getComponentAt
@Deprecated(forRemoval=true, since="10.1") Data getComponentAt(int offset)
Deprecated, for removal: This API element is subject to removal in a future version.method name has been changed to better reflect behavior. The methodgetComponentContaining(int)
should be used instead.Return the first immediate child component that contains the byte at the given offset. It is important to note that with certain datatypes there may be more than one component containing the specified offset (seegetComponentsContaining(int)
).- Parameters:
offset
- the amount to add to this data items address to get the address of the requested data item.- Returns:
- first data component containing offset or null
-
getComponentContaining
Data getComponentContaining(int offset)
RReturn the first immediate child component that contains the byte at the given offset. It is important to note that with certain datatypes there may be more than one component containing the specified offset (seegetComponentsContaining(int)
).- Parameters:
offset
- the amount to add to this data items address to get the- Returns:
- first data component containing offset or null address of the requested data item.
-
getComponentsContaining
java.util.List<Data> getComponentsContaining(int offset)
Returns a list of all the immediate child components that contain the byte at the given offset.For a union, this will return all the components (if the offset is 0). The presence of bit-fields or zero-length components may cause multiple components to be returned.
- Parameters:
offset
- the amount to add to this data items address to get the address of the requested data item.- Returns:
- a list of all the immediate child components that contain the byte at the given offset or null if offset is out of bounds.
-
getPrimitiveAt
Data getPrimitiveAt(int offset)
Returns the primitive component containing this offset (i.e., one that does not have sub-components). This is useful for data items which are made up of multiple layers of other data items. This method immediately goes to the lowest level data item. If the minimum offset of a component is specified, the only first component containing the offset will be considered (e.g., 0-element array).- Parameters:
offset
- the offset- Returns:
- primitive component containing this offset
-
getComponentIndex
int getComponentIndex()
Get the index of this component in its parent- Returns:
- -1 if this data item is not a component of another data item.
-
getComponentLevel
int getComponentLevel()
Get this data's component level in its hierarchy of components.- Returns:
- the level of this data item with 0 being the level of top data items.
-

- the string
-
getDefaultLabelPrefix
java.lang.String getDefaultLabelPrefix(DataTypeDisplayOptions options)

options
- the options- Returns:
- the prefix
