JfrMethodObservation

public JfrMethodObservation(Path recordingFile,
 int workloadInvocations,
 long checksum,
 int methodTraceCount,
 int methodTimingCount,
 long timedInvocations,
 List<String> methodNames)

Creates an instance of a JfrMethodObservation record class.

Parameters:

recordingFile - the value for the recordingFile record component

workloadInvocations - the value for the workloadInvocations record component

checksum - the value for the checksum record component

methodTraceCount - the value for the methodTraceCount record component

methodTimingCount - the value for the methodTimingCount record component

timedInvocations - the value for the timedInvocations record component

methodNames - the value for the methodNames record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

recordingFile

public Path recordingFile()

Returns the value of the recordingFile record component.

Returns:

the value of the recordingFile record component

workloadInvocations

public int workloadInvocations()

Returns the value of the workloadInvocations record component.

Returns:

the value of the workloadInvocations record component

checksum

public long checksum()

Returns the value of the checksum record component.

Returns:

the value of the checksum record component

methodTraceCount

public int methodTraceCount()

Returns the value of the methodTraceCount record component.

Returns:

the value of the methodTraceCount record component

methodTimingCount

public int methodTimingCount()

Returns the value of the methodTimingCount record component.

Returns:

the value of the methodTimingCount record component

timedInvocations

public long timedInvocations()

Returns the value of the timedInvocations record component.

Returns:

the value of the timedInvocations record component

methodNames

public List<String> methodNames()

Returns the value of the methodNames record component.

Returns:

the value of the methodNames record component
