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
-
getDescription
public java.lang.String getDescription()
Description copied from interface:DataType
Get a String briefly describing this DataType.- Returns:
- a one-liner describing this DataType.
-
getMnemonic
public java.lang.String getMnemonic(Settings settings)
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
-
getRepresentation
public java.lang.String getRepresentation(MemBuffer buf, Settings settings, int length)
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
public java.lang.Object getValue(MemBuffer buf, Settings settings, int length)
Description copied from interface:DataType
Get the data in the form of the appropriate Object for this DataType.For instance if the datatype is an AddressDT, return an Address object. a Byte, return a Scalar* (maybe this should be a Byte) a Float, return a Float
- Parameters:
buf
- the data buffer.settings
- the settings to use.length
- the number of bytes to get the value from.- Returns:
- the data Object.
-
isEncodable
public boolean isEncodable()
Description copied from interface:DataType
Check if this type supports encoding (patching)If unsupported,
DataType.encodeValue(Object, MemBuffer, Settings, int)
andDataType.encodeRepresentation(String, MemBuffer, Settings, int)
will always throw an exception. Actions which rely on eitherencode
method should not be displayed if the applicable datatype is not encodable.- Specified by:
isEncodable
in interfaceDataType
- Overrides:
isEncodable
in classAbstractDataType
- Returns:
- true if encoding is supported
-
encodeValue
public byte[] encodeValue(java.lang.Object value, MemBuffer buf, Settings settings, int length) throws DataTypeEncodeException
Description copied from interface:DataType
Encode bytes from an Object appropriate for this DataType.Converts the given object to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the object may come from a user script. For example, a floating-point value may be rounded. Invalid values should be rejected with a
DataTypeEncodeException
.- Specified by:
encodeValue
in interfaceDataType
- Overrides:
encodeValue
in classAbstractDataType
- Parameters:
value
- the desired value.buf
- a buffer representing the eventual destination of the bytes.settings
- the settings to use.length
- the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.- Returns:
- the encoded value.
- Throws:
DataTypeEncodeException
- if the value cannot be encoded for any reason, e.g., incorrect type, not enough space, buffer overflow, unsupported (seeDataType.isEncodable()
).
-
encodeRepresentation
public byte[] encodeRepresentation(java.lang.String repr, MemBuffer buf, Settings settings, int length) throws DataTypeEncodeException
Description copied from interface:DataType
Encode bytes according to the display format for this type.Converts the given representation to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the representation is likely coming from user input. For example, a floating-point value may be rounded. Invalid representations should be rejected with a
DataTypeEncodeException
.- Specified by:
encodeRepresentation
in interfaceDataType
- Overrides:
encodeRepresentation
in classAbstractDataType
- Parameters:
repr
- the representation of the desired value, as inDataType.getRepresentation(MemBuffer, Settings, int)
. The supported formats depend on the specific datatype and its settings.buf
- a buffer representing the eventual destination of the bytes.settings
- the settings to use for the representation.length
- the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.- Returns:
- the encoded value.
- Throws:
DataTypeEncodeException
- if the value cannot be encoded for any reason, e.g., incorrect format, not enough space, buffer overflow, unsupported (seeDataType.isEncodable()
).
-
getValueClass
public java.lang.Class<?> getValueClass(Settings settings)
Description copied from interface:DataType
Get the Class of the value to be returned by this datatype.- 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.
