Method Detail

isBlank

public static boolean isBlank(java.lang.String value)

Indicates whether the input String is either null or empty.

Parameters:

value - Value to check.

Returns:

true if blank.

newInstance

public static <T,E> T newInstance(java.lang.Class<T> clazz,
                                        java.lang.Class<E> expectedType,
                                        java.lang.String creatingAssetName,
                                        OfficeFloorIssues.AssetType assetType,
                                        java.lang.String assetName,
                                        OfficeFloorIssues issues)

Constructs a new instance of the input Class by its default constructor. If fails to instantiate, then reports issue via OfficeFloorIssues.

Type Parameters:

T - Type of object to instantiate.

E - Expected type that object is assignable.

Parameters:

clazz - Class to instantiate.

expectedType - Expected type that is to be instantiated.

creatingAssetName - Name of the Asset being created.

assetType - OfficeFloorIssues.AssetType.

assetName - Name of OfficeFloorIssues.AssetType.

issues - OfficeFloorIssues.

Returns:

New instance or null if not able to instantiate.

toArray

public static <O> O[] toArray(java.util.Map<java.lang.Integer,? extends O> map,
                              java.lang.Object[] type)

Transforms the input Map into an array by the type from indexes of the Map.

Type Parameters:

O - Element type.

Parameters:

map - Map to be transformed into an array.

type - Type of the array.

Returns:

Map contents as an array.

toArray

public static <T> T[] toArray(java.util.List<T> list,
                              java.lang.Object[] type)

Convenience method for List.toArray(Object[]) to pass compiler warnings for generic typed array.

Type Parameters:

T - Element type.

Parameters:

list - List to transform into an array.

type - Type of the array.

Returns:

List as an array.

getFunctionMetaData

public static ManagedFunctionMetaData<?,?> getFunctionMetaData(ManagedFunctionReference functionReference,
                                                                     ManagedFunctionLocator functionLocator,
                                                                     OfficeFloorIssues issues,
                                                                     OfficeFloorIssues.AssetType assetType,
                                                                     java.lang.String assetName,
                                                                     java.lang.String forItemDescription)

Obtains the ManagedFunctionMetaData reporting any failure to find to the OfficeFloorIssues.

Parameters:

functionReference - ManagedFunctionReference.

functionLocator - ManagedFunctionLocator to use to locate the ManagedFunctionMetaData.

issues - OfficeFloorIssues.

assetType - OfficeFloorIssues.AssetType for reporting issues.

assetName - Asset name for reporting issues.

forItemDescription - Description after "for" indicating what the ManagedFunctionMetaData is for.

Returns:
