Method Detail

isDynamicallySized

public boolean isDynamicallySized()

Description copied from interface: DataType

Indicates if this data-type is dynamically sized based upon DataOrganization.

Specified by:

isDynamicallySized in interface DataType

Overrides:

isDynamicallySized in class AbstractDataType

See Also:

DataType.isDynamicallySized()

getUndefinedDataType

public static DataType getUndefinedDataType(int size)

Get an Undefined data-type instance of the requested size

Parameters:

size - data type size, sizes greater than 8 will cause an Undefined1[size] (i.e., Array) to be returned.

Returns:

Undefined data type

getUndefinedDataTypes

public static Undefined[] getUndefinedDataTypes()

isUndefined

public static boolean isUndefined(DataType dataType)

Determine if the specified dataType is either a DefaultDataType, an Undefined data-type, or an Array of Undefined data-types.

Parameters:

dataType -

Returns:

true if dataType represents an undefined data-type in its various forms, else false.

isUndefinedArray

public static boolean isUndefinedArray(DataType dataType)

Determine if the specified dataType is an undefined array used to represent large undefined data.

Parameters:

dataType -

Returns:

true if the specified dataType is an undefined array used to represent large undefined data, otherwise false.
