Method Detail

convert_template

public int convert_template(java.lang.Object form,
                   SyntaxForm syntax,
                   java.lang.StringBuffer template_program,
                   int nesting,
                   java.util.Vector literals_vector,
                   java.lang.Object seen,
                   boolean isVector,
                   Translator tr)

Recursively translate a syntax-rule template to a template program.

Parameters:

form - the template from the syntax-rule

syntax - if non-null, the closest surrounding SyntaxForm

template_program - (output) the translated template

nesting - the depth of ... we are inside

literals_vector - (output) the literal data in the template

tr - the current Translator

Returns:

the index of a pattern variable (in pattern_names) that is nested at least as much as nesting; if there is none such, -1 if there is any pattern variable or elipsis; and -2 if the is no pattern variable or elipsis.

execute

public java.lang.Object execute(java.lang.Object[] vars,
                       TemplateScope templateScope)

Expand this template The compiler translates (syntax template) to a call to this method.

execute
