StackSampleEvent

public StackSampleEvent(MetricType metricType,
 List<String> frames,
 long value,
 Instant timestamp)

Creates an instance of a StackSampleEvent record class.

Parameters:

metricType - the value for the metricType record component

frames - the value for the frames record component

value - the value for the value record component

timestamp - the value for the timestamp record component

StackSampleEvent

public StackSampleEvent(MetricType metricType,
 List<String> frames,
 long value)

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 '=='.

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.

metricType

public MetricType metricType()

Returns the value of the metricType record component.

Returns:

the value of the metricType record component

frames

public List<String> frames()

Returns the value of the frames record component.

Returns:

the value of the frames record component

value

public long value()

Returns the value of the value record component.

Returns:

the value of the value record component

timestamp

public Instant timestamp()

Returns the value of the timestamp record component.

Specified by:

timestamp in interface ProfileEvent

Returns:

the value of the timestamp record component
