Class AbstractParserContext

java.lang.Object

org.eclipse.ocl.pivot.internal.context.AbstractParserContext

All Implemented Interfaces:

ParserContext

Direct Known Subclasses:

AbstractExtendedParserContext, ClassContext, EClassContext, EObjectContext, ModelContext

public abstract class AbstractParserContext
extends Object
implements ParserContext

AbstractParserContext provides the default implementation of the ParserContext API that all clients should extend.

Method Detail

createBaseResource

public CSResource createBaseResource(String expression)
                              throws IOException,
                                     ParserException

Description copied from interface: ParserContext

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.

Specified by:

createBaseResource in interface ParserContext

Throws:

IOException - if resource loading fails

ParserException

getAttribution

public Attribution getAttribution(EObject eObject)

Specified by:

getAttribution in interface ParserContext

Since:

1.3

getClassContext

public Type getClassContext()

Description copied from interface: ParserContext

Return the type of the self variable.

Specified by:

getClassContext in interface ParserContext

getEnvironmentFactory

public EnvironmentFactoryInternal getEnvironmentFactory()

Description copied from interface: ParserContext

Return the EnvironmentFactory in use.

Specified by:

getEnvironmentFactory in interface ParserContext

getExpression

public ExpressionInOCL getExpression(CSResource resource)
                              throws ParserException

Description copied from interface: ParserContext

Extract an Abstract Syntax ExpressionInOCL fronm a Concrete Syntax resource.

Specified by:

getExpression in interface ParserContext

Throws:

ParserException - if parsing fails

getInstanceContext

public Type getInstanceContext()

getMetamodelManager

public PivotMetamodelManager getMetamodelManager()

Description copied from interface: ParserContext

Return the MetamodelManager in use.

Specified by:

getMetamodelManager in interface ParserContext

getRootElement

public Element getRootElement()

Description copied from interface: ParserContext

Optional pre-existing AS root element to be updated by the parse.

Specified by:

getRootElement in interface ParserContext

initialize

public void initialize(Base2ASConversion conversion,
                       ExpressionInOCL expression)

Description copied from interface: ParserContext

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

Specified by:

initialize in interface ParserContext

parse

public ExpressionInOCL parse(EObject owner,
                             String expression)
                      throws ParserException

Description copied from interface: ParserContext

Create an Abstract Syntax ExpressionInOCL containing the parsed expression on behalf of a potential owner.

This an invariant/precondition may specify its constraint as the owner
an operation body may specify the operation as the owner

The owner should be non-null but a null value is tolerated for deprecated compatibility.

Specified by:

parse in interface ParserContext

Throws:

ParserException - if parsing fails

setRootElement

public void setRootElement(Element rootElement)

Specified by:

setRootElement in interface ParserContext
