TraceContext

public TraceContext(String traceId,
 String spanId,
 byte traceFlags)

Create a TraceContext.

Method Details

isSampled

public boolean isSampled()

Check if this context is sampled.

Returns:

true if sampled

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.

traceId

public String traceId()

Returns the value of the traceId record component.

Returns:

the value of the traceId record component

spanId

public String spanId()

Returns the value of the spanId record component.

Returns:

the value of the spanId record component

traceFlags

public byte traceFlags()

Returns the value of the traceFlags record component.

Returns:

the value of the traceFlags record component
