jdk.lang.management.MonitorInfo — clojure-interop/java.lang.management 1.0.5

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.

*from clj

(*from 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:

Attribute Name Type

lockedStackFrame CompositeData as specified in the stackTrace attribute defined in the ThreadInfo.from method.

lockedStackDepth java.lang.Integer

cd - CompositeData representing a MonitorInfo - javax.management.openmbean.CompositeData

returns: a MonitorInfo object represented by cd if cd is not null; null otherwise. - java.lang.management.MonitorInfo

throws: java.lang.IllegalArgumentException - if cd does not represent a MonitorInfo with the attributes described above.

->monitor-info clj

(->monitor-info class-name identity-hash-code stack-depth stack-frame)

Constructor.

Construct a MonitorInfo object.

class-name - the fully qualified name of the class of the lock object. - java.lang.String identity-hash-code - the identity hash code of the lock object. - int stack-depth - the depth in the stack trace where the object monitor was locked. - int stack-frame - the stack frame that locked the object monitor. - java.lang.StackTraceElement

throws: java.lang.IllegalArgumentException - if stackDepth ≥ 0 but stackFrame is null, or stackDepth < 0 but stackFrame is not null.

get-locked-stack-depth clj

(get-locked-stack-depth this)

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. - int

get-locked-stack-frame clj

(get-locked-stack-frame this)

Returns the stack frame that locked the object monitor.

returns: StackTraceElement that locked the object monitor, or null if not available. - java.lang.StackTraceElement
