public static MonitorInfo from (CompositeData cd) Returns a `MonitorInfo` object represented by the given `CompositeData`. The given `CompositeData` must contain the following attributes as well as the attributes specified in the mapped type for the `LockInfo` class:
The attributes and their types the given CompositeData contains
Attribute Name | Type
--- | ---
lockedStackFrame | `CompositeData` for `StackTraceElement` as specified in `ThreadInfo.from(CompositeData)` method.
lockedStackDepth | `java.lang.Integer`
Parameters: `cd` - `CompositeData` representing a `MonitorInfo` Returns: a `MonitorInfo` object represented by `cd` if `cd` is not `null`; `null` otherwise. Throws: `IllegalArgumentException` - if `cd` does not represent a `MonitorInfo` with the attributes described above.
