Macro Definition Documentation

#define IMP_ERROR (   expr)

Write a warning to standard error.

Parameters
[in]exprAn expression to be output to std::cerr. It is prefixed by "ERROR"

Definition at line 61 of file log_macros.h.

#define IMP_FUNCTION_LOG   IMP::CreateLogContext log_context__(IMP_CURRENT_FUNCTION)

Beginning logging for a non-member function.

Definition at line 293 of file log_macros.h.

#define IMP_IF_LOG (   level)

Execute the code block if a certain level of logging is on.

The next code block (delimited by { }) is executed if get_log_level() >= level.

Floats testp(input.begin(), input.end());
std::sort(testp.begin(), testp.end());
IMP_LOG_VERBOSE( "Sorted order is ");
IMP_LOG_WRITE(VERBOSE, std::copy(testp.begin(), testp.end(),
std::ostream_iterator<double>(IMP_STREAM, " ")));
}

Definition at line 49 of file log_macros.h.

#define IMP_LOG_CONTEXT (   name)    IMP::CreateLogContext imp_log_context(name, nullptr)

Create a new log context from a streamed name.

Definition at line 297 of file log_macros.h.

#define IMP_LOG_PROGRESS (   expr)
Parameters
[in]exprA stream expression to be sent to the output stream if the log level is at least PROGRESS.

Usage:

IMP_LOG_PROGRESS( "Hi there, I'm very talkative. My favorite numbers are "
<< 1 << " " << 2 << " " << 3);

Definition at line 94 of file log_macros.h.

#define IMP_LOG_TERSE (   expr)
Parameters
[in]exprA stream expression to be sent to the output stream if the log level is at least TERSE.

Usage:

IMP_LOG_VERBOSE( "Hi there, I'm very talkative. My favorite numbers are "
<< 1 << " " << 2 << " " << 3);

Definition at line 72 of file log_macros.h.

#define IMP_LOG_VARIABLE (   variable)

Mark a variable as one that is only used in logging. This disables unused variable warnings on it in fast mode.

Definition at line 99 of file log_macros.h.

#define IMP_LOG_VERBOSE (   expr)
Parameters
[in]exprA stream expression to be sent to the output stream if the log level is at least VERBOSE.

Usage:

IMP_LOG_VERBOSE( "Hi there, I'm very talkative. My favorite numbers are "
<< 1 << " " << 2 << " " << 3);

Definition at line 83 of file log_macros.h.

#define IMP_OBJECT_LOG

Set the log level to the object's log level.

All non-trivial Object methods should start with this. It creates a RAII-style object which sets the log level to the local one, if appropriate, until it goes out of scope.

Definition at line 284 of file log_macros.h.

#define IMP_PROGRESS_DISPLAY (   name,
  steps 
)

Like IMP::set_progress_display() but you can use stream operations for the name.

Definition at line 316 of file log_macros.h.

#define IMP_WARN (   expr)

Write a warning to a log.

Parameters
[in]exprAn expression to be output to the log. It is prefixed by "WARNING"

Definition at line 55 of file log_macros.h.

#define IMP_WARN_ONCE (   key,
  expr,
  context 
)

Write a warning once per context object.

Use this macro to, for example, warn on unprocessable fields in a PDB, since they tend to come together. The key is what is tested for uniqueness, the expr is what is output.

Warnings are only output when the context object is destroyed.
