Method Summary

Modifier and Type	Method	Description
DataType	clone(DataTypeManager dtm)	Returns an instance of this DataType with its universalID and SourceArchive identity retained.
java.lang.String	getCTypeDeclaration(DataOrganization dataOrganization)	Returns null for FactoryDataType (which should never be used) and Dynamic types which should generally be replaced by a primitive array (e.g., char[5]) or, a primitive pointer (e.g., char *).
int	getLength()	Get the length (number of 8-bit bytes) of this DataType.
boolean	hasLanguageDependantLength()	Indicates if the length of this data-type is determined based upon the DataOrganization obtained from the associated DataTypeManager.

Field Detail

dataType

public static final LongDoubleDataType dataType

Constructor Detail

LongDoubleDataType

public LongDoubleDataType()

Creates a Double data type.

LongDoubleDataType

public LongDoubleDataType(DataTypeManager dtm)

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

getCTypeDeclaration

public java.lang.String getCTypeDeclaration(DataOrganization dataOrganization)

Description copied from class: BuiltIn

Returns null for FactoryDataType (which should never be used) and Dynamic types which should generally be replaced by a primitive array (e.g., char[5]) or, a primitive pointer (e.g., char *). For other types an appropriately sized unsigned integer typedef is returned.

Specified by:

getCTypeDeclaration in interface BuiltInDataType

Overrides:

getCTypeDeclaration in class AbstractFloatDataType

Parameters:

dataOrganization - or null for default

Returns:

definition C-statement (e.g., #define or typedef) or null if type name is a standard C-primitive name or if type is FactoryDataType or Dynamic.

See Also:

BuiltInDataType.getCTypeDeclaration(ghidra.program.model.data.DataOrganization)

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

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
