                       DataTypeManager dtm)

Method Detail

getFormatSettingsDefinition

protected FormatSettingsDefinition getFormatSettingsDefinition()

Description copied from class: AbstractIntegerDataType

Return the Format settings definition included in the settings definition array

Overrides:

getFormatSettingsDefinition in class AbstractIntegerDataType

Returns:

Format settings definition included in the settings definition array

See Also:

BuiltIn.getSettingsDefinitions()

getBuiltInSettingsDefinitions

protected SettingsDefinition[] getBuiltInSettingsDefinitions()

Description copied from class: BuiltIn

Gets a list of all the settingsDefinitions used by this datatype.

Overrides:

getBuiltInSettingsDefinitions in class AbstractIntegerDataType

Returns:

a list of the settingsDefinitions used by this datatype.

getCDeclaration

public java.lang.String getCDeclaration()

Returns the C style data-type declaration for this data-type. Null is returned if no appropriate declaration exists.

Overrides:

getCDeclaration in class AbstractIntegerDataType

Returns:

the C style data-type declaration for this data-type. Null is returned if no appropriate declaration exists.

getLength

public int getLength()

Description copied from interface: DataType

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

Specified by:

getLength in interface DataType

Returns:

the length of this DataType

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

getDescription

public java.lang.String getDescription()

Description copied from interface: DataType

Get a String briefly describing this DataType.

Specified by:

getDescription in interface DataType

Returns:

a one-liner describing this DataType.

getValue

public java.lang.Object getValue(MemBuffer buf,
                                 Settings settings,
                                 int length)

Description copied from interface: DataType

Get the data in the form of the appropriate Object for this DataType. For instance if the data type is an AddressDT, return an Address object. a Byte, return a Scalar* (maybe this should be a Byte) a Float, return a Float

Specified by:

getValue in interface DataType

Overrides:

getValue in class AbstractIntegerDataType

Parameters:

buf - the data buffer.

settings - the settings to use.

length - the number of bytes to get the value from.

Returns:

the data Object.

getValueClass

public java.lang.Class<?> getValueClass(Settings settings)

Description copied from interface: DataType

Get the Class of the value to be returned by this data type.

Specified by:

getValueClass in interface DataType

Overrides:

getValueClass in class AbstractIntegerDataType

Parameters:

settings - the relevant settings to use or null for default.

Returns:

Class of the value to be returned by this data type or null if it can vary or is unspecified. Types which correspond to a string or char array will return the String class.

clone

public CharDataType clone(DataTypeManager dtm)

Description copied from interface: DataType

Returns an instance of this DataType with its universalID and SourceArchive identity retained. The current instanceof 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.

Specified by:

clone in interface DataType

Parameters:

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

Returns:
