Enum Constant Summary

Enum Constants

Enum Constant	Description
FENCE_COMPLETION	An asynchronous GL fence reports CPU-observed completion latency.
NONE	No GPU measurement is active; CPU profiling remains available.
TIME_ELAPSED_EXCLUSIVE	One exclusive asynchronous GL_TIME_ELAPSED query delimits GPU execution.
TIMESTAMP_PAIR	Two asynchronous GL_TIMESTAMP queries delimit GPU execution.

Method Summary

Modifier and Type	Method	Description
static GpuTimerBackend	valueOf(String name)	Returns the enum constant of this class with the specified name.
static GpuTimerBackend[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

NONE

public static final GpuTimerBackend NONE

No GPU measurement is active; CPU profiling remains available.

TIMESTAMP_PAIR

public static final GpuTimerBackend TIMESTAMP_PAIR

Two asynchronous GL_TIMESTAMP queries delimit GPU execution.

TIME_ELAPSED_EXCLUSIVE

public static final GpuTimerBackend TIME_ELAPSED_EXCLUSIVE

One exclusive asynchronous GL_TIME_ELAPSED query delimits GPU execution.

FENCE_COMPLETION

public static final GpuTimerBackend FENCE_COMPLETION

An asynchronous GL fence reports CPU-observed completion latency.

This backend is deliberately distinct from timer-query backends: it does not expose a GPU clock duration. It measures the latency from the CPU-side beginning of the profiled interval until a later non-blocking poll observes the end fence as complete.

Method Details

values

public static GpuTimerBackend[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static GpuTimerBackend valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
