Method Detail

beginSection

public static void beginSection(java.lang.String name)

Writes a trace message to indicate that a given section of code has begun. This call must be followed by a corresponding call to endSection() on the same thread.

beginAsyncSection

public static void beginAsyncSection(java.lang.String name)

Writes a trace message to indicate that a given section of code has begun. Must be followed by a call to endAsyncSection(String) using the same tag. Unlike beginSection(String) and endSection(), asynchronous events do not need to be nested. The name and cookie used to begin an event must be used to end it.

Depending on provided Systracer instance, this method could vary in behavior and in DefaultTrace it is a no-op.

beginAsyncSection

public static void beginAsyncSection(java.lang.String name,
                                     int cookie)

Writes a trace message to indicate that a given section of code has begun. Must be followed by a call to endAsyncSection(String, int) using the same tag. Unlike beginSection(String) and endSection(), asynchronous events do not need to be nested. The name and cookie used to begin an event must be used to end it.

Depending on provided Systracer instance, this method could vary in behavior and in DefaultTrace it is a no-op.

beginSectionWithArgs

public static Systracer.ArgsBuilder beginSectionWithArgs(java.lang.String name)

endSection

public static void endSection()

Writes a trace message to indicate that a given section of code has ended. This call must be preceded by a corresponding call to beginSection(String). Calling this method will mark the end of the most recently begun section of code, so care must be taken to ensure that beginSection / endSection pairs are properly nested and called from the same thread.

endAsyncSection

public static void endAsyncSection(java.lang.String name)

Writes a trace message to indicate that the current method has ended. Must be called exactly once for each call to beginAsyncSection(String) using the same tag, name and cookie.

Depending on provided Systracer instance, this method could vary in behavior and in DefaultTrace it is a no-op.

endAsyncSection

public static void endAsyncSection(java.lang.String name,
                                   int cookie)

Writes a trace message to indicate that the current method has ended. Must be called exactly once for each call to beginAsyncSection(String, int) using the same tag, name and cookie.

Depending on provided Systracer instance, this method could vary in behavior and in DefaultTrace it is a no-op.
