#define ION_ATRACE_CALL ( ) ion::port::android::ScopedTrace ___tracer(ION_ATRACE_TAG, __FUNCTION__)

ION_ATRACE_CALL traces the beginning and end of the current function.

To trace the correct start and end times this macro should be the first line of the function body.

Definition at line 89 of file trace.h.

#define ION_ATRACE_ENABLED ( ) ion::port::android::Tracer::isTagEnabled(ION_ATRACE_TAG)

ION_ATRACE_ENABLED returns true if the trace tag is enabled.

It can be used as a guard condition around more expensive trace calculations.

Definition at line 105 of file trace.h.

#define ION_ATRACE_INT	(	name,
		value
	)	ion::port::android::Tracer::traceCounter(ION_ATRACE_TAG, name, value)

ION_ATRACE_INT traces a named integer value.

This can be used to track how the value changes over time in a trace.

Definition at line 100 of file trace.h.

#define ION_ATRACE_NAME ( name ) ion::port::android::ScopedTrace ___tracer(ION_ATRACE_TAG, name)

ION_ATRACE_NAME traces the beginning and end of the current function.

To trace the correct start and end times this macro should be the first line of the function body.

The ION_ATRACE_TAG macro can be defined before including this header to trace using one of the tags defined below. It must be defined to one of the following ION_ATRACE_TAG_* macros. The trace tag is used to filter tracing in userland to avoid some of the runtime cost of tracing when it is not desired.

Defining ION_ATRACE_TAG to be ION_ATRACE_TAG_ALWAYS will result in the tracing always being enabled - this should ONLY be done for debug code, as userland tracing has a performance cost even when the trace is not being recorded. Defining ION_ATRACE_TAG to be ION_ATRACE_TAG_NEVER or leaving ION_ATRACE_TAG undefined will result in the tracing always being disabled.

These tags must be kept in sync with frameworks/base/core/java/android/os/Trace.java.
