Interface ParserContext

All Known Implementing Classes:

AbstractParserContext, ClassContext, DiagnosticContext, EClassContext, EInvocationContext, ModelContext, OperationContext, PropertyContext

public interface ParserContext

A ParserContext captures the context in which source text is parsed. A derived context is constructed with the relevant context, then createBaseResource creates a Concrete Syntax resource for a Concrete Syntax expression string. Then parse creates a corresponding Abstract Syntax ExpressionInOCL. initialize is invoked during the parse to install the derived context into the ExpressionInOCL.

Method Summary

BaseResource	createBaseResource(java.lang.String expression) Create a Concrete Syntax resource containing the parsed expression.
Type	getClassContext() Return the type of the self variable.
ExpressionInOCL	getExpression(BaseResource resource) Extract an Abstract Syntax ExpressionInOCL fronm a Concrete Syntax resource.
MetaModelManager	getMetaModelManager() Returbn the MetaModelManager in use.
void	initialize(Base2PivotConversion conversion, ExpressionInOCL expression) Callback to initialize the ExpressionInOCL with the derived context such as a contextvariable for the self type, parameter and result variables.
ExpressionInOCL	parse(java.lang.String expression) Create an Abstract Syntax ExpressionInOCL containing the parsed expression.

Method Detail

createBaseResource

BaseResource createBaseResource(java.lang.String expression)
                                throws java.io.IOException

Create a Concrete Syntax resource containing the parsed expression. Semantic errors may be found at the Resource.errors and may be converted to ParseExceptions by invoking PivitUtil.checkResourceErrors.

Throws:

java.io.IOException - if resource loading fails

getClassContext

Type getClassContext()

Return the type of the self variable.

getExpression

ExpressionInOCL getExpression(BaseResource resource)
                              throws ParserException

Extract an Abstract Syntax ExpressionInOCL fronm a Concrete Syntax resource.

Throws:

ParserException - if parsing fails

getMetaModelManager

MetaModelManager getMetaModelManager()

Returbn the MetaModelManager in use.

initialize

void initialize(Base2PivotConversion conversion,
                ExpressionInOCL expression)

Callback to initialize the ExpressionInOCL with the derived context such as a contextvariable for the self type, parameter and result variables.

parse

ExpressionInOCL parse(java.lang.String expression)
                      throws ParserException

Create an Abstract Syntax ExpressionInOCL containing the parsed expression.

Throws:

ParserException - if parsing fails
