Direct Known Subclasses:

RepeatedStringDataType

public abstract class RepeatCountDataType
extends DynamicDataType

Base abstract data type for a Dynamic structure data type that contains some number of repeated data types. The first entry contains the number of repeated data types to follow. Immediately following the first element are the repeated data types. The dynamic structure looks like this: RepeatDataType number = N - two bytes, little endian RepDT1 repDT2 ... repDTN

Method Detail

getAllComponents

protected DataTypeComponent[] getAllComponents(MemBuffer buf)

Description copied from class: DynamicDataType

Get all dynamic components associated with the specified MemBuffer

Specified by:

getAllComponents in class DynamicDataType

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.

See Also:

DynamicDataType.getAllComponents(ghidra.program.model.mem.MemBuffer)

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.

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.

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

Parameters:

settings - settings which may influence the result or null

Returns:

the mnemonic for this DataType.
