PcRelative31AddressDataType
public PcRelative31AddressDataType()Creates a PC relative address data type using the bottom 31 bits. -
PcRelative31AddressDataType
Creates a PC relative address data type using the bottom 31 bits.- Parameters:
dtm
- the data type manager associated with this data type.
-

Method Details
-
getBuiltInSettingsDefinitions
Description copied from class:BuiltIn
Gets a list of all the settingsDefinitions used by this datatype.- Overrides:
getBuiltInSettingsDefinitions
in classBuiltIn
- Returns:
- a list of the settingsDefinitions used by this datatype.
-
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 shuold be made directly to this instance if supported or to a
DataType.copy(DataTypeManager)
.- Parameters:
dtm
- the data-type manager instance whose data-organization should apply.- Returns:
- cloned instance which may be the same as this instance
-
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 (number of 8-bit bytes) of this DataType.NOTE: No datatype should ever return 0, even if
DataType.isZeroLength()
, and onlyDynamic
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.- Returns:
- the length of this DataType
-
getDescription
Description copied from interface:DataType
Get a String briefly describing this DataType.- Returns:
- a one-liner describing this DataType.
-
getValue
Description copied from interface:DataType
Get the interpretted data value in the form of the appropriate Object for this DataType. This method must return a value consistent withDataType.getValueClass(Settings)
.For instance, if this datatype is a
Pointer
an Address object or null should be returned. A Byte, returns aScalar
object.- 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
Description copied from interface:DataType
Get the Class of the value Object to be returned by this datatype (seeDataType.getValue(MemBuffer, Settings, int)
).- Specified by:
getValueClass
in interfaceDataType
- Overrides:
getValueClass
in classDataTypeImpl
- 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
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.
