Field Detail

dataType

public static final DwarfEncodingModeDataType dataType

Constructor Detail

DwarfEncodingModeDataType

public DwarfEncodingModeDataType()

Data type whose value indicates the type of Dwarf encoding used for other data.

DwarfEncodingModeDataType

public DwarfEncodingModeDataType(DataTypeManager dtm)

Data type whose value indicates the type of Dwarf encoding used for other data.

Parameters:

dtm - the data type manager associated with this data type.

Method Detail

clone

public DataType 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.

Parameters:

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

Returns:

cloned instance which may be the same as this instance

getMnemonic

public java.lang.String getMnemonic(Settings settings)

Description copied from interface: DataType

Get the mnemonic for this DataType.

Specified by:

getMnemonic in interface DataType

Overrides:

getMnemonic in class AbstractDataType

Parameters:

settings - settings which may influence the result or null

Returns:

the mnemonic for this DataType.

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

getDescription

public java.lang.String getDescription()

Description copied from interface: DataType

Get a String briefly describing this 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 datatype is an AddressDT, return an Address object. a Byte, return a Scalar* (maybe this should be a Byte) a Float, return a Float

Parameters:

buf - the data buffer.

settings - the settings to use.

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

Returns:

the data Object.

getRepresentation

public java.lang.String getRepresentation(MemBuffer buf,
                                          Settings settings,
                                          int length)

Description copied from interface: DataType

Get bytes from memory in a printable format for this type.

Parameters:

buf - the data.

settings - the settings to use for the representation.

length - the number of bytes to represent.

Returns:

the representation of the data in this format, never null.
