IvmlConfigurationOperationDescriptor()

For serialization.

IvmlConfigurationOperationDescriptor

IvmlConfigurationOperationDescriptor(TypeDescriptor<?> declaringType,
                                     DecisionVariableDeclaration var)

Creates the operation descriptor.

Parameters:

declaringType - the declaring type

var - the variable to create the descriptor for

Method Detail

isCompatible

public IMetaOperation.CompatibilityResult isCompatible(java.lang.Class<?> retType,
                                                       java.lang.Object... params)

Description copied from interface: IMetaOperation

Returns whether the operation represented by this instance is compatible to the given return type and parameters. This method does not consider possible unnamed parameter rather than the underlying Java parameter.

Parameters:

retType - the return type (may be null in order to ignore this parameter)

params - the parameters (may be null if there are none, may be classes)

Returns:

an instance of IMetaOperation.CompatibilityResult denoting the actual compatibility level

invoke

public java.lang.Object invoke(java.lang.Object... args)
                        throws VilException

Description copied from interface: IMetaOperation

Invokes the specified operation. This method does not consider possible unnamed parameter rather than the underlying Java parameter. In case of IMetaOperation.acceptsNamedParameters() the caller must ensure that the last parameter is a map<String, Object> containing the named parameters.

Parameters:

args - the arguments, in case of non-static operations the first argument must be the object to execute on

Returns:

the result of the execution

Throws:

VilException - if the invocation fails
