DoubleDataType

public DoubleDataType(DataTypeManager dtm)

Method Details

clone

public DataType clone(DataTypeManager dtm)

Description copied from interface: DataType

Returns an instance of this DataType using the specified DataTypeManager to allow its use of the corresponding DataOrganization while retaining its unique identity (see DataType.getUniversalID() and archive association (see DataType.getSourceArchive()) if applicable.

This instance will be returned if this datatype's DataTypeManager matches the specified dtm. The recursion depth of a clone will stop on any datatype whose DataTypeManager matches the specified dtm and simply use the existing datatype instance.

NOTE: In general, this method should not be used to obtain an instance to be modified. In most cases changes shuold be made directly to this instance if supported or to a DataType.copy(DataTypeManager).

Parameters:

dtm - the data-type manager instance whose data-organization should apply.

Returns:

cloned instance which may be the same as this instance

hasLanguageDependantLength

public boolean hasLanguageDependantLength()

Description copied from interface: DataType

Indicates if the length of this data-type is determined based upon the DataOrganization obtained from the associated DataTypeManager.

Specified by:

hasLanguageDependantLength in interface DataType

Overrides:

hasLanguageDependantLength in class AbstractDataType

Returns:

true length is language/compiler-specification dependent, else false

getLength

public int getLength()

Description copied from interface: DataType

Get the length (number of 8-bit bytes) of this DataType.

NOTE: No datatype should ever return 0, even if DataType.isZeroLength(), and only Dynamic datatypes should return -1. If DataType.isZeroLength() is true a length of 1 should be returned. Where a zero-length datatype can be handled (e.g., Composite) the DataType.isZeroLength() method should be used.

Returns:

the length of this DataType
