RTTI0DataType
public RTTI0DataType()Creates a dynamic Type Descriptor data type. -
RTTI0DataType
Creates a dynamic Type Descriptor data type.- Parameters:
dtm
- the data type manager for this data type.
-
-
Method Details
-
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.- Parameters:
dtm
- the data-type manager instance whose data-organization should apply.- Returns:
- cloned instance which may be the same as this instance
-
getDescription
Description copied from interface:DataType
Get a String briefly describing this DataType.- Returns:
- a one-liner describing this DataType.
-
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.
-
getRepresentation
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.
-
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.- 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
-
getAllComponents
Description copied from class:DynamicDataType
Get all dynamic components associated with the specified MemBuffer- Specified by:
getAllComponents
in classDynamicDataType
- Parameters:
buf
- memory buffer positioned at start of data type instance- Returns:
- all components or null if memory data is not valid for this data type.
-
getVFTableAddress
Gets the address of the vf table or null if one isn't indicated.- Parameters:
memory
- the program memory containing the addressrtti0Address
- the address for the RTTI 0- Returns:
- the address of the vf table or null.
-
getSpareDataAddress
Gets the address of the spare data, a 0 address if there is no spare data, or null.- Parameters:
memory
- the program memory containing the addressrtti0Address
- the address for the RTTI 0- Returns:
- the address of the spare data, a 0 value, or null.
-
getVFTableName
Gets the type name for this descriptor.- Parameters:
buf
- the memory buffer where data has been created with this data type.- Returns:
- the name
-
getLength
Gets the total length of the data created when this data type is placed at the indicated address in memory.- Parameters:
memory
- the program memory for this data.address
- the start address of the data.bytes
- the bytes for this data.- Returns:
- the length of the data. zero is returned if valid data can't be created at the indicated address using this data type.
-
isValid
public boolean isValid(Program program, Address startAddress, DataValidationOptions validationOptions) Description copied from class:RTTIDataType
Determines if the data type is valid for placing at the indicated address in the program.- Specified by:
isValid
in classRTTIDataType
- Parameters:
program
- the programstartAddress
- the address where the validated data type will be used to create datavalidationOptions
- options indicating how to perform the validation- Returns:
- true if this data type can be laid down at the specified address
-
getLength
Gets the total length of the data created when this data type is placed at the indicated address in memory.- Parameters:
memory
- the program memory for this data.startAddress
- the start address of the data.- Returns:
- the length of the data. zero is returned if valid data can't be created at the indicated address using this data type.
-
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 interfaceDataType
- Overrides:
getDefaultLabelPrefix
in classAbstractDataType
- Returns:
- the default label prefix or null if none specified.
