Module Version: 2.14   Source   Latest Release: Treex-PML-2.17

NAME ^

Treex::PML::Instance::Writer

DESCRIPTION ^

This module provides implements the save() method of Treex::PML::Instance and is not intended for direct use.

IMPLEMENTATION NOTES ^

The module analyses a Treex::PML::Schema and generates Perl code to serialize PML instances conforming to that schema (by generating handlers for individual data types). The Perl code generated by this module transforms Treex::PML objects directly into XML (we intentionally avoid using of abstract interfaces like SAX or XML::Writer for speed).

The handlers for last 50 PML schemas are cached in memory, to boost processing large collections of PML instances conforming to only a few distinct schemas.

The module also implements automatic pluggable XSLT post-processing (transformation) of the resulting document; this post-processing can be specified in a configuration file (pmlbackend_conf.xml, see "CONFIGURATION" in Treex::PML::Instance for more details).

TODO ^

Implement post-processing via an external command or Perl module.

DEBUGGING ^

If the environment variable PML_COMPILE_DUMP=1 is set, the module dumps the generated code to the .pml_compile.d/ folder in the current working directory. This is very for debugging or profiling the generated code.
