path
- category pathmissingBuiltInName
- name of missing built-in datatype for which this will standin for.missingBuiltInClassPath
- classpath of missing built-in datatype for which this will standin for.
-

Method Details
-
setCategory
protected void setCategory()set the category for this data type -
getMissingBuiltInName
Returns name of missing built-in datatype for which this type is standing-in for -
getMissingBuiltInClassPath
Returns classpath of missing built-in datatype for which this type is standing-in for -
getMnemonic
Description copied from interface:DataType
Get the mnemonic for this DataType.- Specified by:
getMnemonic
in interfaceDataType
- Overrides:
getMnemonic
in classAbstractDataType
- 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 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 itsaligned-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 ifDataType.isZeroLength()
, and onlyDynamic
/FactoryDataType
datatypes should return -1. IfDataType.isZeroLength()
is true a length of 1 should be returned. Where a zero-length datatype can be handled (e.g.,Composite
) theDataType.isZeroLength()
method should be used. -
canSpecifyLength
public boolean canSpecifyLength()Description copied from interface:Dynamic
Determine if the length may be specified for an instanceof this datatype (e.g.,Data
,Array
,DataTypeComponent
, etc.).- Specified by:
canSpecifyLength
in interfaceDynamic
- Returns:
- true if a user-specified length can be used, else false
-
getLength
Description copied from interface:Dynamic
Compute the length for this data-type which corresponds to the specified memory location.- Specified by:
getLength
in interfaceDynamic
- Parameters:
buf
- memory locationmaxLength
- maximum number of bytes to consume in computing length, or -1 for unspecified.- Returns:
- data length or -1 if it could not be determined. Returned length may exceed maxLength if data-type does not supported constrained lengths.
- See Also:
-
getDescription
Description copied from interface:DataType
Get a String briefly describing this DataType.- Specified by:
getDescription
in interfaceDataType
- Returns:
- a one-liner describing this DataType.
-
getRepresentation
Description copied from interface:DataType
Get bytes from memory in a printable format for this type.- Specified by:
getRepresentation
in interfaceDataType
- 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.
-
getValue
Description copied from interface:DataType
Returns the interpreted data value as an instance of theadvertised value class
.For instance,
Pointer
data types should return an Address object (or null), or integer data types should return aScalar
object.- Specified by:
getValue
in interfaceDataType
- Parameters:
buf
- the data buffersettings
- the settings to use.length
- indicates the maximum number of bytes that may be consumed by aDynamic
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
-
clone
Description copied from interface:DataType
Returns an instance of this DataType using the specifiedDataTypeManager
to allow its use of the correspondingDataOrganization
while retaining its unique identity (seeDataType.getUniversalID()
and archive association (seeDataType.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. -
copy
Description copied from interface:DataType
Returns a new instance (shallow copy) of this DataType with a new identity and no source archive association.Any reference to other datatypes will use
DataType.clone(DataTypeManager)
. -

- timestamp of last change within datatype manager

getCTypeDeclaration
Description copied from interface:BuiltInDataType
Generate a suitable C-type declaration for this data-type as a #define or typedef. Since the length of a Dynamic datatype is unknown, such datatypes should only be referenced in C via a pointer. FactoryDataTypes should never be referenced and will always return null.- Specified by:
