Constructor Details

AbstractComplexDataType

public AbstractComplexDataType(String name,
 AbstractFloatDataType floats,
 DataTypeManager dtm)

Method Details

getDefaultComplexDataType

protected static AbstractComplexDataType getDefaultComplexDataType(int size)

getComplexDataType

public static DataType getComplexDataType(int size,
 DataTypeManager dtm)

getMnemonic

public 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 String getDescription()

Description copied from interface: DataType

Get a String briefly describing this DataType.

Returns:

a one-liner describing this DataType.

getValue

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

Description copied from interface: DataType

Get the interpretted data value in the form of the appropriate Object for this DataType. This method must return a value consistent with DataType.getValueClass(Settings).

For instance, if this datatype is a Pointer an Address object or null should be returned. A Byte, returns a Scalar object.

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 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.
