Method Detail

getMnemonic

public java.lang.String getMnemonic(Settings settings)

Description copied from interface: DataType

Get the mnemonic for this DataType.

Specified by:

getMnemonic in interface DataType

Overrides:

getMnemonic in class AbstractDataType

Returns:

the mnemonic for this DataType.

See Also:

DataType.getMnemonic(Settings)

getLength

public int getLength()

Description copied from interface: DataType

Get the length (number of 8-bit bytes) of this DataType.

Returns:

the length of this DataType

See Also:

DataType.getLength()

isDynamicallySized

public boolean isDynamicallySized()

Description copied from interface: DataType

Indicates if this data-type is dynamically sized based upon DataOrganization.

Specified by:

isDynamicallySized in interface DataType

Overrides:

isDynamicallySized in class AbstractDataType

See Also:

DataType.isDynamicallySized()

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.

See Also:

DataType.getDescription()

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 data type 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.

See Also:

ghidra.program.model.data.DataType#getValue(ghidra.program.model.mem.MemBuffer, ghidra.program.model.lang.ProcessorContext, ghidra.docking.settings.Settings, int)

getValueClass

public java.lang.Class<?> getValueClass(Settings settings)

Description copied from interface: DataType

Get the Class of the value to be returned by this data type.

Specified by:

getValueClass in interface DataType

Overrides:

getValueClass in class DataTypeImpl

Parameters:

settings - the relevant settings to use or null for default.

Returns:

Class of the value to be returned by this data type or null if it can vary or is unspecified. Types which correspond to a string or char array will return the String class.

getAddressValue

public static Address getAddressValue(MemBuffer buf,
                                      int size,
                                      int shift,
                                      AddressSpace targetSpace)

Generate an address value based upon bytes stored at the specified buf location

Parameters:

buf - memory buffer and stored pointer location

clone

public DataType clone(DataTypeManager dtm)

Description copied from interface: DataType

Returns a new instance of this DataType with its universalID and SourceArchive identity retained. Note: for built-in DataType's, clone and copy should have the same affect.

Parameters:

dtm - the data-type manager instance whose data-organization should apply.
