Field Detail

dataType

public static final PcRelative31AddressDataType dataType

Constructor Detail

PcRelative31AddressDataType

public PcRelative31AddressDataType()

Creates a PC relative address data type using the bottom 31 bits.

PcRelative31AddressDataType

public PcRelative31AddressDataType(DataTypeManager dtm)

Creates a PC relative address data type using the bottom 31 bits.

Parameters:

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

Method Detail

getBuiltInSettingsDefinitions

protected SettingsDefinition[] getBuiltInSettingsDefinitions()

Description copied from class: BuiltIn

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

Overrides:

getBuiltInSettingsDefinitions in class BuiltIn

Returns:

a list of the settingsDefinitions used by this datatype.

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.

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 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

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 DataTypeImpl

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.

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.
