Method Detail

concatContents

public static StringBuffer concatContents(List list)

Iterates through the passed in list and concatenates all the values of objects toString value to a StringBuffer and returns the StringBuffer.

Parameters:

list - the List of objects to concatenate.

Returns:

StringBuffer the concatenated contents of the list.

getOperationDeclaration

public static OperationDeclaration getOperationDeclaration(POperation operation)

Converts the passed operation to an instance of Operation for the passed in operation.

Parameters:

operation -

Returns:

VariableDeclarations

getVariableDeclarations

public static VariableDeclaration[] getVariableDeclarations(POperation operation)

Retrieves all the variable declarations for the passed in operation.

Parameters:

operation - the operation for which to retrieve the variable declarations.

Returns:

VariableDeclaration[]

getVariableDeclarations

public static VariableDeclaration[] getVariableDeclarations(AStandardDeclarator standardDeclarator)

Retrieves all the variable declarations for the passed in standardDeclarator.

Parameters:

standardDeclarator - the standard declartor for which to retrieve the VariableDeclaration instances.

Returns:

VariableDeclaration[]

newVariableDeclaration

protected static VariableDeclaration newVariableDeclaration(PVariableDeclaration variableDeclaration,
                                         PEqualExpression initialValue)

Creates a new VariableDeclaration from the passed in PVariableDeclaration.

Parameters:

variableDeclaration - the PVariableDeclaration that the new VariableDeclaration will be created from.

initialValue - the initial value of the variable declaration.

Returns:

VariableDeclaration the new VariableDeclaration

getVariableDeclarations

public static VariableDeclaration[] getVariableDeclarations(PVariableDeclarationList variableDeclarationList)

Creates an array of VariableDeclaration[] from the passed in PVariableDeclarationList.

Parameters:

variableDeclarationList - the PVariableDeclarationList that the new VariableDeclaration will be created from.

Returns:

VariableDeclaration[] the new VariableDeclaration array

getParameters

public static List getParameters(AFeatureCall featureCall)

Gets all the parameters from the featureCall instance.

Parameters:

featureCall - the featureCall for which to retrieve the parameters

Returns:

List the list containing any parameters retrieved, or an empty array if none could be retrieved

getParametersAsString

public static String getParametersAsString(AFeatureCall featureCall)

Gets all the parameters from the featureCall instance as a comma separated String.

Parameters:

featureCall - the featureCall from which to retrieve the parameters

Returns:

String the comma separated String

getParametersAsString

public static String getParametersAsString(PFeatureCallParameters featureCallParameters)

Gets all the parameters from the PFeatureCallParameters instance as a comma separated String.

Parameters:

featureCallParameters - the featureCallParameters from which to retrieve the parameters

Returns:

String the comma separated String

getLeftAndRightExpressions

public static String[] getLeftAndRightExpressions(PRelationalExpression relationalExpression)

Gets the left and right expressions of a PRelationalExpression and puts then into a List. The left expression will be the first expression in the list.

Parameters:

relationalExpression -

Returns:

the left and right parenthesis in [0] and [1] of the String[]

getType

public static String getType(TName name,
             List pathNameTail)

Concatenates the type from the passed in name and pathNameTail.

Parameters:

name - the starting name of the type

pathNameTail - the tail pieces of the name

Returns:

String the concatenated name.

getPrimaryExpression

public static String getPrimaryExpression(APropertyCallExpression expression)

Gets the "real" primary expression, as opposed to the primary expression retrieved from the parser syntax (since it leaves off any navigational relationships).

Parameters:

expression - the APosfixExpression instance for which to retrieve the primary expression

Returns:

String the "real" primary expression or the passed in expression.

getFeatureCalls

public static List getFeatureCalls(APropertyCallExpression expression)

Gets all feature calls from the passed in APropertyCallExpression instance.

Parameters:

expression - the APosfixExpression instance for which to retrieve the primary expression

Returns:

String the "real" primary expression of the passed in expression.

getArrowFeatureCallResultNavigationalPath

public static String getArrowFeatureCallResultNavigationalPath(APropertyCallExpression expression)

Gets the navigational path from the given expression that occurs after an arrow feature call. If the the expression contains an arrow feature call, then the navigational expression is any expression navigating on the result of an arrow feature call (otherwise it's an empty string).

Parameters:

expression - the expression from which to retrieve the navigational path.
