IvmlOrderedEnumMinMaxOperationDescriptor

IvmlOrderedEnumMinMaxOperationDescriptor()

For serialization.

IvmlOrderedEnumMinMaxOperationDescriptor

IvmlOrderedEnumMinMaxOperationDescriptor(TypeDescriptor<?> declaringType,
                                         IvmlOrderedEnumMinMaxOperationDescriptor.OperationKind operation)

Creates a new min/max operation descriptor.

Parameters:

declaringType - the declaring type

operation - the kind of operation to execute

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

IMetaOperation.isCompatible(java.lang.Class<?>, java.lang.Object...)

min

private EnumValue min(EnumValue v1,
                      EnumValue v2)

Returns the minimum enumeration value.

Parameters:

v1 - the first value to compare

v2 - the second value to compare

Returns:

the minimum of both values

max

private EnumValue max(EnumValue v1,
                      EnumValue v2)

Returns the maximum enumeration value.

Parameters:

v1 - the first value to compare

v2 - the second value to compare

Returns:

the maximum of both values
