Enhanced compiled representation of transformation formats

Abstract

Enhanced compiled representation of transformation formats to enable rapid application development and deployment is disclosed. Techniques for generating a run-time instance include taking an expression from a parser, tokenizing the expression using a node and an axis type, selecting an operation using the axis type, and generating the run-time instance using the operation. A system for generating a run-time instance is also described including a hierarchical object transformation model configured to receive an expression from a parser, a compiler configured to generate a token for the expression using a node and an axis type, and a context builder configured to select an operation using the axis type and generate the run-time instance using the operation.

1 . A method for generating a run-time instance, comprising: 
 taking an expression from a parser;    tokenizing the expression using a node and an axis type;    selecting an operation using the axis type; and    generating the run-time instance using the operation.    
   
   
       2 . A method as recited in  claim 1 , further comprising developing an object model using the node and axis type.  
   
   
       3 . A method as recited in  claim 1 , further comprising developing an object model using the node and axis type, wherein node determines a corresponding node in an object tree associated with the object model.  
   
   
       4 . A method as recited in  claim 1 , further comprising evaluating the node to render a hierarchical transformation object model and an application-specific object model to generate the run-time instance.  
   
   
       5 . A method as recited in  claim 1 , wherein the expression is an XPath expression.  
   
   
       6 . A method as recited in  claim 1 , wherein taking an expression from a parser further comprises parsing an expression from a construct.  
   
   
       7 . A method as recited in  claim 1 , wherein taking an expression from a parser further comprises parsing an expression from an XSLT construct.  
   
   
       8 . A method as recited in  claim 1 , wherein taking an expression from a parser further comprises parsing an expression from a transformation specification.  
   
   
       9 . A method as recited in  claim 1 , wherein generating the run-time instance using the operation further comprises analyzing the expression to generate a schema.  
   
   
       10 . A method as recited in  claim 1 , wherein generating the run-time instance using the operation further comprises evaluating the expression to generate an object in an object model.  
   
   
       11 . A method as recited in  claim 1 , further comprising processing the node to generate the run-time instance.  
   
   
       12 . A method as recited in  claim 11 , wherein processing the node further comprises determining whether a root node exists.  
   
   
       13 . A method as recited in  claim 11 , wherein processing the node further comprises: 
 determining whether a root node exists; and    creating the root node if a determination is made that the root node does not exist.    
   
   
       14 . A method as recited in  claim 11 , wherein processing the node further comprises: 
 determining whether a root node exists;    creating the root node if a determination is made that the root node does not exist; and    creating a new node in the run-time instance using the operation.    
   
   
       15 . A method as recited in  claim 11 , wherein processing the node further comprises: 
 determining whether a root node exists;    creating the root node if a determination is made that the root node does not exist;    creating a new node in the run-time instance using the operation; and    replacing a current node with the new node.    
   
   
       16 . A system for generating a run-time instance, comprising: 
 a hierarchical object transformation model configured to receive an expression from a parser;    a compiler configured to generate a token for the expression using a node and an axis type; and    a context builder configured to select an operation using the axis type and generate the run-time instance using the operation.    
   
   
       17 . A computer program product for generating a run-time instance, the computer program product being embodied in a computer readable medium and comprising computer instructions for: 
 taking an expression from a parser;    tokenizing the expression using a node and an axis type;    selecting an operation using the axis type; and    generating the run-time instance using the operation.
