Class Gprof.GprofConverter

java.lang.Object
  com.codemesh.terp.data.Gprof.GprofConverter

All Implemented Interfaces:

Converter<Gprof.GprofExecutor>

Enclosing interface:

Gprof

public static class Gprof.GprofConverter
extends java.lang.Object
implements Converter<Gprof.GprofExecutor>

A converter that creates an Gprof.GprofExecutor for the gprof profiling utility. This converter is registered with the terp runtime under the ^gprof alias. In addition to supporting initialization from String and File, this converter has a default (null or empty map) initializer that simply looks for an installed copy of gprof and returns it.

To locate an installed copy of gprof, the following rules are used:

1. Run "which gprof".
2. If nothing was found, inspect some well known directories for copies of gprof.

Method Detail

fromObject

public Gprof.GprofExecutor fromObject(java.lang.Object obj,
                                      TerpContext ctx)

Converts the given object into an object of the target type. Conversions can be implemented in any way that makes sense. Normally, converters will return null for null, but some converters may choose to interpret null as an indicator to return a default-initialized target object. An example of this type of conversion is the ShellExecutor. null simply indicates that no preference overrides of any kind have been provided. This converter interprets null or an empty input map as a request for the default instance of gprof.

Specified by:

fromObject in interface Converter<Gprof.GprofExecutor>

Parameters:

obj - the source object.

ctx - the context in which the conversion takes place.

Returns:

an instance of the target type or null.
