Abstract methods

def translateAssignment(id: Identifier, e: ExpressionOrRef, tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): StatementType

Translates an assignment from TeSSLa Core into the target representation

Translates an assignment from TeSSLa Core into the target representation

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The expression assigned to id

id

The id which is assigned

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated assignment

def translateBody(body: Map[Identifier, DefinitionExpression], ret: ExpressionOrRef, tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): Seq[StatementType]

Translates a block of statements with return expression (i.e. the body of a lambda) to statements

Translates a block of statements with return expression (i.e. the body of a lambda) to statements

Attributes

body

The sequence of statements to be translated

defContext

Definition context depicting all var names in the current scope to their definition expression

ret

The return expression of the block

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated block. Contains a IntermediateCode.ReturnStatement at the end

def translateExpressionOrRef(e: ExpressionOrRef, tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): ExpressionType

Translates an ExpressionOrRef to a corresponding expression

Translates an ExpressionOrRef to a corresponding expression

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The expression to be translated

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated expression

def translateExtern(e: ExternExpression, tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): ExpressionType

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

Translates an ExternExpression. If the extern is of function type a lambda expression is wrapped around it. If the extern is directly applied this lambda is most likely unnecessary and this function should not be used for translation of the called extern.

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated expression

def translateFunction(e: FunctionExpression, tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): ExpressionType

Translates a TeSSLa Core FunctionExpression to an expression

Translates a TeSSLa Core FunctionExpression to an expression

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The function to be translated

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated function expression

def translateFunctionCall(e: ExpressionOrRef, args: Seq[ExpressionType], tm: TypeArgManagement, defContext: Map[Identifier, DefinitionExpression]): ExpressionType

Translates a function application to the target representation

Translates a function application to the target representation

Attributes

args

The argument expressions of the application

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The function expression which is applied

tm

The TypeArgManagement to resolve type parameters

Returns:

The translated function application

Concrete methods

protected def finalAssignmentPossible(e: ExpressionOrRef): Boolean

Checks whether a given expression only uses identifiers from definedIdentifiers, i.e. those already defined

Checks whether a given expression only uses identifiers from definedIdentifiers, i.e. those already defined

Attributes

e

Expression to be examined

Returns:

Whether all subexpressions are already defined and and the expression can hence be evaluated

protected def getInlinedArgs(args: Seq[ExpressionOrRef], defContext: Map[Identifier, DefinitionExpression]): Seq[ExpressionOrRef]

Inlines all references in a function application's parameters according to inlining information from ExtendedSpecification

Inlines all references in a function application's parameters according to inlining information from ExtendedSpecification

Attributes

args

The arguments applied to e

defContext

Definition context depicting all var names in the current scope to their definition expression

Returns:

The modified parameter expressions

protected def inlineVars(e: DefinitionExpression, defContext: Map[Identifier, DefinitionExpression]): DefinitionExpression

Inlines all ExpressionRef (variable references) to variables in the inlining set of the ExtendedSpecification in a DefinitionExpression except those of function type

Inlines all ExpressionRef (variable references) to variables in the inlining set of the ExtendedSpecification in a DefinitionExpression except those of function type

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The expression where variable references should be inlined

Returns:

The modified expression

protected def inlineVarsBody(body: Map[Identifier, DefinitionExpression], defContext: Map[Identifier, DefinitionExpression]): Map[Identifier, DefinitionExpression]

Applies inlineVars on all statements in body

Applies inlineVars on all statements in body

Attributes

body

Sequence of statements where inlineVars is applied on

defContext

Definition context depicting all var names in the current scope to their definition expression

Returns:

The modified body

protected def inlineVarsRef(e: ExpressionOrRef, defContext: Map[Identifier, DefinitionExpression]): ExpressionOrRef

Inlines all ExpressionRef (variable references) to variables in the inlining set of the ExtendedSpecification in an ExpressionOrRef except those of function type

Inlines all ExpressionRef (variable references) to variables in the inlining set of the ExtendedSpecification in an ExpressionOrRef except those of function type

Attributes

defContext

Definition context depicting all var names in the current scope to their definition expression

e

The expression where variable references should be inlined

Returns:

The modified expression

Concrete fields

protected var definedIdentifiers: Map[Identifier, DeclarationType]

Set of identifiers which are assigned with final assignments. If an assignment uses exclusively existing assignments it can also be finally assigned Otherwise (in case of recursion) it must be assigned with a dummy default value first
