Constructor Detail

StrategyCallExpression

StrategyCallExpression()
                throws VilException

Constructor for serialization.

Throws:

VilException - shall not happen

StrategyCallExpression

public StrategyCallExpression(java.lang.Object parent,
                              java.lang.String name,
                              Expression... arguments)
                       throws VilException

Creates a new instantiator strategy call.

Parameters:

parent - the parent language unit (if given used as optional parameter during calls)

name - the name of the call

arguments - the parameter for the call

Throws:

VilException - in case that no argument is given

StrategyCallExpression

public StrategyCallExpression(java.lang.Object parent,
                              java.lang.String name,
                              CallArgument... arguments)
                       throws VilException

Creates a new instantator strategy call.

Parameters:

parent - the parent language unit (if given used as optional parameter during calls)

name - the name of the call

arguments - the parameter for the call

Throws:

VilException - in case that no argument is given

StrategyCallExpression

public StrategyCallExpression(VariableDeclaration nameVar,
                              Expression... arguments)
                       throws VilException

Creates a new system execution strategy call.

Parameters:

nameVar - the variable holding the actual name/path of the executable

arguments - the parameter for the call

Throws:

VilException - in case that no argument is given

StrategyCallExpression

public StrategyCallExpression(VariableDeclaration nameVar,
                              CallArgument... arguments)
                       throws VilException

Creates a new system execution strategy call.

Parameters:

nameVar - the variable holding the actual name/path of the executable

arguments - the parameter for the call

Throws:

VilException - in case that no argument is given

Method Detail

setTypeRegistry

public void setTypeRegistry(TypeRegistry registry)

Defines the type registry to be used for resolving this call. The type registry is transient and used only during resolution of instantiator calls.

Parameters:

registry - the type registry to use

getNameVariable

public VariableDeclaration getNameVariable()

Returns the variable declaration holding the actual name.

Returns:

the variable declaration holding the actual name

doZeroArgumentTest

protected boolean doZeroArgumentTest()

Returns whether the zero argument test shall be applied.

Overrides:

doZeroArgumentTest in class CallExpression

Returns:

true if the test shall be applied, false else

getType

public StrategyCallExpression.Type getType()

Returns the type of this call.

Returns:

the type of this call

inferType

public TypeDescriptor<?> inferType()
                            throws VilException

Description copied from class: Expression

Infers the type of this expression including the type of the contained sub-expressions.

Overrides:

inferType in class CallExpression

Returns:

the type of this expression

Throws:

VilException - in case that inferring the type fails

inferTypeExecute

private TypeDescriptor<?> inferTypeExecute()
                                    throws VilException

Resolves the expression for system call execution.

Returns:

the type of executing a system call

Throws:

VilException - in case that the operands are not compatible

determineOperand

protected TypeDescriptor<?> determineOperand()
                                      throws VilException

Description copied from class: CallExpression

Determines the operand for searching operations on. Is called by CallExpression.inferType().

Overrides:

determineOperand in class CallExpression

Returns:

the operand

Throws:

VilException - in case that determining the operand fails
