Field Details

dataType

public static final BooleanDataType dataType

Constructor Details

BooleanDataType

public BooleanDataType()

Constructs a new Boolean datatype.

BooleanDataType

public BooleanDataType(DataTypeManager dtm)

Method Details

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 AbstractIntegerDataType

Parameters:

settings - settings which may influence the result or null

Returns:

the mnemonic for this DataType.

getDecompilerDisplayName

public String getDecompilerDisplayName(DecompilerLanguage language)

Description copied from class: BuiltIn

Return token used to represent this type in decompiler/source-code output

Overrides:

getDecompilerDisplayName in class BuiltIn

Parameters:

language - is the language being displayed

Returns:

the name string

getCDeclaration

public String getCDeclaration()

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 of this DataType as a number of 8-bit bytes.

For primitive datatypes this reflects the smallest varnode which can be used to contain its value (i.e., raw data length).

Example: For x86 32-bit gcc an 80-bit long double raw data length of 10-bytes will fit within a floating point register while its aligned-length of 12-bytes is used by the gcc compiler for data/array/component allocations to maintain alignment (i.e., sizeof(long double) ).

NOTE: Other than the VoidDataType, no datatype should ever return 0, even if DataType.isZeroLength(), and only Dynamic/FactoryDataType 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

Returns the interpreted data value as an instance of the advertised value class.

For instance, Pointer data types should return an Address object (or null), or integer data types should return a Scalar object.

Specified by:

getValue in interface DataType

Overrides:

getValue in class AbstractIntegerDataType

Parameters:

buf - the data buffer

settings - the settings to use.

length - indicates the maximum number of bytes that may be consumed by a Dynamic datatype, otherwise this value is ignored. A value of -1 may be specified to allow a Dynamic datatype to determine the length based upon the actual data bytes

Returns:

the data object, or null if data is invalid

getValueClass

public Class<?> getValueClass(Settings settings)

Description copied from interface: DataType

Get the Class of the value Object to be returned by this datatype (see DataType.getValue(MemBuffer, Settings, int)).

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 datatype 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 String getRepresentation(MemBuffer buf,
 Settings settings,
 int length)

Description copied from interface: DataType

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

Specified by:

getRepresentation in interface DataType

Overrides:

getRepresentation in class AbstractIntegerDataType

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.

getRepresentation

public String getRepresentation(BigInteger bigInt,
 Settings settings,
 int bitLength)

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.

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 may be made directly to this instance if supported or to a DataType.copy(DataTypeManager) of this type.

Parameters:

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

Returns:

cloned instance which may be the same as this instance

getDefaultLabelPrefix

public String getDefaultLabelPrefix()

Description copied from interface: DataType

Returns the appropriate string to use as the default label prefix in the absence of any data.

Specified by:

getDefaultLabelPrefix in interface DataType

Overrides:

getDefaultLabelPrefix in class AbstractIntegerDataType

Returns:

the default label prefix or null if none specified.

getOppositeSignednessDataType

public AbstractIntegerDataType getOppositeSignednessDataType()

Specified by:

getOppositeSignednessDataType in class AbstractIntegerDataType

Returns:

the data-type with the opposite signedness from this data-type. For example, this method on IntegerDataType will return an instance of UnsignedIntegerDataType.
